destination ip address
by Péter Barabás 12 Jul '16

12 Jul '16

Hi All, i need to store some information in routing_logic script into database with useing SQLOPS module. I made a custom table and store such data like source and destination username, domain, ip address and port. It works fine for almost every parameter except destination IP address and port. I want to ask what is the correct way to determine the destination IP address and port of a user for a MESSAGE, INVITE or BYE message? The $Ri and $Rp is not the correct ones. Thanks.

getting the local 408 response
by Jayesh Nambiar 12 Jul '16

12 Jul '16

Hi, I'm looking to catch the local 408 response generated by kamailio after the fr_timer strikes in. I was assuming to get it in the sl:local-request, but I dont see it in my log messages. I can catch responses like a 200 for register or a 487 for a message who's transaction is not yet created. Any proper way on how do I get to know when kamailio generates a local 408? I'm on the master branch (commit: 54562b873c2c3d0a04f0587e7706188a3eb19a74). Thanks, - Jayesh

Calculating time differences
by Sebastian Damm 11 Jul '16

11 Jul '16

Hi, we are suspending a transaction at one place in our route and resume it later. I want to log the time difference between suspending and resuming. I thought I could do it with saving $TV(Sn), but apparently I can't. Kamailio says, it can't convert the saved value into integer. This true, of course. I was searching for a transformation function converting this string into float, but there is none. Is there any way to calculate a time difference other than to live with seconds-only precision? Best Regards, Sebastian

Kamailio WEBRTC questions/ confusions
by Zaka 10 Jul '16

10 Jul '16

Dear List: I wonder if this has been asked before. Please ignore or point to the appropriate source, if needed. Simply, I have little experience with SIP servlets implementing WEBRTC/ Click2Call etc... Considering a Call Centre scenario offering a WEBRTC solution. Following are the confusions regarding requirements: 1: A Kamailio Box (running WEBSOCKET.config) 2: Customer will use web browser (websocket compatible of course) and enter address of the KAMAILIO Box or we shall need another KAMAILIO to statelessly forward the call to next available operator using Hunt Group or similar scheme? 3: If we don't plan to implement TLS/ MSRP (disabling these in the config file should be suffice?) 4: Last, but not the least, how will the users send request for login from browser? (assuming they have accounts created in the DB on Kamailio Box running WEBSOCKET supported KAMAILIO) With anticipatory thanks & regards, Zaka

re-INVITE on IP Change with Outbound
by Colin Morelli 08 Jul '16

08 Jul '16

Hey list, So I'm using the outbound module to ensure subsequent requests are delivered over an active TCP connection established by the mobile client. However, now I'm trying to add support for automatically responding to network changes (WiFi <-> LTE), and it's creating problems. Primarily, the issue is that when the device sends a re-INVITE for the call, its Route: header includes a flow-token corresponding to its *old* socket connection. Because the new request doesn't have the same source IP/port as the old connection did Kamailio thinks that the next route hop it needs to take is to pass the request over to the connection identified by the flow token. So it actually tries to re-open a TCP connection back out to the client even though I'm making the re-invite because that old transport is no longer valid. Does anyone have a recommended way of handling this case? I can add another header/param to the route header and manually remove it. Before loose_routing. Essentially, on in-dialog INVITE requests I want to ignore the outbound token on the originating side but I can't seem to find a way to do that without re-writing the header before loose_routing. Best, Colin

shtinc throws readonly error
by Sebastian Damm 08 Jul '16

Hi, I'm trying to use this line in one route: $shtinc(pushedUsers=>$avp(s:authuser)); However, when checking the syntax of this file, Kamailio says: 0(609) : <core> [cfg.y:3365]: yyerror_at(): parse error in config file /etc/kamailio/kamailio_sip_proxy.cfg, line 3304, column 2-39: read only pvar in assignment left side According to the pseudo vars documentation, I should be able to use it like that.

tsilo ts_append problem
by gmele 08 Jul '16

08 Jul '16

Hello, we are using tsilo to achieve mobile push notification in kamailio. In tsilo module documentation, ts_append() function is used with the pseudo variable “$tU” holding the username of the to-uri. Our config looks like : route[PUSHJOIN] { $var(hjoin) = 0; lock("$tu"); $var(hjoin) = $sht(vtp=>join::$tu); $var(hstored) = $sht(vtp=>stored::$tu); $sht(vtp=>join::$tu) = $null; unlock("$tu"); if ($var(hjoin)==0) { if ($var(hstored)) { ts_append("location", "$tU"); } return; } $var(id_index) = $(var(hjoin){s.select,0,:}{s.int}); $var(id_label) = $(var(hjoin){s.select,1,:}{s.int}); t_continue("$var(id_index)", "$var(id_label)", "INVRESUME"); } In ts_append() function code, ts_check_uri() is called on a variable holding a username and not a URI causing the failure of the function ts_check_uri() and resulting in ts_append() to exit. The following line is displayed in the log: [tsilo.c:205]: ts_check_uri(): bad uri [giovanni.mele]. The function ts_store() stores in the R-URI field the username and not the request URI. route[RELAY] { # enable additional event routes for forwarded requests # - serial forking, RTP relaying handling, a.s.o. if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) { if(!t_is_set("branch_route")) t_on_branch("MANAGE_BRANCH"); } if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } if (is_method("INVITE")) { if(!t_is_set("failure_route")) t_on_failure("MANAGE_FAILURE"); } if (!t_relay(PROXY_IP, PROXY_PORT)) { sl_reply_error(); } if (is_method("INVITE")) { ts_store(); $sht(vtp=>stored::$tu) = 1; route(SENDPUSH); } exit; } route[INVRESUME] { statsd_gauge("SIPRegistrar.InviteResumed", "+1"); lookup("location"); t_relay(PROXY_IP, PROXY_PORT); ts_store(); $sht(vtp=>stored::$tu) = 1; } With the command “kamcmd ts.dump” we can see the following lines: R-URIs: { R-URI: giovanni.mele Hash: 74014921 Transactions: { Transaction: { Tindex: 63704 Tlabel: 2105932514 } } } If we try to use the ts_append() function with the pseudo variable “$tu” holding the full to-uri address, there is no error returned by ts_check_uri() (as this is called on a correct URI) but the transaction corresponding to the to-uri cannot be found (maybe because the R-URI stored by ts_store() is the username and not the full R-URI). How can we make things work ? By storing the full R-URI with ts_store() ?

