sipcapture/HEP msg sizes>1500
by Daniel Tryba 16 Aug '17

16 Aug '17

While looking into HOMER I saw that large INVITEs got truncated in the webinterface, looking at the HEP traffic these (UDP) messages got fragmented in transport (asterisk/res_hep) and I started to think these were not getting reassembled correctly. Only to find out the database schemas have set the msg size set to varchar(1500). Is there any good reason for not changing this to a bigger default?

RTP loops
by Mauro Costantini 16 Aug '17

16 Aug '17

Hi everyone, we have an installation with: - 1 kamailio instance - with 2 interface, one with public and one with private IP (for local communication to the db and asterisk ). We use keepalived service for failover and so, every interface has 2 IPs: the real one and the “virtual” one for the keepalived service - some asterisk instances for transcoding and billing - with one interface with private IP - 2 RTP (rtpengine) instances - with 2 interfaces, one with public and one with private IP A few times happens a loop on the RTPengine and we could see a lot of lines like this in the log: “Too many packets in UDP receive queue (more than 50), aborting loop. Dropped packets possible” This loop doesn't stop until all the resources are exhausted and it results in the freeze of the machine. We don’t understand the reason why these loops are generated. We have 2 cases: 1) we send an INVITE to the CPE (a Bria on iOS) The CPE answers with a "100 Trying", a "180 Ringing" and a few seconds later sends us 3 packets of "200 ok" with SDP like this: SIP/2.0 200 OK Via: SIP/2.0/UDP 178.250.x.y;branch=z9hG4bKb842.29952898c30d6d06b75b916618357ccd.2 Via: SIP/2.0/UDP 192.168.x.y:5090;rport=5090;branch=z9hG4bK7fd100fb Record-Route: <sip:178.250.x.y;r2=on;lr=on;ftag=as26b82ac7;did=cb5.0ce;nat=yes> Record-Route: <sip:192.168.x.z;r2=on;lr=on;ftag=as26b82ac7;did=cb5.0ce;nat=yes> Contact: <sip:6051018****@158.148.x.y:3180;rinstance=ffdff5e0142dfd2d> To: <sip:6051018****@192.168.x.z>;tag=29859d3c From: <sip:051438****@192.168.x.y>;tag=as26b82ac7 Call-ID: 698200851849894c5874186163abe668@192.168.x.y:5090 CSeq: 102 INVITE Allow: INVITE, ACK, CANCEL, BYE, REFER, INFO, NOTIFY, OPTIONS, UPDATE, PRACK, MESSAGE, SUBSCRIBE Content-Type: application/sdp Supported: replaces User-Agent: Bria iOS release 3.9.7 stamp 38887.38893 Content-Length: 230 v=0 o=- 1085831961 3 IN IP4 100.81.231.195 s=Cpc session c=IN IP4 100.81.231.195 t=0 0 m=audio 65454 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv Could the IP of the media part (100.81.231.195 in the CGNAT 100.64.0.0/10) be the cause of the loop?

[1] one of these strange ACKs, they are all different in content, but similar in structure: multiple Record-Route / Via, truncating too long message; [2] a "never ending" BYEs. After modifying the configuration adding some "listen=IP_ADDR:PORT" (and of course excluding the keepalive IP) we had no loops but is this enough? Why Kamailio generated the loops? Is there something else we should review in our config? Any advice would help a lot. Thanks. [0] https://goo.gl/rWh5db [1] https://goo.gl/MNShq9 [2] https://goo.gl/6mxepG

UAC reg_random_delay issue
by Ivo Vastert 16 Aug '17

16 Aug '17

Hi, I'm using the UAC module in Kamailio to setup about 500 outbound registration towards a single host. The issue I'm currently experiencing is that when we start Kamailio all this 500 registrations are initiated at once towards the host which can't handle all the requests at the same time. Therefor I tried to spread the registrations using the reg_random_delay function: modparam("uac", "reg_random_delay", 60) I would expect that this would spread the registrations over about a minute but in reality the registrations are spread as follow: Starttime / Registrations 21:59:14 151 21:59:15 166 21:59:16 127 21:59:18 60 21:59:22 35 So Kamailio is started at 21:59:14 and initiates 151 registrations, 1 second after start another 166 2 seconds after start another 127 4 seconds after start another 60 8 seconds after start the last 35 In reality it looks like some increment is applied instead of calculating a random starting offset for each outbound registration? Is there any solutions to this issue available? Best regards, Ivo Vastert

rtpengine : question about RTP/RTCP multiplexing (RFC 5761) and demultiplexing
by Abdoul Osséni 16 Aug '17

16 Aug '17

Hello All, I read rtpengine can multiplex and demultiplex RTP/RTCP. Cf.https://github.com/sipwise/rtpengine Example: UAC -> Kamailio + rtpengine -> Asterisk UAC and Asterisk don't support RFC 5761. Only rtpengine does. Does this mean that uac must be compliance with RFC 5761 if I want multiplex and demultiplex RTP/RTCP between UAC and rtpengine? Thanks. Abdoul.

Kamailio 4.3.4: receive_msg(): no via found in reply
by Grant Bagdasarian 15 Aug '17

15 Aug '17

Hello, We're testing kamailio 4.3.4 with two kamailio's communicating with each other. One of them is a gateway with rtpengine at the carrier side, the other is a basic sip router. When calling a destination and cancelling the INVITE a 487 is received from the carrier and directly ACK'd by the first kamailio and in turn is forwarded to the second. But the 487 response received by the 2nd kamailio doesn't have a Via header which results in kamailio printing the error: receive_msg(): no via found in reply. Any ideas why the forwarded 487 doesn't contain a Via header and how to fix this? Note: IP's are changed.

Reinvite, rewrite reply SDP?
by Yu Boot 15 Aug '17

15 Aug '17

Finally I find a root of a problem with my T.38 reinvites. A->(NAT)->Kami->PSTN When NATted caller does reinvite, and remote side answers with 200 OK+SDP, Kami (why?) doesn't rewrite SDP for its own IP (so NATted caller can receive RTP) and leaves remote's IP as media address, so of course there is no RTP/UDPTL. All other NAT related stuff works fine. Even if remote side sends me T.38 reinvite first, everything works properly. Config file is default from Kami sources. Any ideas?

RTPEngine recording
by Alex Balashov 14 Aug '17

14 Aug '17

I have gathered that RTPEngine has recently, or perhaps some time ago, evolved a recording feature set: https://kamailio.org/docs/modules/5.0.x/modules/rtpengine.html#rtpengine.f.… Does anyone have any experience using it with Kamailio? How does it work? Any gotchas or pitfalls? It looks like recording is done via a separate daemon specifically for that purpose. Does it emit directly in a playable format, or more or less just dump the raw, RTP-encapsulated frames? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

DNS Geo Location Kamailio servers, registration and routing
by Sadeesh Radhakrishnan 14 Aug '17

14 Aug '17

We have kamailio servers that do DNS-Geo-Location on different locations, using same domain name. So the users from a country will be preferred to his nearby server by DNS routing. Similarly users from different countries will be registering to their nearby kamailio sip servers. All the servers share a common user location table on database. Now the users are getting registered fine, with no issue. We want the users at one location should be able to call user@other-location using the user location contact information. When we tried, the INVITE is sent on common domain name and that reverse resolves dns to same server and gets a 404 not found. I need some suggestion / ideas in order to make it happen. Thanks

Inconsistency in sems v1.6 installation: sems.conf is missing
by leslie mekiyess 14 Aug '17

14 Aug '17

For some reason, the installation creates the etc directory under the /usr/local/etc/sems/ : make[2]: Entering directory `/usr/src/sems-1.6.0/apps/conf_auth' mkdir -p **/usr/local/etc/sems/**etc**/** installing conf_auth.conf make[2]: Leaving directory `/usr/src/sems-1.6.0/apps/conf_auth' Then at the make install ends the following is printed: *** install complete. Run SEMS with *** *** /usr/local/sbin/sems -f /**usr/local/etc/sems/sems.conf** At bottom libe, while following the spain document instructions, I figured out that the sems.conf wasn;t created at the /usr/local/etc/sems/ path. I can create a new one or even copy this one found : /usr/src/sems-1.6.0/apps/mobile_push/load_test/sems_cfg/core/etc/sems.conf but I am afraid of further files/directory inconsistencies. Any assistance is very appreciated.

Carrierroute, fallback, reinvites
by yu＠yu-boot.ru 12 Aug '17

12 Aug '17

Hello. Trying to implement fallback route for carrierroute and got sick to make reinvites working correctly. Until fallback route triggers, everything is OK. Anyone has working config for that purposes (NAT traversal, reinvites, carrierroute ), please? And abstract question - is it generally a good idea to implement a simple softswitch (not PBX like Asterisk) like Yate or Freeswitch with Kami? Now I just want to learn Kami and learn SIP deeper in general.

Dispatcher call id hash for server side invite
by Ryan Wagoner 11 Aug '17

11 Aug '17

For a call invite from a phone to an load balanced asterisk server farm I can use ds_select_dst with hash over callid for the algorithm. What I don't understand is what happens for a server side invite. Say user A calls user B. The server will send and invite to user B's device. User B's device will reply and ds_select_dst won't have the call id hash so it will choose a random server, which might not be the server sending the invite. How do I mark these server side invites so the call hash is known by kamailio? Or am I thinking about this the wrong way? Thanks, Ryan

Hi, I am facing an Problem in Dialplan Module. Scenario: ======== I am Dialling 00091xxxxxxxxxx number, I need to remove only the prefix 000, then the call placement will be 91xxxxxxxxxx. My dialplan rule: ============== MariaDB [kamailio]> select * from dialplan; +----+------+----+----------+-----------+-----------+-----------+----------+-------+ | id | dpid | pr | match_op | match_exp | match_len | subst_exp | repl_exp | attrs | +----+------+----+----------+-----------+-----------+-----------+----------+-------+ | 1 | 1 | 1 | 1 | ^000$ | 0 | ^000$ | | | +----+------+----+----------+-----------+-----------+-----------+----------+-------+ But the prefix 000 is not replaced. Please Guide me to Resolve this issue. Do I need to change somet rules?? Additional info: ============= But, With additional to the above dialplan data rule I used the below rule. +----+------+----+----------+-----------+-----------+-----------+----------+-------+ | id | dpid | pr | match_op | match_exp | match_len | subst_exp | repl_exp | attrs | +----+------+----+----------+-----------+-----------+-----------+----------+-------+ | 1 | 1 | 1 | 1 | ^000$ | 0 | ^000$ | | | 111 +----+------+----+----------+-----------+-----------+-----------+----------+-------+ The above rule replacing only the 000, If we Dial 000xxxx its omitting, While Dialing 000 its replacing that with 111.