4.4.1: Only first UDP Listener is producing log messages
by Sebastian Damm 08 Jul '16

08 Jul '16

Hi, I upgraded one of our systems today to 4.4.1. And when checking whether everything is okay, I noticed, that only the first UDP listener (from kamcmd core.ps) is actually sending lines to the log. The only other logs I see are from usrloc timer worker. kamcmd> core.ps 10737 main process - attendant 10740 udp receiver child=0 sock=172.20.40.5:5060 10741 udp receiver child=1 sock=172.20.40.5:5060 10742 udp receiver child=2 sock=172.20.40.5:5060 10743 udp receiver child=3 sock=172.20.40.5:5060 We are sending quite a lot of information via xlog("L_NOTICE", "foo"); to syslog, but the only lines I see are from PID 10740. Kamailio works fine otherwise, handling all requests, the usrloc entries didn't drop, and customers don't complain. So I think it's only a logging issue. There are about 50k registrations on the machine and more than 10 Mbit of traffic. When I downgrade to 4.3.5, I get output from all listeners again. Has there been any change between 4.3 and 4.4 regarding logging? The upgrade document says nothing about this. Best Regards, Sebastian

A parameter with a life span of the entire dialog
by Jay Li 07 Jul '16

07 Jul '16

Dear All, I'm trying to set a few parameters for an "INVITE", and access their values in the failure routine if the call fails. $var() doesn't seem suitable for my purpose as it only lasts for one process. I think if I set a $var() in "INVITE", it will be gone when I receive the failure response. $sht() seems able to last long but it will be accessed by all processes which might include ones not belonging to the same dialog. I wonder if somebody would give me some suggestions here to handle such situations. Does Kamailio provide a mechanism to set up a parameter with a life span of the entire dialog? Thanks. Regards,Jay

t_check_trans() exits route execution if transaction is found
by Sebastian Damm 07 Jul '16

07 Jul '16

Hi, on one of our systems we are checking a few times whether a transaction already exists. We noticed that route execution stops if the transaction is found. And after looking into the code, we found that it seems to be intended like this. >From tm.c: int t_check_trans(struct sip_msg* msg) { if (msg->first_line.type==SIP_REPLY) { [..] } else { switch(t_check_msg(msg, 0)){ [..] case 1: /* found */ [..] return 0; /* exit from the script */ } } } Can anybody explain, why script execution should stop when a running transaction is found? I would expect that then the function returns 1 so I can use it in my if statement and continue with my routing script. Thanks already for an explanation, Sebastian

Are there any instructions on the exact configuration changes that need to be made to support Mongodb? For example, kamctl points to MySQL, etc Thanks! Chuks.

Locally originated BYE dialog database handle
by Dirk Teurlings - Signet B.V. 06 Jul '16

06 Jul '16

Hi, There's something going on with a locally originated BYE and the dialog module running with a database backend. Here's the scenario. Call gets setup, and is being monitored by outside processes (non-Kamailio). After a while these processes determine the call is taking too long (or too expensive), so it has to be killed. To do this we're using the kamcmd dlg.end_dlg with h_entry and h_id as parameter. This works to end the call, but is throws some weird issues into the routing. First off, the event_route[dialog:end] is not thrown 99% of the time, though I would expect it to. Second, This error pops up in the log /usr/sbin/kamailio[25094]: ERROR: dialog [dlg_db_handler.c:199]: use_dialog_table(): invalid database handle As if the command issued by kamcmd isn't able to get connected to the dialog database. In any case, this error results in the dialog entry for this call not being removed from the database. So this piles up after a while. Anybody any thoughts on this? Cheers, Dirk

(no subject)
by John Petrini 06 Jul '16

06 Jul '16

Hello, I'm trying to append a branch, assign it a q value so it has priority and serialize the new branch and the main branch. The goal is to send the new branch off to our CNAM provider, capture the CNAM in their reply to an $avp then drop the branch, stick the cnam in the main branch and allow the call to continue as normal. We do this currently using OpenSIPS with serialize_branches(1) but the of load_contacts() behavior seems to be different than serialize_branches. route[CNAM_DIPS] t_on_branch("CNAM_DIPS"); t_on_reply("CNAM_DIPS"); t_on_failure("CNAM_DIPS"); t_load_contacts(); t_next_contacts(); append_branch("sip:2223334444@22.33.444.55:5600;trans-type=5", "0.5"); relay(); break; Two problems. First when t_next_contacts is called I get the following error: ERROR: pv [pv_branch.c:58]: pv_get_branchx(): error accessing branch [0] So it looks like the branches aren't actually being loaded? Second problem is that despite the first error my call goes out on the branch I appended and I get a reply from the CNAM provider but Kamailio forwards that reply back to the phone causing the phone to send a second invite. In OpenSIPs we just called drop, to drop the branch and let the main branch continue but this doesn't seem to work in Kamailio. I've read and reread the documentaion but it doesn't seem to behave the way the documentation says it should. Is there something I'm missing? Is there a better way to accomplish this in Kamailio? Thank You, ___ John Petrini

Issue with userblacklist module after 4.4.2 upgrade
by Tim Balmer 06 Jul '16

06 Jul '16

Hello, We are running Kamailio version 4.4 and have our sipproxy servers configured to do auto updates within te same major version based on a 4 weekly schedule (we have 4 sipproxy / Kamailio servers). So this morning as expected the first of our sipproxy servers automatically upgraded from 4.4.1 to 4.4.2, unfortunately after this update we have issues with the userblacklist module. The problem is that with the 4.4.2 release every number is now matching our userblacklists although it is not really blacklisted. After some digging in the logs I found this is probably because the userblacklist module is looking for the wrong database table. With every check_user_blacklist call I see errors like this appearing in the logs: Jul 5 13:24:03 tel-dev-01 [err] /usr/sbin/kamailio[2834]: ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error on query: Table 'kamailio.<number>' doesn't exist (1146) Jul 5 13:24:03 tel-dev-01 [err] /usr/sbin/kamailio[2834]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query Jul 5 13:24:03 tel-dev-01 [err] /usr/sbin/kamailio[2834]: ERROR: userblacklist [db.c:68]: db_build_userbl_tree(): error while executing query. Jul 5 13:24:03 tel-dev-01 [err] /usr/sbin/kamailio[2834]: ERROR: userblacklist [userblacklist.c:277]: check_user_list(): cannot build d-tree I replaced the real number with <number> in the log output but it seems like the userblacklist module is now looking for a database table with the name of the number to check against. On our development server I tested setting the global userblacklist_table parameter and also passing the table parameter within the check_user_blacklist call but both are not making any difference. After downgrading the sipproxy back to 4.4.1 everything is working as expected again so it looks to me like a bug in the 4.4.2 release. Is anyone else experiencing the same issues after the 4.4.2 upgrade or is it just me doing something wrong? Best Regards, Tim Balmer

Kamailio summer-of-documentation - join the effort
by Olle E. Johansson 06 Jul '16