Kamailio: how to route RTP media directly to endpoint
by wsotest.512 10 Aug '17

10 Aug '17

Hi all, We have usual config Kamailio + Asterisk where Kamailio play as sip and rtp proxy. Kamailio have public IP, asterisk - no. All calls between clients now going like that: UserA ---sip--> Kamailio --> Asterisk --> UserB \-rtp--> Kamailio (rtpproxy) --> Asterisk --> UserB All clients of course from Internet and behind Nat. Main problem is amount of traffic going through Kamailio and Asterisk. We need to pay for every additional GB behind limit in tariff plan to hosting provider. So we decided to try route all rtp traffic between users directly. UserA ---sip--> Kamailio --> Asterisk --> UserB \-rtp--> --> --> UserB Is it possible at all? Maybe someone already did it . -- BR, Alex

IMPORTANT: acc module - SQL define removed and diameter code relocated
by Daniel-Constantin Mierla 09 Aug '17

09 Aug '17

Hello, I just pushed a bit of clean up to acc module, therefore be aware of following changes: 1) the define conditions on SQL_ACC were removed -- this was enabled for more than 10 years and only made the code look complex and hard to follow up its logic. 2) the code related to DIAMETER accounting was relocated to acc_diameter (new) module. It was a consistent size of code that was not enabled for sooo... long. It is now a dedicated module, similar to acc_radius. The diameter accounting code, even a new module now, is in the same stage, compiling but not tested, in pair with auth_diameter module, it may work, but very likely not. In summary, what's important for those using the acc module -- it offers the same functionality as it was enabled by default in the past 10 years or more, only the unused code was relocated. It offers the functionality of writing accounting records to syslog and sql databases. The acc module is now slimmer, only with the code that it needs, therefore easier to maintain and enhance for the future. Hopefully, there was no side effect with this update -- anyhow, if you find any issue, just open a bug report on github project.

RFC: Moving misc/obsolete/ to its own git repository
by Daniel-Constantin Mierla 09 Aug '17

09 Aug '17

Hello, trying to make the git repository a bit slimmer and avoid unuseful indexing of unused modules, I am considering to move misc/obsolete to its own github repository (planned to be named kamailio-obsolete). The initial idea was to keep there modules that were duplicated or no longer maintained, just in case someone will come later and wants to revive it. However, iirc, it is more than 4 years and nobody touched them, so very likely it requires a bit of work to revive any of them, so a fresh re-import will be the same from an external repository. If anyone still wants to keep them in the main kamailio repository, respond on the mailing list and present the benefits. If not, I will do the operation in the next several days.

Core crash in del_lump() "offset exceeds message size" when using subst() inside tm:local-request route.
by Cody Herzog 08 Aug '17

08 Aug '17

Hello. Inside the tm:local-request route, I am trying to modify the body of outgoing NOTIFY messages using the subst_body() function. Things seem to work fine most of the time. The NOTIFY messages are correctly modified. However, I will very rarely hit a crash. I can force the crash to happen more quickly by stress testing with thousands of NOTIFY messages being modified. Is it safe to call subst() or subst_body() inside the tm:local-request route? If not, is there another way I can modify the outgoing NOTIFY messages safely? Note that I am also calling append_hf() inside the same tm:local-request route, but that has been working for a very long time without causing any problems. Could there be some kind of bad interaction between append_hf() and subst_body()? Strangely, it seems like using subst() makes the crash more likely to happen. For some reason, subst_body() seems to be more robust. Here are the logs I see: --------- Jul 28 10:57:40 SIPCOMM-VEGAS-TEST /usr/local/sbin/kamailio[2476]: CRITICAL: <core> [data_lump.c:292]: del_lump(): offset exceeds message size (1625 > 1194) aborting...

Forwarding call to dispatcher"); append_hf("X-External: true\r\n"); $rU = "00"+$rU; break; case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } ...... # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); So all calls going to asterisk server. Not local calls with 00 prefix. And asterisk context: context kamailio { _X. => { Noop(CALL to kamailio user ${EXTEN}); Dial(SIP/${EXTEN}@${SIPDOMAIN},60,RTt); Hangup; } _00X. => { Noop(CALL to external user ${EXTEN}); Dial(SIP/PSTN-SERVER/${EXTEN:2},60,RTt); Hangup; } } Is it right way? Maybe any better approach? How to keep route logic at kamailio, but use dispatcher asterisk to proccess the calls to pstn(all endpoints at one city to pstn asterisk at this city. In others city there are other pstn gateways)? -- Aydar A. Kamalov

Kamailio Server not relaying any message
by Rahman Afzal 08 Aug '17

08 Aug '17

Hi, I have an ongoing issue with kamailio...my softclient registered with kamilio originates a call which gets routed to another switch from kamilio and that switch terminates the call to B party side. Now once calls is established, B party sends BYE messages or (any re-INVITE during the dialog) which comes to the kamailio but kamailio is not relaying it to the A party...Can someone please help in this regard.

Some Fault messages I am trying to clear up

Hi list people: When using Siremis with Kamailio, I see this error: First Fault [2017-08-07 22:55:17 (GMT)] An exception occurred while executing this script: Error message: #256, Unable to location template file system_internal_error.tpl.

Question regarding t_check_trans()
by Joe Baran 07 Aug '17

07 Aug '17

Probably an elementary question, but we're relatively new at digging into the details. We are trying to understand the following block of config code and have a question or two. Our assumption is the t_precheck_trans() function tells us whether another packet has arrived already as a retransmission. However, we're not clear on what the t_check_trans() is doing assuming the condition is true. Any direction on this? Thanks. route[CHECK_RETRANS] { # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } } Joe Baran

Pull Request or Issue? - coredump in case no contentLengthHdr present in REGISTER
by Valentin Christoph 04 Aug '17

04 Aug '17

Hi all, We have identified an IMS related issue, when the "Content-Length" header is missing in REGISTER request. It's a missing null pointer check in file modules/ims_auth/utils.c We are using Kamailio 4.4.5 for this purpose and we would need a fix in that release. I'm not sure, how to proceed now? Should I just create an "Issue" at GitHub, or is it possible for me to create a "Pull Request" at GitHub (would be less effort for you, I guess). Anyway, the change we did in our local GIT repository, is shown in following picture: [cid:image001.jpg@01D30C76.DE88AE10] Thanks, Christoph The information contained in this e-mail message is privileged and confidential and is for the exclusive use of the addressee.

thx. I just thought that it's possibe to concatenate both engines together. So this is my last question regardng kemi: Main goal why i still not use kemi at the my projects is a: TBD: the options for specific event_route blocks. Meanwhile, should work using hybrid configuration with request_route/reply_route/… in embedded interpreter and the other routing blocks in native kamailio.cfg. As i uderstand it is not possible to use event_route in a kemi. only native.

route[LOCATION] is it bug?

Calls to other destination rejected by kamailio with 404. But If i put xlog("AAAA") or xwarn in route[LOCATION] in if (!lookup("location")) block (default kamailio 5.0.2 config) calls to other destination goes through dispatcher to asterisks. I cant't understand WHY? :( (sorry for my bad English) route[LOCATION] { #!ifdef WITH_SPEEDDIAL # search for short dialing - 2-digit extension if($rU=~"^[0-9][0-9]$") { if(sd_lookup("speed_dial")) { route(SIPOUT); } } #!endif #!ifdef WITH_ALIASDB # search in DB-based aliases if(alias_db_lookup("dbaliases")) { route(SIPOUT); } #!endif $avp(oexten) = $rU; if (!lookup("location")) { xwarn("method ($rm) r-uri ($ru)\n"); ################## HERE ########################## $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); exit; } -- Aydar A.

Kamailio inserting Quote " mark in SIP header

03 Aug '17

Hi All, We are seeing that Kamailio's nat_helper_module function of add_rcv_param(), inserts " (quote) mark to some of the SIP headers (as below in the contact header in sip 200 OK response) Contact: <sip:172.70.1.2:5060;bnc;received="sip:118.107.184.242:25090 ">;expires=172 We got few SIP UAs that are complaining about the quote mark inclusion in contact header and responding back with SIP 400 bad syntax status code. Requesting views / suggestions from community about this behavior of kamailio and any workarounds available. Cheers Arslan

Using a number as htable key name

03 Aug '17

Hello, I'm trying to use a htable to reroute some numbers but when i'm trying to use kamcmd to add a entry where the element name is a number instead of a string i get a 500 error kamcmd htable.seti force_number 1234 1 error: 500 - Not enough parameters (htable name, key name and value) Also with quotes i get the 500 error: kamcmd htable.seti force_number "1234" 1 error: 500 - Not enough parameters (htable name, key name and value) But this works: kamcmd htable.seti force_number a1234 1 Is there a way to escape this so i can use a number as element name?

Kamailio example configuration: auth section incomplete?
by George Diamantopoulos 02 Aug '17

02 Aug '17

Hello again, Still getting familiar with kamailio, and I'm wondering about the AUTH route in the example configuration file. Here's a reducted-simplified version of it for reference (from git master, without IP AUTH and comments): ______________________________________________ route[AUTH] { if (is_method("REGISTER") || from_uri==myself) { if (!auth_check("$fd", "subscriber", "1")) { auth_challenge("$fd", "0"); exit; } if(!is_method("REGISTER|PUBLISH")) consume_credentials(); } if (from_uri!=myself && uri!=myself) { sl_send_reply("403","Not relaying"); exit; } return; } ______________________________________________ So the way I see it, what happens is the following: * All REGISTERs will be challenged * All SIP messages with kamailio's aliases in the "From" header URI will be challenged * All SIP messages with no reference to kamailio's aliases in both R-URI and "From" header URI will be dropped The question is, what about messages that do not enter either of the two conditionals? For example, I expect the following to be very common: * Method: INVITE * R-URI: myself * From: username@"UAC's local IP address" (not myself) * To: myself So in the example above, the auth route will return without either having challenged or dropped the request, am I correct? This is because: * For the challenge: Method is not REGISTER and "From URI" is not one of kamailio host's aliases (cumulatively) * For dropping after sending 403: "From URI" is not one of kamailio's host's aliases (which calculates to true) but R-URI is "myself" So I'm guessing we're expecting the challenge to come from elsewhere in cases like the example above? Or is there something else I'm missing here? Thanks! BR, George

is_first_hop
by Nicolas Breuer 02 Aug '17

02 Aug '17

Hello, I tried to understand the concept of first hop in "replies" In the documentation ; For incoming SIP replies, it means that top Record-Route URI is 'myself' and source address is not matching it (to avoid detecting in case of local loops).

SIP Proxy/Redirect
by Aaron Tecey 02 Aug '17

02 Aug '17

Hi All, Hoping for some help as a beginner. I need to configure a sip proxy server so that it redirects all processes to a freeswitch server on another network. SIP UACs are on an isolated network and have only a connection to the sip proxy. All I need the proxy to do is pass on all requests to the the freeswitch UAS on a different network, as it will handle registering etc. Is there a basic setup for this type of behaviour?

Reverse DNS lookups inside Kamailio
by Sebastian Damm 02 Aug '17

02 Aug '17

Hi, for a project I need the option to do a reverse lookup of an IP address and use the value from it in a variable. As far as I could see the ipops module only allows SRV and A record lookups. Is there anything I missed? And if there is nothing inside Kamailio, how could a good approach look like? Thanks in advance, Sebastian

T.38 fax, rtpproxy, re-invite
by Yu Boot 02 Aug '17

02 Aug '17

Hello. I'm using almost default kamailio.cfg with nathelper, rtpproxy, PSTN dialing and other default features. I have following scheme: FXS gateway -> (NAT) -> Kamailio -> FreeSwitch Voice calls work perfectly, no one-direction sound and so on. But with fax machine there was a problem. In wireshark I saw UDPTL from FS to Kamailio IP, and no UDPTL at all to FXS gw. I've guessed that something's wrong with a re-INVITE request processing in Kamailio. I've added this to WITHINDLG route: else if ( is_method("INVITE") ) { record_route(); } And problem was magically solved, T.38 now works OK. Is this OK solution or this may break something elsewhere? Thanks.

Usleep on Reply
by Nicolas Breuer 01 Aug '17

01 Aug '17

Hello All, I'm trying to code something on the on_reply part to do something if I receive a 183 ( Session in progress ) , followed immediately by a "180" I tried to sleep 1 second the 183 and recheck if I received before a 180 but seems the "sleep" function sleeps everything ( also the received 180 ) Is a developper can confirm that ? The goal is to detect if a 180 follow the 183.

Hi All, I have a setup with two kamailio v5.0 and a load balancer(keepalived) It seems to check the heath of kamailio server load balancer establishing the tcp conneciton and resetting the connection once its got established. and due to resetting the connection I keep on getting following log message.

uac_auth credentials
by Volkan Oransoy 01 Aug '17

01 Aug '17

Hi all, I use UAC module for remote registrations on my proxy box. There is no problem with incoming calls and I successfully register and receive calls. I have a Freeswitch box behind this proxy box and I want my proxy to add authorisation headers for outgoing calls transparently. I already have credentials at uacreg table for remote registrations. Is it possible use same credentials at uac_auth() function? Or should I run SQL to retrieve necessary fields to feed uac_auth? Thanks! /Volkan

Need help to log the call trace/flow in file
by amit Kumar 01 Aug '17

01 Aug '17

Hi Developers, I need help to log the call flow in a file. Our purpose to have only one entry per call in a file based system at the end of the call. For example: CALL-ID TO FROM START TIME END TIME .... MISSED COMPLETED 1 sip:1@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 yes no 2 sip:2@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 no yes 3 sip:3@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 no yes I have gone through various trace module, but its appear that all module record the call flow/logs in database. ie siptrace,acc,dialoge module. Could you please help me to log the information. one of the approach I have thought to store all the variable in AVP variables in request_route,failure_route,on_reply route..etc For ex. $avp(from)=$fu; $avp(to)=$tu; $avp(starttime)=startime $avp(endtime)=endtime etc... //log at call end in a seperate logs file and xlog("LOG_INFO",$avp(from),,$avp(to),$avp(starttime),$avp(endtime)) Please let know if this approach is correct or any other way to achieve this, Thanks, Amit

Weird issue with kamailio relaying messages to itself
by George Diamantopoulos 31 Jul '17

31 Jul '17

Hello all, I have been toying with kamailio lately, and I thought I had gotten to the point where I had a mostly working (tm) prototype. I gave it a test drive with some real calls, however, and an issue manifested at least once, where homer received packets originating from the kamailio host, and whose destination was also the kamailio host. The dialog this manifested in is a generally problematic one, with many retransmissions occurring because of slow database access (I haven't implemented htable caching yet). No packet capture over the network is actually taking place, I'm copying everything to homer with "trace_mode"set to 1. Homer shows these messages like in the screenshot: https://imagebin.ca/v/3VGJAmovRBmo. Here's an example of a packet: 2017-07-28 14:32:29 +0300 : 2.3.4.5:5060 -> 2.3.4.5:5060 INVITE sip:1234567890@kamailio-server.org SIP/2.0 Record-Route: <sip:2.3.4.5;lr;ftag=as491cec82> Via: SIP/2.0/UDP 2.3.4.5;branch=z9hG4bK0cf.07799e3eb71f33a9ef91178ac760ebd2.0 Via: SIP/2.0/UDP 2.3.4.5;branch=z9hG4bKsr-BnCVyrWoUladI14pU7Pry-Pzy-ONy-VSQ74NU7HzeYazq2nFU2Oc5FIWiGIKq-HXex1oONpam-C6IrIXkr4FQxZRh7sM Max-Forwards: 69 From: <sip:subscriber@5.4.3.2:5061>;tag=as491cec82 To: <sip:1234567890@kamailio-server.org> Contact: <sip:2.3.4.5;line=sr-eNC05xhKefQnON1EglFrOkF0OfpzV2s9UzM9UXMNQXMn5-B0Q-s*> Call-ID: 4e5d22c3369704b97d866c8d0f3798f8@192.168.201.2:5061 CSeq: 103 INVITE User-Agent: Asterisk PBX 11.13.1~dfsg-2~bpo70+1 Date: Fri, 28 Jul 2017 11:32:24 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Remote-Party-ID: "9876543210" <sip:9876543210@192.168.201.2 >;party=calling;privacy=off;screen=yes Content-Type: application/sdp Content-Length: 500 v=0 o=root 242468242 242468243 IN IP4 172.17.130.13 s=Asterisk PBX 11.13.1~dfsg-2~bpo70+1 c=IN IP4 172.17.130.13 t=0 0 m=audio 59426 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:50 a=sendrecv a=rtcp:59427 a=ice-ufrag:hffIoy6x a=ice-pwd:nXB8ip7Qz8ZG5yyZRr97kGJbej a=candidate:igct4zWHEzhGCjWc 1 UDP 2130706431 172.17.130.13 59426 typ host a=candidate:igct4zWHEzhGCjWc 2 UDP 2130706430 172.17.130.13 59427 typ host Can something like this be triggered by misconfiguration in the routing scripts? Should it worry me and should I dig into it more? Could it be a bug of the siptrace module and nothing bad actually took place? I'm not sure where to start with this, so any input would be greatly appreciated. Thanks!

Rate limiting
by NITESH BANSAL 31 Jul '17

31 Jul '17

Hello, I plan to add some rate limiting in the Kamailio. I'm already using Pike to rate limit based on the source IP. But in this case, i want to do the rate limiting per customer(regardless of the source IP), I can identify the customer based on a custom header in the INVITE, idea is to limit the customer to 'x' number of requests per second.

Configuration to use rtpengine for SRTP
by David Cunningham 31 Jul '17

31 Jul '17

Hello, We're configuring Kamailio 4.2 with rtpengine to act as a midpoint between a telephone using TLS/SRTP and Asterisk. There are examples out there for TLS/SRTP with WebRTC, but we're using a plain hard phone, not WebRTC. Would anyone be able to point us towards a Kamaiio configuration which: a) Tests if the destination phone (stored using usrloc) uses TLS. b) Sends RTP for calls to a TLS phone to rtpengine to be encrypted. We can assume all phones using TLS want to use SRTP. Thanks very much in advance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 Australia: +61 (0) 2 8063 9019

why is tcp_no_connect disabled by default
by Vik Killa 27 Jul '17

27 Jul '17

I'm trying to understand the scenario when `tcp_no_connect` should ever be set to `no`. Kamailio comes with `tcp_no_connect=no` by default which means it will try (and seemingly always fail) to create an outbound tcp connection when a UAC's tcp connection is lost. This in-turn could start building up the tcp write queue and can be disastrous at scale. So why would this setting (`tcp_no_connect=no`) ever be useful? Thanks

Re: [SR-Users] kamcmd uac commands not working
by Gertjan Wolzak 26 Jul '17

26 Jul '17

Hello Daniel, Yes, that are the parameters I've set. But just found out why the kamcmd uac commands were not working. Looks like you have to have a succesfull registry to be able to give the uac.reg_xxx command. Once I had a succesfull registration, the command works. So, I will continue to learn.. Thanks.