06 Jul '16

Hi! Looking for a summer-of-documentation project? Which README is the best? Which one is so full of Swedish that you totally fail to parse it? Check our documentation pages, suggest improvements on the mailing lists (or here on Facebook) and give us feedback! This is something you can spend your lazy summer days on - a nice cool drink, cool sunshades and Kamailio documentation! We constantly work to update our README files for every module and the cookbooks for the Kamailio core, the transformations and pseudovariables. But we’re developers, not casual administrators and propably fail to see some obvious things missing. Please tell us (feel free to use the mailing lists). And if you can - but not required at all - you can suggest rewrites in the XML source and upload to github. Let’s keep our docs up to date and make sure they really assist our users! http://kamailio.org/docs/modules/devel/ Have a great summer! Regards, /O

Kamailio blocked when using with Radius accounting when connection is lost with the database.
by Mx R 06 Jul '16

06 Jul '16

Hi there. I have the following scheme. 1. SIP server is running kamailio with module "acc", radiusclient-ng and freeradius. 2. DB server with MSSQL. The problem is the following, if the connection is lost with the database, no one can make calls. Even after the connection to the database is restored. We have to restart the radius and kamailio. And only after that can make calls. Kamailio logs rc_send_server: no reply from RADIUS server localhost: 1813 ERROR: acc [acc.c: 720]: acc_rad_request (): radius-ing failed Radius logs. Error: rlm_sql_unixodbc: SQL down 08S01 [unixODBC] [FreeTDS] [SQL Server] Write to the server failed Below are links to a similar problem. http://lists.opensips.org/pipermail/users/2012-March/021100.html http://lists.opensips.org/pipermail/users/2012-March/021102.html http://lists.opensips.org/pipermail/users/2012-March/021105.html http://lists.opensips.org/pipermail/users/2012-March/021128.html

Simple Kamailio configuration for Asterisk load balancing?
by Tickling Contest 06 Jul '16

06 Jul '16

Hello, I am beginning to front my Asterisk cluster with Kamailio and so far my biggest issue is the complete lack of quick-start-like documentation for this. Is there any place I can get a very simple HA configuration (telling me where the config files are, for starters, is a good thing) for Kamailio with the following features: (a) Support an arbitrarily large number of Asterisk servers (say, upto 10). (b) Offload SIP registration to a realtime/mysql DB used by the PBXs. Please also let me know if I should have to change my Asterisk PBX config in any way for this to happen. On a very related note, while I appreciate the fact that you need to _really_ understand SIP to configure Kamailio, it should be possible to get this setup by just running a script or GUI. It is difficult to find information on how to load balance multiple PBXs behind Kamailio. Thanks!

[rtprpoxy LB]
by Noriyuki Hayashi 06 Jul '16

06 Jul '16

Hi, Thank you for be used great KAMAILIO. Regarding rtpproxy LB. I configured as below. modparam("rtpproxy", "rtpproxy_sock", "udp:192.168.1.136:7722") modparam("rtpproxy", "rtpproxy_sock", "udp:192.168.1.137:7722") modparam("rtpproxy", "rtpproxy_sock", "udp:192.168.1.138:7722") modparam("rtpproxy", "rtpproxy_disable_tout", 20) modparam("rtpproxy", "rtpproxy_tout", 2) modparam("rtpproxy", "rtpproxy_retr", 2) I could not restart kamailio when one rtpproxy server is down. Does anyone tell this solution by the parameter or somthing ? I am looking forward from anyone. Thank you so much. Noriyuki Hayashi

I use a seperate machine for voicemail but I see no problem with other uses (I used to use it for playback of messages and transcoding ebtween incompatible endpoints). By using the prefixes in kamailio to the username in $ru I have in the extensions.conf: exten => _tovm-.,1,NoOp(leave voicemail) exten => _tovm-.,n,Answer() exten => _tovm-.,n,Set(CHANNEL(language)=nl) exten => _tovm-.,n,Voicemail(${EXTEN:5},us) exten => _tovm-.,n,Playback(Goodbye) exten => _tovm-.,n,Hangup() exten => _getvm-.,1,NoOp(read voicemail) exten => _getvm-.,n,Set(CHANNEL(language)=nl) exten => _getvm-.,n,VoicemailMain(${EXTEN:6}) exten => _getvm-.,n,Hangup() > The other question is that i actually though that you need asterisk to > have users configured in sipusers realtime table to associate their > mailboxes, which i dont have since those users are stored in the > subscriber table of kamailio.

So yes I have a realtime sip users list (with host=dynamic,type=friend,insecure=port,invite, name/mailbox the kamailio username, no password (this machine is not directly accessible from outside)) You might not be able to have endpoints able to subscribe to notifications due to this.

dispatcher module not fetching attrs col from DB
by Jayesh Nambiar 05 Jul '16

05 Jul '16

Hi, I'm trying to use the dispatcher module with algo 9 for weighted distribution. I have a column attrs in the dispatcher table with value in the format "weight=90" for my destination addresses. But somehow the ds_list command always shows attrs as blank. I checked that kamailio doesn't fetch the attrs column at all; neither while starting up nor while calling ds_reload. This is the query that kamailio sends to my DB while starting up or calling the fifo ds_reload: select `setid`,`destination`,`flags`,`priority` from `dispatcher` I dont even see an attr column modparam in the documentation although kamailio didnt throw an error when I defined attr_col modparam for dispatcher module. Is there a different way to tell kamailio to fetch the attrs from the DB?? I'm using the 4.4.1 version. Thanks for any suggestion or pointers to solve this. - Jayesh

Kamailio v4.2.8 Released
by Daniel-Constantin Mierla 05 Jul '16

05 Jul '16

Hello, Kamailio SIP Server v4.2.8 stable release is out. This is a maintenance release of the previous stable branch, 4.2, that includes fixes since release of v4.2.7. There is no change to database schema or configuration language structure that you have to do on installations of v4.2.x. Deployments running previous v4.x.x versions are strongly recommended to be upgraded to v4.2.8 (or to 4.3.x/4.4.x series). Important: this version marks the end of planned releases from branch 4.2. From now on the focus is on maintaining the branches 4.4 and 4.3 for stable releases. For more details about version 4.2.8 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2016/07/kamailio-v4-2-8-released/ RPM, Debian/Ubuntu packages will be available soon as well. Note: the latest stable branch is 4.4, at this moment with its latest release v4.4.2. See more details about it at: * http://www.kamailio.org/w/kamailio-v4-4-0-release-notes/ Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/miconda - http://www.linkedin.com/in/miconda

[SR-USERS] Kamailio issues with Asterisk Voicemail
by TEG AMJG 05 Jul '16

05 Jul '16

Dear list: I am quite new to Kamailio and i am really struggling to get some answer to some questions i have been trying to get answers by reading documentation and other questions or solutions around internet. Even though i am integrating Kamailio with two Asterisk boxes with the module dispatcher, i didnt follow the quite popular guide of Asterisk Kamailio Realtime Integration ( http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb). The reason why i didnt is that it actually behaved weird since i wanted Kamailio to be a stateful proxy and also wanted Kamailio to act as a Registrar Server and Location Server using subscriber and location tables of kamailio database, keeping both Asterisk strictly as Media Servers. Also i have been able to solve some NAT Traversal issues using RTPProxy and not using those Asterisk boxes with their nat or qualify parameters to solve NAT issues. Most of my solution started following this guide ( http://saevolgo.blogspot.com/2013/08/rtpproxy-revisited-kamailio-40.html) which let me handle registration and location with Kamailio and also changed it putting kamailio behind NAT. Now to the real question, is there anyway to include Asterisk voicemail functionality with the solution I already mentioned? the question is because, as I far as I know, Asterisk needs to associate mailboxes to its users. So i believe that i have to practically change most of my solution and find a way to make Kamailio register and locate users with the Realtime integration of Asterisk and map the registration accordingly to the table fields. But it destroys most of my NAT and register solution since i also configured one of the private IPs as a peer in Asterisk sort of like in that guide [Kamailio] type=friend host=192.168.1.244 port=5060 disallow=all allow=gsm allow=g729 allow=alaw allow=ulaw Sorry for making the question so long and to be quite ignorant with some of the concepts involving Kamailio with Asterisk Thanks Alejandro

Increase diversion counter
by Igor Potjevlesch 05 Jul '16

Hello, I'm looking for the best way to increase the Diversion counter. If my Kamailio is the first to generate a call forward I can manage this with static value into suffix params. But, if the Diversion counter is already set, I don't see how to handle this properly. Someone has already work on this? Regards, Igor.

Kamailio and Mongodb
by C. 04 Jul '16

04 Jul '16

Hi, I have followed instructions on setting up Kamailio with MongoDB backend, and successfully compiled and installed kamailio with the db_mongo module. It can start successfully. However, when I tried to add users using the command: kamctl add test testpasswd test(a)mysipserver.com <mailto:test@mysipserver.com> It fails because it is trying to default to MYSQL. Here is the result of that command: WARNING: database engine not found - tried 'MYSQL' ERROR: This command requires a database engine - none was loaded When I take a look at the kamctl script, it lists all the other kinds of database engines, except MongoDb, so this is probably why it is failing. How can I use kamctl to create the required Mongodb collections (like users, subscribers, etc) that Kamaiio will then use?My kamailio.cfg seem to be working ok, as I seem to be able to connect to the database (I modified the file to use db_mongo module), and I create the initial collections as listed here - https://www.kamailio.org/wiki/tutorials/kamailio-and-mongodb <https://www.kamailio.org/wiki/tutorials/kamailio-and-mongodb> Thanks, Chuks.

Regarding config-engines
by Alexander Rudenko 04 Jul '16

04 Jul '16

Hi, Question about future config-engines. Will it be possible to use connectors/drivers via the engine script and is it a good Idea? E.g. I have specific database and python driver for that database. May I use simple 'import dbdriver', create connection to the db, use it inside python engine script, etc? In general, in case there is no kamailio connector module for scpecific database, I would use python connector. Thanks in advance! -- *Alexander Rudenko*

re-Invite in the failure route
by Jay Li 04 Jul '16

04 Jul '16

Dear All, Hopefully I'll be able to get some help here on re-INVITE in the failure route. For example I have a couple of PSTN gateway options. I'd like to try them by priorities. In case the one with top priority couldn't go through(e.g. returned 5XX on INVITE), I'd like to re-INVITE through another provider in the failure route. Not sure what I should do for such cases. Thanks. Regards,Jay

Distributed Authentication
by Colin Morelli 01 Jul '16

01 Jul '16

Hey all, I'm running a cluster of Kamailio instances as a proxy/registrar for another cluster of Freeswitch instances. I'm using http_async_client to make HTTP queries to my API to fetch credentials on auth challenges. Kamailio performs generating the header, and validating the result based on the data provided from my API. I'm fairly sure the answer is no, but I was wondering if Kamailio has any mechanism for getting access to the nonce/nc values in the challenges and responses so I can store them somewhere accessible to the whole cluster. Because my instances are transaction stateful, the request that is challenged and the subsequent request with the response may be routed to different instances and I want to validate the nonce correctly. I can move all of this into the API (the digest auth and verification), but my next question would be whether or not there are any APIs for getting access to this information in a structured format, or if I should just shove the whole digest auth header in the request to my API and parse/verify there. Thanks in advance. Best, Colin

Serialize Branches Based on q value
by John Petrini 01 Jul '16

01 Jul '16

Hello, I'm trying to append a branch, assign it a q value so it has priority and serialize the new branch and the main branch. The goal is to send the new branch off to our CNAM provider, capture the CNAM in their reply to a $var then drop the branch, stick the cnam in the main branch and allow the call to continue as normal. We do this currently using OpenSIPS and the serialize_branches(1) but the of load_contacts() seems to be different than serialize_branches. route[CNAM_DIPS] t_on_branch("CNAM_DIPS"); t_on_reply("CNAM_DIPS"); t_on_failure("CNAM_DIPS"); t_load_contacts(); t_next_contacts(); append_branch("sip:2223334444@22.33.444.55:5600;trans-type=5", "0.5"); relay(); break; Two problems. First when t_next_contacts is called I get the following error: ERROR: pv [pv_branch.c:58]: pv_get_branchx(): error accessing branch [0] Second problem is that my call goes out on the branch I appended and I get a reply from the CNAM provider but Kamailio forwards that reply back to the phone causing the phone to send a second invite. In OpenSIPs we just called drop, to drop the branch and let the main branch continue but this doesn't seem to work in Kamailio. I've read and reread the documentaion but it doesn't seem to behave the way the documentation says it should. Is there something I'm missing? Is there a better way to accomplish this in Kamailio? Thank You, ___ John Petrini

Dialplan module doubt
by José Seabra 01 Jul '16

01 Jul '16

Hello there, I'm evaluating if I can use dial-plan and dispatcher module to build a kamailio routing server to route calls based on number dialed(sometimes the number dialed can be Alphanumeric). I'm expecting have lot of dial-plan entries, some of them with manipulations, others without. Anyone can see here any limitation on this implementation? One thing that I have noticed is that dial-plan module enforces me to fill the fields substr_exp and repl_exp even if i don't have any manipulations to apply. I'm also concerning about performance issues with lot of dialplan entries. What are your thoughts about this solution? Thank you -- José Seabra