Fwd: kamcmd uac commands not working
by Gertjan Wolzak 26 Jul '17

26 Jul '17

Hello All, Been a while, glad to be back. I started working with the kamailio 5.0.2 version, specificly with the UAC module trying to register accounts with another B2BUA. When I give the command kamcmd, I end up in de kamcmd cli. The command ctl.connectsion shows me the number of connections, when I give the command uac.reg_dump, the result is an error: 500. Below the cli dump... I'm going to assume I have an error in my config, but I don't understand where... I've looked at the uac module documentation and think I have set the parameters correctly. kamcmd 1.5 Copyright 2006 iptelorg GmbH This is free software with ABSOLUTELY NO WARRANTY. For details type `warranty'. kamcmd> ctl.connections 1 kamcmd> uac.reg_dump error: 500 - command uac.reg_dump not found kamcmd> # Uac parameters modparam("uac","restore_mode","auto") modparam("uac", "restore_dlg", 1) # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # default retransmission timeout: 30sec modparam("tm", "fr_timer", 30000) # default invite retransmission timeout after 1xx: 120sec modparam("tm", "fr_inv_timer", 120000) # ----- rr params ----- # set next param to 1 to add value to ;lr param (helps with some UAs) modparam("rr", "enable_full_lr", 0) # do not append from tag to the RR (no need for this script) modparam("rr", "append_fromtag", 1 # Dialog parameters modparam("dialog", "enable_stats", 0) modparam("dialog", "db_url", DBURL) modparam("dialog", "dlg_flag", 4) Does anyone see an error I've made, or has some information for me to look at...? Or maybe I did not provide enough information... Tips would be appreciated. Rgds, Gertjan

xavp questions (variables in root/branch)
by Vasiliy Ganchev 25 Jul '17

25 Jul '17

Hi, community! I have a question regarding xavp usage. according to docs, xavp has format: $xavp(root=>branch)="value"; I want to use "root" and "branch" - variables. (as it is implemented with AVPs - the id there, can be variable) e.g.: ... $var(root_key) = "root_1"; $var(branch_key1) = "key_value1"; ... $xavp($var(root_key)[0]=>$var(branch_key1)) = "some_value"; ... Playing around with the script - I found that it is currently impossible (tested with 4.2.5 and 5.2.0 versions). Kamailio interprets variables in "root" and "branch" as static strings. Walking through the mailing list history, I have an impression that xavp are originally designed to operate only with constant keys. The question is: is it planned to add functionality with variables as "root" and "branch" components? Thanks in advance for the answers! Best regards -- View this message in context: http://sip-router.1086192.n5.nabble.com/xavp-questions-variables-in-root-br… Sent from the Users mailing list archive at Nabble.com.

I_SCSCF_select function dont return the next SCSCF in IMS network!!!
by Mojtaba 25 Jul '17

25 Jul '17

Hello, Today i have a strange problem in IMS network. All nodes (pcscf,icscf,scscf and hss) are configured in independent server. My domain is default(open-ims.test) Now when i want to register bob(a)open-ims.test, I get this error from ICSCF: 500 Error in request. When i saw the log files, i found the icscf could not found the next node(scscf) in registration path. As i defined prefered scscf_uri in configuration file, Why the icscf, could not found the scscf? The dns server works correctly and i have ping of scscf.open-ims.test from icscf node. When i trace the diameter packets, the icscf connect to hss successfully but dont send UAR to hss while registration proccess!! It's strange. Please let me know why i have this problem, Thanks With Regards. -- --Mojtaba Esfandiari.S

TR: Failure Mode
by Nicolas Breuer 24 Jul '17

24 Jul '17

Hello, Some help here is needed # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) I test a call with two branches. 1st branch received a 408 timeout error 2nd branch received a 486 busy. Normally the failure route should be with the 486. NOTICE: <script>: Failure route -----2---1--408---- We can see the 408 is the winning reply but I understood from the documentation that if Failure reply mode is "3" , the winning reply is always the reply from the last branch :) It's a problem because if the 1st is timeout (because down), the second is OK but callee is busy ; we don't send the right reply to the caller

path use_received not working?
by Iskren Hadzhinedev 23 Jul '17

23 Jul '17

Hello, I have a kamailio proxy in front of FreeSWITCH. Whenever FreeSWITCH initiates the dialog (e.g. sends an INVITE), kamailio doesn't use the 'received' parameter and it forwards to the RFC1918 IP address. The initial INVITE from FreeSWITCH has the following headers: To: <sip:1001@192.168.1.200:5063> Route: <sip:1.2.3.4>;lr;received=sip:5.6.7.8:5063 Where 1.2.3.4 is the kamailio public IP and5.6.7.8 is the public IP of the UAC behind NAT. I have modparam("path", "use_received", 1) in my config file and to my understanding that should be sufficient to route to the proper IP, but kamailio keeps sending INVITEs to 192.168.1.200. Can anyone tell me what am I missing? Thanks! Kind regards, Iskren

Re: [SR-Users] Problem with IPv4-IPv6 media bridging using RTPengine

The UDP protocol of the rtpproxy module should work with rtpengine, but not many people are using it, so it's always possible that some bugs creep in. I'll look into it anyway, but in the long run, it's much preferable to switch to the rtpengine module. Cheers ########################## Hello Richard, thank you very much for your answer. I will try to use rtpengine module. As I can see from logs, kamailio is sending correctly data to rtpengine but rtp engine failed to parse IPv6 address from SDP body. I'm sending flags to rtpengine according to the howto from link I've posted in the original post. This is the part of the config: if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB) || isbflagset(FLB_V4V6))) return; if(isbflagset(FLB_V4V6)) { if(af==INET6) { rtpproxy_manage("FAEI"); } else { rtpproxy_manage("FAIE"); } } else { if(af==INET6) { rtpproxy_manage("FAEE"); } else { rtpproxy_manage("FAII"); I'm not sure if I need to inform rtpengine that in SDP body will be IPv6 address.

kamailio 5.0 with asterisks
by Aidar Kamalov 20 Jul '17

20 Jul '17

Hello! I'm new with kamailio, so may be don't understand some basic. I'm tryin to load balance asterisk servers with kamailio and dispatcher module. My ip phones registered at kamailio, for example: [root@sipchel ~]# kamctl ul show 101 { "jsonrpc": "2.0", "result": { "AoR": "101", "Contacts": [{ "Contact": { "Address": "sip:101@192.168.2.62;line=4733c4bfa459eea", "Expires": 2953, "Q": -1, "Call-ID": "1361221648", "CSeq": 136, "User-Agent": "Linphone/3.6.1 (eXosip2/3.6.0)", "Received": "[not set]", "Path": "[not set]", "State": "CS_SYNC", "Flags": 0, "CFlags": 0, "Socket": "udp:192.168.10.54:5060", "Methods": -1, "Ruid": "uloc-596f5abc-2ce5-2", "Instance": "[not set]", "Reg-Id": 0, "Last-Keepalive": 1500530337, "Last-Modified": 1500530337 } }] }, "id": 15024 } I have realtime asterisk server. [root@sipchel ~]# kamctl dispatcher dump { "jsonrpc": "2.0", "result": { "NRSETS": 1, "RECORDS": [{ "SET": { "ID": 1, "TARGETS": [{ "DEST": { "URI": "sip:192.168.4.16", "FLAGS": "IX", "PRIORITY": 0 } }, { "DEST": { "URI": "sip:192.168.10.47", "FLAGS": "AX", "PRIORITY": 0 } }] } }] }, "id": 15087 } So I want if 101 call to 102 it will process by asterisk(for call recording and other features). Now if I call from 101 to 102 kamailio will forward to asterisk and asterisk dialplan cannot find that extesion(as expected, because it is not registed on asterisk) [kamailio] exten => _1XX,1,Dial(SIP/${EXTEN}) exten => _1XX,n,Hangup If I change dialplan to Dial(SIP/KAMAILIO/${EXTEN}) call wil return to kamailio, but kamailio send it back to asterisk... I hope I explained correctly, my English is terrible. Is my screnario proper? How this usually done? Should I forward sip registrations to asterisks?

Hi, I'm trying to integrate Google cloud speech recognition v2 in it. I can get the audio recorded, have created Service key and API key but whenever I try to access it, I just get 403 access denied. I am at my wits end here. Has anybody tried it ? were you successful ? Could you please guide me how to do it ? I'll be grateful to you if this works ! -- Warm Regds. MathuRahul

Problem with IPv4-IPv6 media bridging using RTPengine
by Ismir Saljic 19 Jul '17

19 Jul '17

Hello, I've issue with bridging media between IPv4 and IPv6 clients. IPv4-IPv4 and IPv6-IPv6 calls are working without issues. I'm using kamailio 4.4.2 and configuration according to: http://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 SIP signalling is working without issues,but media addresses in SDP are not rewritten correctly. The server is on amazon AWS and both kamailio and RTPengine are on the same server. RTPengine is running using these options: /usr/sbin/rtpengine --interface=privateIPv4!publicIPv4 --interface=GlobalIPv6 --listen-udp=127.0.0.1:22222 --tos=184 --pidfile=/var/run/rtpengine.pid --log-level=6 --log-facility=daemon In case of IPv4-IPv6 call, INVITE message contains correct IPv4 address but 200 OK response to the caller still contains IPv6 address of the callee in SDP body instead of IPv4 address of the server/RTPengine. This is the log during generation of the 200 OK response. Seems that RTPengine failed to parse IPv4 address from SDP body.