ACK / BYE transaction problem
by Oliver Roth 01 Jul '16

01 Jul '16

Hi all Follow scenario Class5 system [c5] --> Loadbalancer kamailio (dispatcher module) [lbl] ---> gateway kamailio [gw] --> carrier [carr] I get Invites from [c5] with Request ,To, from, contact, pid in national format 0794445566 [lbl] dispatches this to [gw] For the [carr] I need international format. So doing these transactions in [gw] And sending to [carr] in international format Request, to, from, contact, ... => 417794445566 Everything ok Then I get a 100, 183 and even 200 from [carr] Ack is coming from [c5] to [lbl] and [gw] - but then it stocks The ACK is not sent to the [carr] I kamailio log I see DEBUG: RFC3261 transaction matching failed DEBUG: t_lookup_request: no transaction found So for me, the ACK cannot be assigned to a transaction and gets discarded by if ( is_method("ACK") ) { xlog(,"L_INFO", "WITHINDLG ACK - not loose route\n"); if ( t_check_trans() ) { xlog(,"L_INFO", "WITHINDLG ACK - t_check_trans() \n"); # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { xlog(,"L_INFO", "WITHINDLG ACK - not t_check_trans() DISCARD!!\n"); # ACK without matching transaction ... ignore and discard route(NATMANAGE); #t_relay(); #exit; Any idea? Problem with modifying the sip tags? Or problem with the dialog? Thanks for helping OIi

Kamailio Iterate All Headers
by Colin Morelli 01 Jul '16

01 Jul '16

Hey all, Back with more questions. I'm using Kamailio to make an HTTP call to my API to perform authentication and message routing. Currently, I'm trying to build up the post body that I send to my API to make those decisions. I've cherry picked a few of the headers that are important in my routing decisions. But, ideally, I'd like to just iterate over all the SIP message headers and append them as request parameters to my API call. Is this possible with Kamailio? I've been looking through the docs and can't seem to find a function to iterate the full list of headers. Thanks in advance. Best, Colin

Kamailio Load Balancer Architecture
by Daryn Johnson 30 Jun '16

30 Jun '16

I am interested in opinions and suggestions about load balancing with Kamailio. I work for an ITSP that currently uses Oracle & Broadsoft, and I am working to design and develop an open source solution using Kamailio (Proxy, Registrar, LB) & other Application/Media servers for more flexibility and freedom :) Thank you ALL for the work you have put in on Kamailio! After much reading and configuration I have a Kamailio 'proxy' setup, with endpoints registered using the Registrar module, and calls being sent/received to/from the PSTN. I am interested in separating the Load Balancers from the Registrars & logic, for security and in order to be able to scale appropriately. I will be using the dispatcher module for both load balancers and proxies using the following architecture: PublicIP = 5.5.5.5; Private IP = 192.168.1.0/24 USERS (Public Internet) ==> (public: 5.5.5.5) [ Kamailio (LoadBalancer, Firewall, Sanity Checks) ] (core:192.168.1.2) ==> [ Kamailio Registrar, Proxy, PSTN GW ] ==> AppServers or PSTN GW (we can access our PSTN gateways Via our Core using Private IPs) Questions: 1) Is it overkill to separate the LB & Proxy/Registrars? 2) Is this a common architecture & anyone configured this architecture successfully? Thanks in advance for your help! *Daryn Johnson* *Senior VoIP Engineer*

rtpengine allow_op problem
by david 29 Jun '16

29 Jun '16

hello all i have been taking a look to the rtpengine.c code and i found that the issue has relation with the queried_nodes_limit which had 50 defalut value, so before it was reached in the loop, we received a request/response retransmision doing all the same. anycase, the issue it's because when allow_op is applied, the select_rtpp_node gets a node even having the node disabled by the first attemp (having the rtpengine node down), and it does the loop. if it's not applied, we dont get a node at the retry. but adjusting the number of queried_nodes_limit to a value to be reached before a request retransmission arrives, i guess it should be enough (¿?) best regards david escartin

Hi, Found a error in the documentation of the DMQ module (http://kamailio.org/docs/modules/devel/modules/dmq.html#dmq.p.num_workers). In the documentation there is a example: modparam("dmq", "num_threads", 4) If i'm correct this should be: modparam("dmq", "num_workers", 4) Thanks, Jan

Kamailio - PSTN (kamailio) - rtpproxy issue
by Filippo Graziola 28 Jun '16

28 Jun '16

Hello everybody, I have a local kamailio+rtpproxy under NAT listening on multiple local interfaces (vlans) which works fluenty for all local user indipendently and engages rtpproxy correctly. I have another working kamailio+rtpproxy which is accessible from everywhere at a public address and I would like to route to it some specific calls from the local server. So, in the local kamailio configuration file I defined WITH_PSTN (all the necessary option) and INVITE/OK/BYE messages are going correctly to the destination. The problem is that I have no audio on both ways. After some packet sniffing, I tried killing local rtpproxy process and now calls to PSTN have also audio both ways. >From these tests, if my configuration is correct, when routing the call to PSTN gateway I should disable the local rtpproxy, and I'm in doubt about how I can do this. Could you help me? Should I change NAT flags in the PSTN route? Thanks

Hello, i've installled the new version of kamailio 4.4.1 . in 2 different server , with acc module and these parameters: modparam("acc", "time_mode", 2) modparam("acc", "time_attr", "seconds") should be seconds.millisec On the first server in acc table , in field seconds i have values like this 1466493457.85, this is correct timestamp ( this server have centos 86_64) In the other server , i have values like 1913113.702 , that is wrong timestamp .

Planning release of v4.4.2 and other v4.x.y
by Daniel-Constantin Mierla 28 Jun '16

28 Jun '16

Hello, I am considering to release kamailio v4.4.2 next week along with the corresponding patch releases for branches 4.3 and 4.2. It will likely be the last release in series 4.2 to mark its end of official packaging. I would also consider a new patch release in 4.1.x, if that is still used by many out there to get packages that fix the libssl version matching -- Victor should say if the packages for this branch can still be generated in order to make sense doing this release. Anyhow, report any issues you are aware and are not yet announced for branches 4.4 and 4.3 to the bug tracker as soon as possible to get a chance to be fixed by release date. Likely 4.4.2 will be next Tuesday, June 29, with the other branches done in the following days. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com - http://www.kamailio.org http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

userblacklist use avp for check_blacklist
by Jan Hazenberg 28 Jun '16

28 Jun '16

Hello, I'm trying to use the userblacklist module to implement a global blacklist. I have a few questions about the module. Is it possible to use a avp for the check_blacklist function? If i'm correct it will only parse the request URI, but i'm rewriting the URI in a branch route to allow different formats to different destinations. Or is this only possible with the check_user_blacklist function? I also have a issue with numbers in E164 format with a leading +. I tried to escape this with a \ in the database but it will not load the entry's when i use the + in front of the number. Is the + supported by this module or should i strip it before the function and add it again afterwards? Thanks, Jan