dns failover and branches
by Juha Heinanen 19 Jul '17

19 Jul '17

If Request-URI hostpart is a domain name with more than one SRV record, it appears that each SRV destination creates its own Kamailio branch. If branch route is set before t_relay(), it is executed only on the first SRV destination. If the first SRV destination fails, Kamailio tries automatically the second one, but any branch flags set in the branch route are lost. What is the simplest way to make Kamailio preserve the stuff set in the branch route for all SRV destinations? -- Juha

about rtpengine-[offer-answer] via-branch flag
by Juha Heinanen 18 Jul '17

18 Jul '17

rtpengine-offer function documentation tells this about via-branch flag: via-branch=... - Include the “branch” value of one of the “Via” headers in the request to the RTP proxy. Possible values are: “1” - use the first “Via” header; “2” - use the second “Via” header; “auto” - use the first “Via” header if this is a request, or the second one if this is a reply; “extra” - don't take the value from a header, but instead use the value of the “extra_id_pv” variable. This can be used to create one media session per branch on the RTP proxy. When sending a subsequent “delete” command to the RTP proxy, you can then stop just the session for a specific branch when passing the flag '1' or '2' in the “rtpengine_delete”, or stop all sessions for a call when not passing one of those two flags there. This is especially useful if you have serially forked call scenarios where the RTP proxy gets an “offer” command for a new branch, and then a “delete” command for the previous branch, which would otherwise delete the full call, breaking the subsequent “answer” for the new branch. Is the note about "serial forking" correct or should it be about "parallel forking" instead? In case of serial forking, it would not matter if the whole call is deleted, because a new offer would be issued for the next branch. Or perhaps I just don't understand the meaning of the note? -- Juha

rtpengine: Failed to open UDP control connection port
by David Cunningham 17 Jul '17

17 Jul '17

Hello, We're using Kamailio 4.2.1 with rtpengine 5.1.2.1 on Ubuntu 16.04. When running rtpengine we get this error: [1500263405.711288] ERR: FAILED TO CREATE KERNEL TABLE 0 (File exists), KERNEL FORWARDING DISABLED [1500263405.712367] CRIT: Fatal error: Failed to open UDP control connection port The first line I think is not important, but the second appears to be. It's being run as root with these options: /usr/sbin/rtpengine --interface=xx.xx.xx.xx --listen-ng=7724 --timeout=60 --silent-timeout=3600 --pidfile=/var/run/rtpengine.pid --port-min=45000 --port-max=50000 --table=0 Running "netstat -lnp | grep 7724" does not report anything listening on port 7724 already. Has anyone any ideas? Thanks in advance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 Australia: +61 (0) 2 8063 9019

Kamilio new user - help get going
by Kenneth Knudsen 17 Jul '17

17 Jul '17

Hi I have been watching numerous videos on youtube in search of how to configure Kamilio ! I know we I need the Sip Server, but don't know how to get it configured. The installation is obvious with the commands as a root user. Brief description of the project: Have quite a few customers we want to move from PSTN (AT&T primarily) to a Voip/Sip solution. So instead of setting up 1 FreePBX and 1 public ip, we would rather use 1 public IP to many FreePBX servers on the backend. I haven't been able to find one video on how to configure this SIP server, and was hoping somebody here might have some clues to lead me in the right direction. I found one company that would help us, but they said at least 20 hours just to configure the first customer/freePBX installation. If we could get help setting up the first we should be able to figure out the ones to come later. Any help would be appreciated... We know the product is awesome, we have the keys but don't know how to run the thing or even get it started !! Kind regards, Kenneth Knudsen

Clarification on redis_cmd in ndb_redis module
by vivek＠advaitamtech.com 17 Jul '17

17 Jul '17

Hi, Am using redis_cmd in kamailio.cfg to perform redis operations. I would like to know if redis_cmd() creates new connection everytime I call it in kamailio.cfg?. Since am using redis_cmd() multiple times to access few data's. Also, is calling redis_free() necessary to avoid connections being open? I am facing an error of number of open files exceeded. This error is caused by ndb_redis module. But cannot confirm due to which part of redis. Thanks, Vivek

Need help to send INVITE to multiple client based on REGISTRATION status
by amit Kumar 15 Jul '17

15 Jul '17

Hi All, Following are the requirement which we want to achieve through Kamailio. Our "voip client" will not be register in advance.When Kamailio get INIVITE request for particular "voip client"(multiple client), we send push notification to make "voip client"(multiple client) alive and get it register for to Kamailio. Meanwhile INIVITE request will wait. the moment, "voip client" get register, Kamailio will send INIVITE to all the client despite their *registration time/status*.for example - if first client get register with in T+1 second,that should also get INVITE and another client get register in T+2 second that should also get INVITE. Could you please help me if this is possible in Kamailio. I have done some code walk through and have the basic idea to save the INVITE transaction(similar to suspend and continue), later point of time when i get the register request, I will use functionality like t_lookup_request and and lookup(which in turn append_branch) and call the t_realy () again. Please let me know if this is correct approach or if there is some other way to solve this. Thanks, Amit

What happens to calls when Kamailio restarts?
by Samuel F. 13 Jul '17

13 Jul '17

Hi, I have a question regarding calls and Kamailio restarts. Suppose Kamailio crashes (and started again), is restarted or failed over to a different server (same IP). What then happens with calls? Let's suppose the following scenario: - 1000 calls active on the machine - Some are in call setup, some are in call, some are in teardown phases - The proxy is stateful - The proxy forwards calls from B2BUA machines to an ITSP (outbound only) - Uses record-routing - Uses loose routing What will be the likely outcome of the restart with regards to the calls in the different phases and accounting for said calls? All the best, Samuel

New Diameter IMS Module : can we use it as SWx interface
by Igor Potjevlesch 11 Jul '17

11 Jul '17

Dear Kamailio users, Recently has been added to Kamailio two new modules : CDP and CDP_AVP There is not the TS 29.273 in it but I wanted to know if we can use it to emulate SWx interface? or add it with a non-hardcoded solution? I have seen the kamailio conference online and one session told about emulate IMS HSS with those two modules. Is someone tried to do it and want to share is experience with me ? Some DIAMETER functions in these modules are closed from the SWx.

Siremis updates
by Daniel-Constantin Mierla 11 Jul '17

11 Jul '17

Hello, there is some ongoing work on Siremis (web management interface for kamailio) to make it fully compatible with Kamailio 5.0.x as well as update some of its legacy components: - https://github.com/asipto/siremis So I thought to start a discussion here and see if some of those changes are going to impact too much existing installations or what are the best options to use for the future. Done so far: 1) implemented the JSONRPC client using UDP and unix domain sockets, to work in pair with jsonrpcs module as a replacement for removed MI interface. The old JSONRPC over HTTP is still an option. 2) charts system has been migrated from open flash chart (ofc) to echarts (pure html5/javascript) -- therefore no more requiring to enable flash in browser. Configuration is the same and the charts should look pretty similar. If you upgrade, apart of different html view for the charts, the config files should not be changed. If you notice something broken, open an issue on github project linked above. Planned to be done: 3) Relocate siremis/modules/ser to siremis/modules/sipadmin -- this purely for more suggestive name for the admin module related to the SIP services offered by Kamailio, and be in pair with the module sipuser. This is mainly search and replace over php and xml files, however, it is going to impact if you developed your own internal extensions for siremis and placed them in the 'ser' module. It will require that you do the same search+replace 4) Review existing database tables views and add fields for missing columns. 5) Add views for other database tables. First in my mind being the table for rtpengine module. If you use some modules with tables not yet managed by siremis, reply and list them to set a list of priorities. Should have other things to report about siremis and are not yet listed on project's issue tracker, let's discuss here. Testing and feedback for 1) and 2) are very appreciated! Cheers, Daniel -- Daniel-Constantin Mierla www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - www.asipto.com Kamailio World Conference - www.kamailioworld.com

domain vs uid_domain module
by Huber Andreas 10 Jul '17

10 Jul '17

Hi, I was comparing the documentation of the "uid_domain" and "domain" modules and I was wondering what is the main difference between the two modules. While the "uid_domain" module has more documentation, it seems to me that both modules are offering very similar functionality, or am I missing something ? Also I found it curious that the documentation of the "uid_domain" module uses "domain" as the module name in all its examples for the module configuration. E.g. modparam("domain", "domain_table", "new_name") But when I try to use the "uid_domain" module, I actually have to specify the parameters as : modparam("uid_domain", "domain_table", "new_name") The same question also applies to the "uid_auth_db" module that resembles closely the "auth_db" module in the documentation, but not in the implementation. Kind Regards, Andreas

app_lua reload - what exactly gets reloaded?
by Sebastian Damm 10 Jul '17

10 Jul '17

Hi, we have written some logic for a project in lua. There is a small function that gets called from Kamailio, but the main logic is done in a self-written module. That module does initialize some values from database on the first request that comes in. Now when reloading app_lua from kamcmd or via jsonrpc, I don't see the log output generated when initializing. In the debug log, I can see that the reload is taking place, but the variables and state seem to not get reset. What does the reload command actually reload? Best Regards, Sebastian

Reload an individual entry into a hash table from database
by Jonathan Hunter 05 Jul '17

05 Jul '17

Hi Guys, We are currently building a wholesale platform to route numbers to particular carriers, and we are looking to do this with hash tables. We will potentially have 100s of thousands of numbers we will need to lookup and query as to where to route them, and one idea is to populate them in a database, we would then load these values into a hash table which will be defined in the kamailio configuration file for us to query in realtime when an Invite arrives. The backend database will be modified constantly, so we would have the need to reload the hash table on demand. I can see there is the ability to reload a whole hash table, sht_reload, but is there an option to reload for an individual entry which has been added to the database, and we therefore want it in the hash table? I dont see anything in documentation (forgive me if I have missed it), is there an option to reload just an individual key entry from the database into cache? Thanks Jon

Re: [SR-Users] host to get name of local server

I haven't looked at its implementation, so be careful if it does DNS (or system call) query every time it is used, it may slow down the processing, in that case you can just store in another variable and use it instead.

host to get name of local server
by Henry Fernandes 05 Jul '17

05 Jul '17

We have multiple Kamailio 4.4.x servers and I am setting up stats tracking. I would like to track the stats for each individual Kamailio server separately like so: kamailio_1.sip.register.count kamailio_2.sip.register.count kamailio_3.sip.register.count The problem is that we use one common file (in version control) for our Kamailio configuration. Thus, I can’t just hardcode the hostname into the file because it will be the same for each server. Does anyone have a solution for me? Is there a variable that provides the hostname or is there something else I can do? Ideally, I’d love to be able to do something like this. statsd_incr($host_name + “.sip.register.count");

kamcmd dialogs count
by Arek Łazarczyk 05 Jul '17

05 Jul '17

Hi, I have a problem with kamcmd, for now i use kamctl fifo profile_get_size to get dialogs count to pass to nrpe and futher to nagios. Since fifo is deprecated, and i want to migrate to kamailio v5.0, i must change my method of counting dialogs to kamcmd dlg.profile_get_size. Problem is that i have dialog profiles values starting with 0, so kamctl fifo profile_get_size caller 004 returns correct vaule, but kamcmd dlg.profile_get_size caller 004 returns 0, i think that kamcmd converts 004 to just 4 on fly. Is there any way to prevent such behavior ? Thx4help in advance. Best regards, AŁ.