behaviour of uac_redirect module
by Dirk Teurlings - Signet B.V. 27 Jun '16

27 Jun '16

Hi, Testing with latest stable 4.4 Kamailio at the moment, and running into the following issue. I have a setup that sends a 302 to do a Moved Temporarily to another extension. To update the Contact header accordingly, I use the get_redirects function in the failure_route. get_redirects('*', 'Redirects') This results in the following packet U 192.168.10.246:5060 -> 192.168.10.245:5060 SIP/2.0 302 Moved Temporarily. Via: SIP/2.0/UDP 192.168.10.245:5060;branch=z9hG4bK40b58e09;rport=5060;received=192.168.10.245. From: "+31........" <sip:+31........@192.168.10.245>;tag=as42745abe. To: <sip:+31........@192.168.10.246>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-f67d. Call-ID: 576349c40a7cb77a06230e181831672d@192.168.10.245:5060. CSeq: 102 INVITE. Contact: <sip:06........@sip.example.net>, <sip:06........@sip.example.net>;q=0.01. Server: sip.example.net. Content-Length: 0. . This works, but I don't want ACC to account for anything, so I tried: get_redirects('*') But this results in the following packet U 192.168.10.246:5060 -> 192.168.10.245:5060 SIP/2.0 302 Moved Temporarily. Via: SIP/2.0/UDP 192.168.10.245:5060;branch=z9hG4bK185f4fdd;rport=5060;received=192.168.10.245. From: "+31........" <sip:+31........@192.168.10.245>;tag=as13f23689. To: <sip:+31........@192.168.10.246>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-b5fe. Call-ID: 336a16912db412d418f7f7495e2574f5@192.168.10.245:5060. CSeq: 102 INVITE. Contact: <sip:accountname@sip.example.net>, <sip:06........@sip.example.net>;q=0.01, <sip:06........@sip.example.net>;q=0.01. Server: sip.example.net. Content-Length: 0. . Notice the extra accountname Contact, this results in a forward that doesn't work for the mediaserver. To me the documentation about the function states that there should be no difference between using it with or without accounting as far as SIP messages go. Is this a bug, or is this by design? Cheers, Dirk

Get full body from http POST request
by Joel Serrano | VOZELIA 26 Jun '16

26 Jun '16

Hi, I'm using http_query (POST method) to interact with an API. This API responds with a JSON. Is there a way to get the full body and after parse that JSON? Example response: { "error": { "code": 404, "message": "Destination not Found" } } Currently, I'm only being able to get the first line, in the previous example it would be: "{" According to the doc, that is the expected behavior: If HTTP server returns a class 2xx, 3xx or 4xx reply, the first line of the reply's body (if any) is stored in “result” parameter, which must be a writable pseudo variable. I don't have the ability to get the response in 1 single line like: { "error": { "code": 404, "message": "Destination not Found" } } How can I get the full body instead of only the first line? Thanks. Best regards, Joel.

Hi, If you receive an INVITE with 2 diversion headers such as (in this order): Diversion: <sip:9975@X.X.X.X:5060>;privacy=off;screen=no; reason=user-busy; counter=1 Diversion: <sip:1234567890@Z.Z.Z.Z:5060>;privacy=off;screen=no; reason=unknown; counter=1 How is a nice way of extracting the user part from the URI of the last one? (in this case: 1234567890) Problems I have found: $(di{uri.user}) ---> Give mes the user part of the URI of the first header, in this case: 9975 Is there a way to tell $di to get its value from the last header instead of the first one? This example works: $(hdr(Diversion)[-1]{param.name,0}{s.strip,1}{s.striptail,1}{uri.user}) But I think it is very hacky... Any better approach anyone can suggest me? Thanks in advance. Best regards, Joel.

Public vs Internal IPs
by Colin Morelli 25 Jun '16

25 Jun '16

Hey all, When using Kamailio at the edge - what's the best practice around how to advertise your Record-Route? I assume it's going to involve the use of a double-RR with both the public and private IPs. However, I'm running in AWS where the host doesn't have two interfaces with both a public and private IP. So, I set the host's public IP as the advertised address while Kamailio binds to the local IP. But now how do I get Kamailio to know that it needs to double-RR in this case? Thanks, Colin

Specify alternative OpenSSL engine for Kamailio
by Joel Serrano | VOZELIA 25 Jun '16

25 Jun '16

Hi, This is a similar question on a previous thread: "[SR-Users] Compiling kamailio with custom openssl" Is it possible to specify a different OpenSSL engine for kamailio to use? For example: On nginx you have the config param: ssl_engine <engine> On apache you have the config param: SSLCryptoDevice <engine> Is there anything similar on Kamailio? We are using debian 8 with openssl-1.0.1t and these are the available engines: root@debian:/usr/lib/x86_64-linux-gnu/openssl-1.0.0/engines# ls -l total 404 -rw-r--r-- 1 root root 19512 Jun 21 11:07 lib4758cca.so -rw-r--r-- 1 root root 19784 Jun 21 11:07 libaep.so -rw-r--r-- 1 root root 15576 Jun 21 11:07 libatalla.so -rw-r--r-- 1 root root 6104 Jun 21 11:07 libcapi.so -rw-r--r-- 1 root root 24232 Jun 21 11:07 libchil.so -rw-r--r-- 1 root root 19864 Jun 21 11:07 libcswift.so -rw-r--r-- 1 root root 6104 Jun 21 11:07 libgmp.so -rw-r--r-- 1 root root 93304 Jun 21 11:07 libgost.so -rw-r--r-- 1 root root 15432 Jun 21 11:07 libnuron.so -rw-r--r-- 1 root root 6104 Jun 21 11:07 libpadlock.so -rw-r--r-- 1 root root 24096 Jun 21 11:07 libsureware.so -rw-r--r-- 1 root root 19784 Jun 21 11:07 libubsec.so root@debian:/usr/lib/x86_64-linux-gnu/openssl-1.0.0/engines# The reason is we have another server with a Cavium SSL card, which provides a dynamic engine: -rw-r--r-- 1 root root 127968 Jun 23 15:18 libcavium.so If it is not possible via config parameter, is there a way to specify the openssl engine to use before compiling? Thanks in advance. Best regards, Joel.