Dear Expert Fellows,Good Day, I'm wonder whether kamailio developed an open source based LTE HSS handles both IMS and LTE procedures "LTE Attach, Location Update, Authentication, ....". If it's not yet developed, is there any plan for it in the near future. Thanks and have a nice day. Ibrahim Almahi966594996362

missing request username on register
by 赵国杰 04 Jul '17

04 Jul '17

Hello all, I have two kamailio servers(A and B) with exact same config using the same mysql db. I can register to A but not B. Server B complained: ERROR: <script>: fu is sip:851968556538527744@104.198.52.31, ru is sip:104.198.52.31, rU is <null> After capture the udp packet on both server using ngrep, the REGISTER they received are both good except A returns 200 OK and B returns 403 Not relaying. I don't have a clue what went wrong. How come the $rU is null when all the headers in REGISTER are valid? Can someone please point me the direction? Thanks Jesse

contact issue on kamailio with sipml/jssip over wss
by David Villasmil 04 Jul '17

04 Jul '17

Hello guys, So i've setup kamailio 5 with wss. Registration goes ok, but when trying to call, SIPML as well as jsSIP send garbage as Contact header, something like: Contact: <sip:0ku6du26@7j65fcf53i2k.invalid ;transport=ws>;reg-id=1;+sip.instance="<urn:uuid:8b49ac42-2039-4122-9f5b-6f4e9f471f52>";expires=600 so when it passes through: if (is_method("REGISTER")) { fix_nated_register(); } else { if (!add_contact_alias()) { xlog("L_ERR", "Error aliasing contact <$ct>\n"); sl_send_reply("400", "Bad Request"); exit; } } (taken from several examples i've found around) add_contact_alias() fails because it tries to find whether the ip address in the contact header is different from the received ip, and if not, it adds the received ip as a parameter... so the call doesn't work... I assume there's a way around this, can anyone help? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

Using lock() correctly
by Sebastian Damm 03 Jul '17

03 Jul '17

Hi, for a project I need to make sure, I have a setup where I get mirror-traffic into Kamailio which has to do something with it. To work correctly, I need to make sure, the initial INVITE is processed correctly before any reply to the same call. So I thought I use lock() and unlock() for it. This is what the relevant kamailio.cfg part looks like: request_route { xlog("L_INFO", "Got new packet $rm: $si => $Ri\n"); route(li); } onreply_route { xlog("L_INFO", "Got new packet $rm: $si => $Ri - Reply Code $rs\n"); route(li); } route[magic] { lock("$ci"); xlog("L_INFO", "Obtained lock, calling lua...\n"); if(!lua_run("handle_packet")) { xlog("L_ERR", "SCRIPT: failed to execute lua function!\n"); } unlock("$ci"); xlog("L_INFO", "Lua finished, released lock...\n"); drop; exit; } And this is what the log says: Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: <script>: Got new packet INVITE: 172.20.21.247 => 172.20.21.4 Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: <script>: Obtained lock, calling lua... Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: app_lua [app_lua_sr.c:98]: lua_sr_log(): some logging Jun 28 13:27:04 busch /usr/sbin/kamailio[18837]: INFO: <script>: Got new packet INVITE: 172.20.21.4 => 172.20.21.247 - Reply Code 407 Jun 28 13:27:04 busch /usr/sbin/kamailio[18837]: INFO: <script>: Obtained lock, calling lua... Jun 28 13:27:04 busch /usr/sbin/kamailio[18837]: INFO: <script>: Lua finished, released lock... Jun 28 13:27:04 busch /usr/sbin/kamailio[18836]: INFO: app_lua [app_lua_sr.c:98]: lua_sr_log(): some more logging As far as I understand the documentation, the second packet should wait for the lock on the Call-ID before executing the lua function. So process 18836 should finish its lua execution before 18837 can do anything further. Did I completely misunderstand the lock() function? I'm using Kamailio 5.0.2. Thanks for helping me understand what Kamailio is doing here. Best Regards, Sebastian

drouting / do_routing / prefix unknown
by Jean Cérien 03 Jul '17

03 Jul '17

Hello I am using Kamailio 5.0.2, with module drouting to do prefix based routing. 1. When I call do_routing and the prefix is not known, the r-uri remains unchanged. Is there a way to detect that the prefix is unknown, other than r-uri remains unchanged ? 2. I have the following parameters modparam("drouting", "db_url",DBURL) modparam("drouting", "sort_order", 0) modparam("drouting", "use_domain", 0) modparam("drouting", "force_dns", 1) # modparam("drouting", "enable_keepalive", 1) If I enable keep alive, I get the following error: Jun 20 22:37:17 kamailio1 kamailio: ERROR: <core> [core/modparam.c:141]: set_mod_param_regex(): parameter <enable_keepalive> of type <2> not found in module <drouting> yet, the documentation leads me to think that it should work: *NOTE: this option is only compatible with <em>sort_order</em> 0 currently. With sort_order value of 1 or 2, destinations status will simply be ignored.* Thanks for your help J.

call forward on no answer
by frédéric Gaisnon 03 Jul '17

Hello, In my Platform i have a kamailio used as pseudo SBC and a kamailio used as Proxy (AS trigger) (cpl are applied on this instance). When I make a call and callee doesn't answer that call my SBC detects the timeout and generates a 408 to Proxy (according to fr_inv_timer) , but it generates CANCEL too. Is it possible to deactivate these CANCEL? if not what is the configuration in order to be able to trigger CFNA? Regards, Frédéric

remote ip address of sender and receiver

Hi, all Is there any way to get remote ip address of both sender($si) and receiver(?)? I am configuring kamailio with multiple rtpproxy sets. Basically, rtpproxy set will be choosed based on the country those ip addresses of caller and callee belong to. Lets say if caller and callee are both in US, set 1 will selected. If they are not in the same country, set 2 will be selected. I dont know if there is any way to do that. Best regards Fisher

IOS 10 and SIP
by Kjeld Flarup 01 Jul '17

01 Jul '17

Rumours is that Apple no longer accepts apps which can do persistent connections in the background. To my best knowledge that means that IOS no longer supports SIP incoming calls. The app should now use Push Notifications, but SIP does not support this. Anybody faced this problem? Is the solution to call an external program when processing an Invite? This leaves some issues. 1. Should we wait some seconds before proceeding or wait until the Push notification has been processed, to give the app time to register. We cannot start to send invites, before we have a correct registration. An old registration may change ports when the app wakes up and makes a new register via NAT. 2. How do we know, if a given user should have a push notification? 3. Which information do we need to be able to send the push notification? 4. Does this give a penalty to Android users, because we have to wait for IOS? -- Med venlig hilsen / Best regards Kjeld Flarup (Christensen) M.Sc E.E, Teknisk chef Viptel ApS, Hammershusvej 16C, DK-7400 Herning Telefon: +45 46949949, Telefax: +45 46949950, http://viptel.dk

[mohqueue] MOH service / A case with MOH queue
by Issam Hambouz 30 Jun '17

30 Jun '17

Hello! I am exploring mohqueue module and have few questions: - Could it be used to provide MOH service for SIP endpoints? I am aware that its main functionality is to queue calls (along playing a MOH for queued calls) and provides a mechanism to retrieve calls (FIFO), but I had the impression, reading several emails in this group, that it can be used in a way to provide MOH whenever a call is put on-hold -- I tried to use it with the re-INVITE received when a call is put on-hold, but got a log message stating that it works with initial INVITEs only (something like that) - On a test setup (Kamailio 4.2.3 / 2.0.0), I was able to reach the queue / listen to the MOH but encountered a strange case where the call gets automatically removed from the queue after 4-5 seconds (can be seen removed from kamailio.mohqcalls as well) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): mohq_process: Processing INVITE, queue (demo) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): create_call: Added call (<sip:6010@10.110.3.57>;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47) to queue (demo) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): first_invite_msg: Making offer for RTP link for call (<sip:6010@10.110.3.57 >;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): first_invite_msg: Sent RINGING for call (<sip:6010@10.110.3.57 >;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): send_rtp_answer: Answering RTP link for call (<sip:6010@10.110.3.57 >;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): start_stream: Starting RTP link for call (<sip:6010@10.110.3.57 >;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47) Jun 12 22:58:30 - DEBUG: mohqueue [mohq_funcs.c:2369]: mohq_debug(): send_rtp_answer: Responded to INVITE with RTP for call (< sip:6010@10.110.3.57>;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47) Jun 12 22:58:35 ERROR: mohqueue [mohq_funcs.c:1243]: invite_cb(): invite_cb: INVITE failed for call (<sip:6010@10.110.3.57 >;tag=c97a6b26-2bfe-4271-9db1-cee38ea96c47)!

Add extra headers on HTTP requests in Kamailio v5
by Joel Serrano 30 Jun '17

30 Jun '17

Hi all, Is there a way to add extra headers with http_client_query() from http_client module? In current http_query() from utils module, according to the doc, you can add a custom header: *4. Functions* *4.1. http_query(url, [post-data], [header-data], result)* *...* *If you want to add additional headers to the request, you have to define the “header”-data, that should be submitted in that request as the third parameter. If this parameter is empty, it is not set.* *...* and I have that working with the following: http_query("https://example.com/api", "param1=value1&param2=value2", "Cookie: apikey=super_secret_api_key", "$var(call_info)"); The problem is that http_query() is removed in Kamailio v5, and the http_client_query() only has the ability to add specifically the content-type header: *4. Functions* *4.1. http_connect(connection, url, [content_type, data,] result)* *...* *content_type - Used only when posting data with HTTP POST. An Internet Media type, like "application/json" or "text/plain". Will be added to the HTTP request as a header.* *...* Is there another way to add a custom header to a http request with the http_client module? Any workarounds for this? Thanks, Joel.

Segfault on kamailio 5.0.2. Suddenly stops processing traffic, then generates a core when restarting
by Joel Serrano 29 Jun '17

29 Jun '17

Hi all, I'm running into a weird situation with our newly deployed Kamailio servers. These servers are only doing SSL offloading and load balancing between another set of servers. Debian v9.0 + Kamailio v5.0.2 (from kamailio50 repository). After some time of running, kamailio suddenly stops responding to any request but the proccess is still alive. When we restart the service, a core is generated. I have opened an issue in GitHub: https://github.com/kamailio/kamailio/issues/1172 I'm attaching the backtrace here too in case anyone can take a look at it, unfortunately I'm lost right now. In dmesg I saw: [138953.744199] kamailio[12052]: segfault at 7efaf32f51b8 ip 00007efcf3b5df69 sp 00007ffe325dc0c0 error 4 in libcrypto.so.1.1[7efcf39f6000+265000] Thanks, Joel.

Hi to all I have the following scenario (Kamailio 5 and rtpproxy) *) Bob on a wifi network calls Alice *) During the call, Bob losts his wifi network (and so also changes his IP address) *) The RTP flow is interrupted With asterisk, disabling “Strict RTP” option, the flow does not interrupts: Asterisk detect the new IP address and sends the audio packets to the new IP address. It is possible to setup this behavior also with Kamailio? -- Emanuele Gambaro --- email: emanuele.gambaro(a)pynlab.com skype: sarbyn_work OpenPGP Key: https://goo.gl/fdeVnI

Question about sip call setup : three-way handshake
by Abdoul Osséni 27 Jun '17

27 Jun '17

Hello, During three-way handshake (SIP call setup - INVITE-200 OK - ACK) and before generating or sending the final 200 OK call, is there a way to confirm the caller is still available (no network issue)? I want to detect broken connections (ex. the uac uses 3G network) before generating/sending/forwarding the final 200 OK. Thanks. Regards Abdoul

How to forward DTMF (in RTP package) to conference within SEMS
by Nguyen Tran Nhan 27 Jun '17

27 Jun '17

I am using Kamailio + Sems + Rtpproxy for conference call. Once user join to conference, if user send dtmf, sems is detected but it does not forward DTMF (in RTP) to all user in conference. I think rtprelay_dtmf_detection should be configured? Do you have any idea to help? Thanks, Nhan

auth users using inmemory lookups
by Grant Bagdasarian 26 Jun '17

26 Jun '17

Hello, We're currently using the auth_db module and calling the function auth_check to check the Authorization header and authenticate the request. We moved most of our code to in-memory lookups (using htable), since we do not want our Kamailio servers to be DB dependent. Just to be sure, if we move the authentication to in-memory lookups we should use the auth module and call the pv_auth_check function instead right? The passwords in our users table are all stored in MD5, so we basically just have to put this table in a htable, and call the pv_auth_check and pass it the hashed password and the flag 1? Regards, Grant

Problem with t_relay() and VPN tunnel
by Carlos Ruiz Diaz 24 Jun '17

24 Jun '17

Hi, I have two SIP servers, *A* and *B*, connected each other though a OPENVPN tunnel. The server *B* needs to t_relay() every SIP message containing the method MESSAGE to the server *A* but these messages never reach destination. I have tested the tunnel connectivity and works fine. I wrote a Perl script (located in *B*) that sends SIP MESSAGES to Kamailio (located in *A*) trying to figure out what is happening but these messages are received by *A* and processed correctly but when *B* does the same from Kamailio, it is never received. Here is the route part of kamailio.cfg in *B*: Observation: ($rU == "1004") result is *true* * if(is_method("MESSAGE")) { if($rU == "1004") { xlog("L_INFO","En 1004"); rewritehost("10.8.0.1"); if (!t_relay()) xlog("L_INFO","MIO Error en t_relay"); t_reply("200", "Ok"); xlog("L_INFO","MIO despues rewrite"); exit; } .....* The perl script that WORKS: *$msg = 'MESSAGE sip:1004@192.168.1.2:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.1.2 From: "2002" <sip:2002@192.168.1.2 <sip%3A2002(a)192.168.1.2>>;tag=1837944796 To: <sip:1004@192.168.1.2 <sip%3A1004(a)192.168.1.2>> Call-ID: 19722852989(a)192.168.1.2 CSeq: 15773 MESSAGE Contact: <sip:2002@**PublicIP-protected**:5060> Max-Forwards: 29 User-Agent: DBL Content-Type: text/plain Content-Length: 34 +595981[protected] hello from kamailio '; use IO::Socket; my $sock = IO::Socket::INET->new( Proto=>'udp', PeerHost=>'192.168.2.102', PeerPort=>'5060'); print "Sending msg $msg\n"; $sock->send($msg) or die "error sending $!\n"; *Please help!

How to get the count of active calls handled in kamailio.
by vivek＠advaitamtech.com 23 Jun '17

23 Jun '17

Hi, I would like to know how many active calls are handled in kamailio server at a given point of time(concurrent calls). In the few older post it was mentioned to use "dialog" module for these statistics. In dialog module , there is a function called "active_dialogs" , which solves my requirement. But it is not clear how to use it. Can anybody help me out in this? Thanks, Vivek.

Kamailio v4.3.7 Released
by Daniel-Constantin Mierla 23 Jun '17

23 Jun '17

Hello, Kamailio SIP Server v4.3.7 stable release is out. This is a maintenance release of an old stable branch, 4.3, that includes fixes since release of v4.3.6. There is no change to database schema or configuration language structure that you have to do on installations of v4.3.x. Important note: unless some major regression is discovered in the near future, this is the latest release to be done from branch 4.3, which is no longer to be officially maintained. Therefore it is strongly advised to consider upgrading to 4.4.x or 5.0.x series. For more details about version 4.3.7 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2017/06/kamailio-v4-3-7-released/ RPM, Debian/Ubuntu packages will be available soon as well. Note: the latest stable branch is 5.0, at this moment with its latest release v5.0.2. See more details about it at: * https://www.kamailio.org/w/kamailio-v5-0-0-release-notes/ Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/miconda - http://www.linkedin.com/in/miconda

Releasing Kamailio v4.3.7
by Daniel-Constantin Mierla 23 Jun '17

23 Jun '17

Hello, I am planning to release Kamailio v4.3.7 very soon, likely tomorrow, based on the last version of branch 4.3. This should mark the end of official maintenance for branch 4.3, so if no major regression discovered in following few weeks, it will be the last release in 4.3 series. If there is something you know it needs to be pushed in branch 4.3, write back to mailing list.

Better place to change the FROM header for every INVITE
by Emanuele Gambaro 22 Jun '17

22 Jun '17

Hi I need to change the FROM header for every invite and replace the caller username with another data taken from mysql database. Which is the best place in kamailio routes to do a uac_replace_from ? It is correct to change the FROM header before the dialog creation, in “RELAY” route, just before the t_relay()? Thank you -- Emanuele Gambaro --- email: emanuele.gambaro(a)pynlab.com skype: sarbyn_work OpenPGP Key: https://goo.gl/fdeVnI

Help detecting t.38 and routing accordingly
by Tim Bowyer 22 Jun '17

22 Jun '17

Hi All, Trying to work out a way to detect and re-route inbound calls which negotiate or contain t.38 SDP to answer/process faxes efficiently. Plan is to put Kamailio in front of a quantity of FreeSwitch servers - most virtual, others physical. Virtual servers will handle inbound faxes which negotiate t.38, and physical servers will answer ulaw/alaw faxes with mod_spandsp. The bulk of inbound faxes negotiate t.38, but in order to scale our inbound system we need some way to work out which way to send the calls prior to the dispatcher. Many thanks for your help in advance, Tim

maybe found a bug in TM module - how to proceed?
by Valentin Christoph 21 Jun '17

Hi all, I am using kamailio 4.4.5 in an IMS setup as S-CSCF. I have got problems when trying to deliver an INVITE request to a distinct PSI at an AS. I receive the SIP response "555 AS Contacting Failed - iFC terminated dialog". I collected tshark traces and synchronously WITH_DEBUG kamailio logs. I think, I have found the root cause in the source code of the TM module and would like to issue an official bug report. How to proceed?