Count number of headers of type
by Joel Serrano | VOZELIA 25 Jun '16

25 Jun '16

Hi, It there an easy way to count the number of existing headers of certain type? For example: - How many 'via' headers: $hdrcount(Via) ? - How many 'diversion' headers: $hdrcount(Diversion) ? The $hdrcount is an example, just wondering if there is an easy way to get the number. Thanks. Best regards, Joel.

t_on_failure route not being called
by Colin Morelli 24 Jun '16

24 Jun '16

Hey all, I'm using a combination of http_async_client and rtjson to query my API and retrieve a JSON target route set for an incoming SIP request that Kamailio will forward to. The HTTP portion of it works great. I'm able to hit my API and get back a JSON document. Additionally, the rtjson parsing appears to work, because the request is hitting my freeswitch instance. However, FS is responding with a 503 (I'm intentionally doing this for testing), and Kamailio isn't calling my t_on_failure route. I've pasted the relevant portion of my config below - would be great if anyone has any insights. tl;dr: the "REROUTE" route section below isn't being reached even when FS responds with a 503. Best, Colin route[ROUTING_REPLY] { if $http_ok && $http_rs == 200 { xlog("L_INFO", "$ci|log|loaded target route set from document $http_rb\n"); rtjson_init_routes("$http_rb"); rtjson_push_routes(); xlog("L_INFO", "$ci|log|attempting to relay request towards $du\n"); t_on_failure("REROUTE"); t_set_fr(0, 1000); t_relay(); } else { send_reply("480", "Temporarily Unavailable"); } } route[REROUTE] { xlog("L_WARN", "$ci|log|relay to destination $du failed, checking next route\n"); if (rtjson_next_route()) { xlog("L_INFO", "$ci|log|additional route found, directing request to $du\n"); t_on_failure("REROUTE"); t_set_fr(0, 1000); t_relay(); } else { xlog("L_WARN", "$ci|log|route list exhausted, failing request\n"); send_reply("480", "Temporarily Unavailable"); exit; } }

How to understad that user is de-registrating
by Alexandru Covalschi 24 Jun '16

24 Jun '16

Hello list, I need to send to an external API events when user is registrated and de-registrated. As far as I understand standart behaviour is as follows: If user is not registered, he sends REGISTER and he is registrated (I can catch that because I make the auth). If user is registered and sends REGISTER he is de-register. (Please correct me if I'm wrong.) How can I catch that? Can I use event_route[usrloc:contact-expired]? Thanks in advance! -- Alexandru Covalschi ABRISS-Solutions VoIP engineer and system administrator tel: +37367398493 web: http://abriss.solutions/ <http://abs-telecom.com/>

Dialog timeout before answer

Hi, Will the dialog timeout - and specifically, $dlg_ctx(timeout_bye) - also apply to dialogs which have not yet been established? If so, does that mean the dialog module will send a CANCEL instead for a dialog in an early/progress state? -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Hi there, We use kamailio 4.3.3. And we have one problem with the fax. We send and receive from and to our network, the fax does not work. Fax reports "other fax not responding". When we send through our network to another operator they receive fax. What could be wrong?

Kamailio 4.3.3 and HUAWEI HG8245. Port 1 call port 2. 481 Call/Transaction Does Not Exist. Warning: 399 No Dialog match.
by Mx R 23 Jun '16

23 Jun '16

Hi there. In our network we used several ONT Huawei models. But with one model HUAWEI-EchoLife HG8245 / V1R003C00S205 we have the following problem. When connecting to this device in the POTS ports of the two phones. From the first port we can not call to the second and from the second port can not call to the first port. On the other ONT Huawei devices, there is no such problem. Earlier we had set OpenSIP and this device did not have a problem. The problem is likely in the configuration because it works at the default settings. kamailio -v Version: kamailio 4.3.3 (x86_64/linux) f69971 /var/log/kamailio May 17 10:53:21 kamailio /usr/local/sbin/kamailio[17875]: INFO: <script>: Callee '123456' is local -

Add a user through a http request
by Jay Li 22 Jun '16

22 Jun '16

Dear All, I wonder if Kamailio has the functionality to add a subscriber dynamically. For example, if I use event_route[xhttp:request] to expect a http get request, then based on the received request, add a user in the DB. Not sure what the best approach would be. Any suggestion is appreciated. Thanks. Regards,Jay

Dispatcher - Route call to alternate server if there is delay to answered call
by Amit Patkar 22 Jun '16

22 Jun '16

Hi I have a scenario where dispatcher is used to balance calls. Assume there are 2 media servers M1 & M2. Call are routed using round robin algorithm. There is scenario where call is handed over to M1 but it is not answered in defined time period (say 5 seconds due to load on server or network congestion), I wish to send this call to M2. What are the options to achieve it? Thanks & Regards, Amit Patkar

Hey Daniel, Thanks for so fast feedback! No difference as far as I can tell before and after removing the record from db.

WS to WS calls - No ACK received for 200OK
by Amit Patkar 21 Jun '16

21 Jun '16

Hi I am using Kamailio as Websocket proxy. User 1 & User 2 are registered on Kamailio over WebSocket. When User 1 calls User 2, User 2 gets ring and answers the call. 200 OK message is received by User 1 but ACK response sent by User 1 does not reach User 2. Since User 2 didn't get ACS, after 30 sec timeout it drops the call. Media is exchanged for 30 seconds, which means ICE is successful. I am running kamailio 4.3.3 on Kamailio is behind firewall and running on private IP. rtpengine is configured to handle media. All ports are forwarded to kamailio server and Kamailio is allowed to send data on any public IP. I used jssip & sipml framework to test. Result was same for both frameworks. No ACK received I can see following errors in log file. What could be the reason which indicate ACK was not forwarded Jun 21 14:55:41 acstemplate /usr/sbin/kamailio[6584]: NOTICE: acc [acc.c:317]: acc_log_request(): ACC: transaction answered: timestamp=1466501141;method=INVITE;from_tag=7926B9NR7U0X99ZfAr1T;to_tag=w3D2JGd2EUFJpobTcFyo;call_id=1edc8e15-f1f1-584d-df81-71c3d59d713d;code=200;reason=OK;src_user=10001;src_domain=xxxx.com;src_ip=xxx.yyy.zzz.aaa;dst_ouser=10002;dst_user=10002;dst_domain=df7jal23ls0d.invalid Jun 21 14:55:41 acstemplate /usr/sbin/kamailio[6582]: ERROR: <core> [forward.c:529]: forward_request(): cannot forward to af 2, proto 5 no corresponding listening socket Jun 21 14:55:41 acstemplate /usr/sbin/kamailio[6582]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) Jun 21 14:55:42 acstemplate /usr/sbin/kamailio[6584]: INFO: <script>: WS to WS Jun 21 14:55:42 acstemplate /usr/sbin/kamailio[6582]: ERROR: <core> [forward.c:529]: forward_request(): cannot forward to af 2, proto 5 no corresponding listening socket Jun 21 14:55:42 acstemplate /usr/sbin/kamailio[6582]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) Jun 21 14:55:46 acstemplate /usr/sbin/kamailio[6582]: ERROR: <core> [forward.c:529]: forward_request(): cannot forward to af 2, proto 5 no corresponding listening socket Jun 21 14:55:46 acstemplate /usr/sbin/kamailio[6582]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) Jun 21 14:55:51 acstemplate /usr/sbin/kamailio[6582]: ERROR: <core> [forward.c:529]: forward_request(): cannot forward to af 2, proto 5 no corresponding listening socket Jun 21 14:55:51 acstemplate /usr/sbin/kamailio[6582]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) Jun 21 14:55:57 acstemplate /usr/sbin/kamailio[6582]: ERROR: <core> [forward.c:529]: forward_request(): cannot forward to af 2, proto 5 no corresponding listening socket Jun 21 14:55:57 acstemplate /usr/sbin/kamailio[6582]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) Jun 21 14:56:13 acstemplate /usr/sbin/kamailio[6581]: ERROR: <core> [forward.c:529]: forward_request(): cannot forward to af 2, proto 5 no corresponding listening socket Jun 21 14:56:13 acstemplate /usr/sbin/kamailio[6581]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (7/SL) I searched list for similar issues but could not find match any Help to resolve this issue is appreciated.