SIP-Trunk Kamailio and Asterisk
by Володимир Іванець 21 Jun '17

21 Jun '17

Hello everyone, I'm doing some custom Kamailio configuration to achieve few things but seem to be stuck with SIP trunks. I'm currently using Kamailio 4.4.5 and here is what I have at the moment: *1.* Asterisk 11.25.1 servers behing Kamailio using RealTime for SIP peers. *2.* Route that checks if packet was sent from one of configured SIP trunks. This part works correctly: *route[FROMPSTN] {* * xlog("== FROMPSTN ==\n");* * $var(socket) = $si + ":" + $sp;* * xlog("**** $var(socket)\n");* * xlog("**** $(sht(trunks_kamailio=>$var(socket)))\n");* * if ($(sht(trunks_kamailio=>$var(socket))) != $null) {* * xlog("**** From $(sht(trunks_kamailio=>$var(socket))) PSTN\n");* * return 1;* * }* * xlog("**** Not from PSTN\n");* * return -1;* *}* *3.* Here is a fragment that sends INVITE packet to *TOASTERISK* route if it was received from one of trunks. I have 4444444444(a)XXX.XXX.XXX.XXX hardcoded for now, and in my configuration 4444444444 and XXX.XXX.XXX.XXX represent my real caller id number and carrier's IP address: *if(route(FROMPSTN)) {* * uac_replace_from("sip:4444444444@XXX.XXX.XXX.XXX");* * route(TOASTERISK);* *}* *4.* TOASTERISK basically has folloving fragment that load balances traffic between Asterisk nodes: *if(!ds_select_dst("0", "4")) {* * xlog("**** Call was not sent to none of Asterisk hosts\n");* * if(!is_method("REGISTER")) {* * xlog("**** Method is not REGISTER\n");* * send_reply("404", "No destination");* * }* * xlog("**** Dispatcher fail\n");* * exit;* *}* So when I'm making a call to my test number, I can see following incomming packet in Asterisk from Kamailio. From header has correct caller id number and carrier's IP address (192.168.88.5 is Kamailio's internal IP address): [image: Вбудоване зображення 1] And when Asterisk tries to find a maching peer for this incoming call, it is using Kamailio's instead of Carrier's IP address. So it is actually finds one of peers (101-XXXXXXX) that is being authenticated on Kamailio as many others: [image: Вбудоване зображення 2] I'm not sure if Asterisk is just using packet's source IP to lookup for corresponding peer or something else from it's content. I will really appreciate any help on this. Thanks a lot!

Cannot login Siremis

Hey. Just installed Kamailio onto CentOS 6 using the available YUM repos., and Siremis (v4.4). I seem to be having the same issue as this was reported https://github.com/asipto/siremis/issues/3 I have retried the Siremis install again as suggested, and I still cannot login with the same results that person has: click login and nothing is occurring, except for the text appearing which states "Processing Login." There is no error in the httpd error_log file. Anything else to look for? Thanks!

app_lua and sqlops returns error
by Sebastian Damm 20 Jun '17

20 Jun '17

Hi, I'm developing some routing logic with Kamailio 5.0.1 and app_lua. I've integrated my lua script and now I'm trying to use sqlops within the script. I want to use the reconnect stuff of sqlops instead of implementing it by myself. This is what the Kamailio config looks like: [..] loadmodule "db_mysql.so" loadmodule "sqlops.so" loadmodule "app_lua.so" [..] modparam("sqlops", "sqlcon", "ca=>mysql://kamailio:foobar@127.0.0.1/kamailio") modparam("app_lua", "reload", 1) modparam("app_lua", "register", "sqlops") modparam("app_lua", "load", "/etc/kamailio/playground.lua") ####### Routing Logic ######## # Main SIP request routing logic request_route { route(everythinginlua); } onreply_route { route(everythinginlua); } route[everythinginlua] { if(!lua_run("handle_packet")) { xlog("L_ERR", "SCRIPT: failed to execute lua function!\n"); } drop; exit; } The lua script looks like this: -- Start of script function handle_packet() sr.log("L_INFO", "Got packet method "..sr.pv.get("$rm")) local status = sr.sqlops.sql_query("ca", "SELECT * FROM table", "fooresult") sr.err("sql query returned status "..status) end -- End of script Now when a packet comes in, I see the following in the log file: Jun 14 11:19:59 busch /usr/sbin/kamailio[13254]: ERROR: app_lua [app_lua_sr.c:104]: lua_sr_log(): Got packet method REGISTER Jun 14 11:19:59 busch /usr/sbin/kamailio[13254]: ERROR: app_lua [app_lua_api.c:713]: app_lua_run_ex(): error from Lua: /etc/kamailio/playground.lua:4: attempt to call field 'sql_query' (a nil value) Jun 14 11:19:59 busch /usr/sbin/kamailio[13254]: ERROR: app_lua [app_lua_api.c:726]: app_lua_run_ex(): error executing: handle_packet (err: 2) Jun 14 11:19:59 busch /usr/sbin/kamailio[13254]: ERROR: <script>: SCRIPT: failed to execute lua function! Looks to me as if the functions of sqlops don't get exported to my lua script. According to the documentation, after specifying the "register" modparam, I should be able to access those functions. What am I missing? Thanks in advance Sebastian

Re: [SR-Users] re.subst does not work with $var?
by Pranathi Venkatayogi 19 Jun '17

Any input please? How do I use these methods with $var... I get the same behavior when I use avp_subst as well. From: Pranathi Venkatayogi Sent: Thursday, June 15, 2017 6:22 PM To: Kamailio (SER) - Users Mailing List <sr-users(a)lists.kamailio.org> Subject: re.subst does not work with $var? I am trying to replace "domain1" with "domain2" in the msrp(body). Following stmt works where in I specify domain strings as literals. var(modBody) = $(msrp(body){re.subst,/()(domain1)()/domain2/g}); I am having trouble making the same work with $var variables. See below - this code does not do the replacement - $var(domain1) = "()(domain1)()"; $var(domain2) = "domain2"; var(modBody2) = $(msrp(body){re.subst,/$var(domain1)/$var(domain2)/g}); Any clue/ideas or is it by design?

two way routing
by Jean Cérien 19 Jun '17

19 Jun '17

Hello I am looking at the following configuration: 1/ voip providers, with different external sip servers, will send calls to kamailio, that will dispatch them to asterisk servers, with load balancing & failover. The IP of the asterisk servers are known and fixed. 2/ the asterisk servers will also place calls, going through kamailio, that will dispatch them to the voip provider sip servers, based on R-URI / Prefix. I've achieved #1 with dispatcher module, I've seen carrierroute module that can achieve #2, but I dont really grasp how to put the two together. I have the feeling that #1 can also be done with carrierroute, and that I only need to check if the 'from' domain is one my asterisk, and chose a different routing table, but I dont see how to do that is that a valid approch ? where should I look to do that ? thanks J.

How to change MSRP from sip address?
by Pranathi Venkatayogi 19 Jun '17

19 Jun '17

I need to replace the "From" address of MSRP message with something different. I noticed that module does not allow one to set values from config file. What does it take to enable this functionality? Does anyone have a prototype I can leverage? Need to replace from domain with some other domain - Given: MSRP body is - From: cust3 <sip:cust3@devtranslation.sms-test.cyracom.com>#015#012To: <sip:agent1@xmpp.xgw.cyracomdev.com>#015#012DateTime: ..... Wanted: MSRP body is - From: cust3 <sip:cust3@new domain >#015#012To: <sip:agent1@xmpp.xgw.cyracomdev.com>#015#012DateTime: .....

Planning Kamailio v4.4.6
by Daniel-Constantin Mierla 16 Jun '17

16 Jun '17

Hello, I backported a consistent set of patches to branch 4.4 and plan to release v4.4.6 in the next days. Should anyone be interested in that branch, it would be good to review and see if any relevant fix from newer branches is missing in order to assert the feasibility of backporting. If time allows, 4.4.6 can be out as soon as tomorrow afternoon, if not, sometime during following days. Cheers, Daniel -- Daniel-Constantin Mierla www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - www.asipto.com Kamailio World Conference - www.kamailioworld.com

re.subst does not work with $var?
by Pranathi Venkatayogi 15 Jun '17

15 Jun '17

I am trying to replace "domain1" with "domain2" in the msrp(body). Following stmt works where in I specify domain strings as literals. var(modBody) = $(msrp(body){re.subst,/()(domain1)()/domain2/g}); I am having trouble making the same work with $var variables. See below - this code does not do the replacement - $var(domain1) = "()(domain1)()"; $var(domain2) = "domain2"; var(modBody2) = $(msrp(body){re.subst,/$var(domain1)/$var(domain2)/g}); Any clue/ideas or is it by design?

SUBSCRIBE within
by Annus Fictus 14 Jun '17

14 Jun '17

Hello, I'm using Kamailio in a Multi Domain setting. I have a problem with SUBSCRIBE within a Dialog With the first subscribe no problem: SUBSCRIBE -> 407 Proxy Auth -> SUBSCRIBE -> 200 OK In the 200 OK the Contact header contain the Kamailio IP so when the Softphone send another SUBSCRIBE within the dialog (at the IP present on the contact header) Kamailio answer whit a 404 Not Here because I use these lines: if (is_method("SUBSCRIBE") && is_uri_host_local()) { # in-dialog subscribe requests route(PRESENCE); exit; } So, as the softphone send the new SUBSCRIBE to Kamailio IP and not the Kamailio domain, Kamailio not use this block but: sl_send_reply("404","Not here"); exit; } My question is: Why Kamailio in the Contact Header of 200 OK of SUBSCRIBE use the public IP and not the domain? Regards

user management of kamailio cluster
by zhaoguojie2010＠163.com 12 Jun '17

12 Jun '17

Hi all. I have 10 kamailio servers across the world. Each of them has a public ip which is also their SIP DOMAIN. When a user register on my service, I'd use their username and password to generate 10 sip accounts, one for each kamailio server so that they can register to any of them. So for each user I will have to insert 10 records in the subscriber table. Is there a better way to do this? Cheers Jesse

Hello, In now days i have a strange issue in registering users in kamailio. My senario is the following: I setup kamailio with basic configurations and i created 2000 users in mysql(from 10000 to12000). With registration senario with SIPP tool, i have not issue and every things works right,(Notice that we know SIPP uses the same source ip for all registration), But when i use Spirent Abacus 5000(Test solution for voice, VoLTE and IMS), the kamailio just register 1024 users and other users could not register to kamailio. Spirent Abacus 5000 use the different source ip for each registration. I have these error in syslog message: ERROR: sl [../../core/forward.h:201]: msg_send buffer(): udp_send failed one possible reason is the server is bound to localhost I set this parameter in kamailio configurations, but the issue dont solved: open_files_limits:2048 and in linux configuration: ulimit -n 999999 Please let me know how can i fixed it?