21 Jun '16

Hello there, I need to use kamailio to consult an CNAM server in order to get the caller id name and number to the call, the diagram bellow represents what i need implement: Can I implement this behavior through the following kamailio modules: 1. tm and tmx module (call the function t_suspend and t_continue in order to stop INVITE transaction and resume it). 2. UAC module (generate the SUBSCRIBE sip message) 3. Some kamailio scripting logic to manage this behavior. what are your advices to implement this scenario? Thank you for your help Regards -- Cumprimentos José Seabra

RTPENGINE rtp errors
by Dmitry 21 Jun '16

21 Jun '16

Hi 1)I encountered such errors when I make an internal call between 2 yate client SIP softphones:rtpengine is used and no audio: | Jun 19 10:02:35 kazootest2 rtpengine[2066]: [918508371(a)kazootest2.siplabs.local port 30942] Error parsing RTP header: short packet (header) when I turn off the rtpengine:THe Freeswitch handles such RTP packets correctly and audio is ok. I compared manually rtp packets from Yate: they comply to the RTP specification. 2) A call from WS client(jssip) to an ordinary sip softphone: | Jun 19 09:58:36 kazootest2 rtpengine[2066]: [s2m2k70tu0d12bjnnamr port 30814] Error parsing RTP header: invalid header version | How to fix these errors? The rtpengine looks through all incoming packets while looking for a new RTP stream. May be packets parsing is too strict? |

Kamailio dispatcher module - keep alives
by José Seabra 20 Jun '16

20 Jun '16

Hello there, I have a Kamailio server using dispatcher module to monitor several peers, some of them are in the same network, others are in an external network, for the peers that are in the external network kamailio has to send the OPTIONS(dispatcher keep alives) through another kamailio located in the border and acting as loadbalancer. If i set the dispatcher option "outbound_proxy" all SIP OPTIONS are sent to the outbound proxy configured and it isn't what i need, I need to have by some way a possibility to set outbound_proxy only for the peers that are located on the external network. How can I do that? Regards -- Cumprimentos José Seabra

Why SDPOPS does not remove attributes in SDP
by Dmitry 18 Jun '16

18 Jun '16

Hi allI have the following code: if($T_reply_code=="200") { if(has_body("application/sdp")) { xlog("L_INFO", "RTPENGINE received internal reply $T_reply_code $rr SDP extra lines will be removed"); set_rtpengine_set("0"); rtpengine_manage(); sdp_remove_line_by_prefix("a=rtcp"); sdp_remove_line_by_prefix("a=ssrc"); sdp_remove_line_by_prefix("a=ice"); sdp_remove_line_by_prefix("a=candidate"); xlog("L_INFO", "RTPENGINE received internal reply $T_reply_code $rr SDP extra lines removed with SDPOPS"); } }When I look through traces - I see that 200 ok(with SDP) has all these attributes and they are not removed. Why SDPOPS does not remove these attributes?

Help with routing block and Dispatcher Module
by pablo rosales 17 Jun '16

17 Jun '16

Hi everyone! I am a newbie with Kamailio. I'm trying to connect a kamailio server to an asterisk gateway. We are using basic Kamailio 4.4.x configuration file with mysql and rtpproxy we are having same issues with dispatcher module. we can not call between local subscribers. Basically, If I call to a local subscriber, the module always execute the route(DISPATCHER) code on the routing block, trying to send the call to my gateway, but if I try to call to an external number, it works perfect. All calls are being send to my gateway. Here is my dispatcher code: # Dispatch requests route[DISPATCH] { # round robin dispatching on gateways group '1' if(!ds_select_dst("1", "4")) { send_reply("404", "No destination"); exit; } ### xlog("L_DBG", "--- SCRIPT: going to <$ru> via <$du>\n"); xlog(" --- DISPATCH: going to <$ru> via <$du>n"); t_on_failure("RTF_DISPATCH"); return; } ## Sample failure route failure_route[RTF_DISPATCH] { xlog(" --- DISPATCH: Starts RTF_DISPATCH \n"); if (t_is_canceled()) { exit; } # next DST - only for 500 or local timeout if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) { if(ds_next_dst()) { t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } } } Can anybody help to see what I am doing wrong??

Hi All, I tried today new module http_client. I just made GET request using http_client_query in following way: http_client_query("http://cool.api.com", "$var(result)"); It is working, but I can't see User-Agent in request. Below you can find my module options: modparam("http_client", "useragent", "kamailio") modparam("http_client", "connection_timeout", 1) Is it a bug, or am I doing something wrong? Thank you! Jurijs

Kamailio on multiple ports
by huseyin kalyoncu 16 Jun '16

16 Jun '16

Hello, We have kamailio running as proxy in front of a freeswitch box. This kamailio also acts as a registrar listening both 5060 and 5090 ports. We have two devices registered to kamailio: Device A on port 5060 Device B on port 5090 When Device B calls Device A everything is fine. Call released successfully. When Device A calls Device B, call setup is ok and they can talk. But when Device A tries to release the call, Device B remains open which cannot get a BYE message. When I dug up for the cause of the problem, I realized that: When Kamailo receives 200OK reply on port 5090 for the UPDATE message from Device B, it relays this reply internally and then sends this reply to freeswitch box on port 5060. This results in loosing alias in the contact field of the reply message and then which causes freeswitch to return BYE message with the wrong IP which is the local IP of the Device B. As a result this BYE message cannot be delivered to Device B. Is this a normal behaviour ? If it is so what changes should I make in the kamailio config to fix this? You can find the ngrep outputs of the both calls as attachment. Thanks Huseyin Kalyoncu
