Problems with avp_db_load
by Kevin Bushong 04 Apr '17

04 Apr '17

I am using the avpops module to read from a mysql database to look for CFWD information for the call. When a call is placed, it appears the command avp_db_load attempts to read the file but all values come back as NULL. There are no messages in the log and of course the call does not process correctly. We are using a config that is exactly the same on a 4.3.4 version of kamailio using cento 6.7, with a local version of mysql Ver 14.14 Distrib 5.1.73, that works perfectly. When moving the code to kamailio 4.4.4 on Debian 8, Jessie, mysql Ver 14.14 Distrib 5.5.53 the avp_db_load returns no information. Here is the snippet of the code we are using. Since I am not used to troubleshooting kamailio, please let me know what other information you need. Thanks, Kevin Code snippet: #!ifdef WITH_CFWD xlog ("$TF Call to $rU made it into WITH_CFWD in route[LOCATION] block\n"); # Call forwarding is enabled, so lets do a lookup to pull all AVP's for possible call forwarding types/destinations # Below line should load all AVP's into memory from DB for the username portion of the TO: field from table usr_preferences xlog("script should load from DB usr_preferences next"); avp_db_load("$tU","s/usr_preferences"); # This line i simple want to print to log when the avp load is complete and what the values are (for debug purposes only and should typically be commented out) xlog("DB load should be complete"); xlog("SCRIPT: $TF Call Forwarding Unconditional set to $avp(Unconditional)\n"); xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n"); xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n"); avp_print(); # Check to see if the AVP's are set and if so put them in log for logging purposes if(is_avp_set("$avp(Unconditional)")) xlog("SCRIPT: $TF Call Forwarding Unconditional set to $avp(Unconditional)\n"); if(is_avp_set("$avp(NoAnswer)")) xlog("SCRIPT: $TF Call Forwarding NoAnswer set to $avp(NoAnswer)\n"); if(is_avp_set("$avp(Busy)")) xlog("SCRIPT: $TF Call Forwarding Busy set to $avp(Busy)\n"); t_set_fr(16000, 15000); # set fr invite timeout to 16s and no response at all to 15s to meet the specs for call fowarding no answer ringtime # If Call fowarding Unconditional is set, we need to change the dialed number and sent it off to the original users trunk from subscriber table # Check to see if unconditional is set if(is_avp_set("$avp(Unconditional)")) # Shove this call into route [PSTN_CFWD] Block route("PSTN_CFWD"); Here is the syslog for the same snippet: 09:29 2017 Call to 15703771055 made it into WITH_CFWD in route[LOCATION] block Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: script should load from DB usr_preferences next Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: DB load should be complete Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding Unconditional set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding NoAnswer set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: ERROR: <script>: SCRIPT: Wed Mar 29 14:09:29 2017 Call Forwarding Busy set to <null> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1473]: ops_print_avp(): p=0x7f440ed86f90, flags=0x0113 Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1477]: ops_print_avp(): #011#011#011name=<direction> Mar 29 14:09:29 Limitless-Calling-Server /usr/local/sbin/kamailio[7831]: INFO: avpops [avpops_impl.c:1485]: ops_print_avp(): #011#011#011val_str=<INCOMING / 8>

Why these 2 items in the same entry for a htable
by Ginhoux, Patrick 04 Apr '17

04 Apr '17

Hi, While working on the project to migrate my kamailio.cfg script from kamailio 3.3.1 to 5.0.x, I discovered that in there are 2 items in the same htable. Below the figure that illustrate this case : 1) Content of the MBXRANGE table : mysql> select * from mbxrange; +-----+-------------+-------------------------------------------------+----- -------+----------+ | id | key_name | key_value | value_type | key_type | +-----+-------------+-------------------------------------------------+----- -------+----------+ | 0 | VERSION | 120104-173400 | 0 | 0 | | 101 | 1 | min=0100000000;max=0199999999;node=OPMVTS1VSE02 | 0 | 0 | | 102 | 2 | min=0200000000;max=0299999999;node=OPMVTS1VSE02 | 0 | 0 | | 103 | 3 | min=0300000000;max=0399999999;node=OPMVTS1VSE02 | 0 | 0 | | 104 | 4 | min=0400000000;max=0499999999;node=OPMVTS1VSE02 | 0 | 0 | | 105 | 5 | min=0500000000;max=0599999999;node=OPMVTS1VSE02 | 0 | 0 | | 106 | 6 | min=0600000000;max=0699999999;node=OPMVTS1VSE02 | 0 | 0 | | 107 | 7 | min=0700000000;max=0799999999;node=OPMVTS1VSE02 | 0 | 0 | | 108 | 8 | min=0800000000;max=0899999999;node=OPMVTS1VSE02 | 0 | 0 | | 109 | 9 | min=0900000000;max=0999999999;node=OPMVTS1VSE02 | 0 | 0 | | 199 | maxmbxrange | 9 | 0 | 0 | +-----+-------------+-------------------------------------------------+----- -------+----------+ 11 rows in set (0.00 sec) 2) modparam instruction used in my kamailio.cfg script: modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") 3) Result of < kamctl fifo sht_dump mbxrangeHash > command with kamailio version 3.3.x: [root@op52is4router1 ~]# kamctl fifo sht_dump mbxrangeHash Entry:: 0 6:: min=0600000000;max=0699999999;node=OPMVTS1VSE02 Entry:: 1 7:: min=0700000000;max=0799999999;node=OPMVTS1VSE02 Entry:: 2 4:: min=0400000000;max=0499999999;node=OPMVTS1VSE02 Entry:: 3 5:: min=0500000000;max=0599999999;node=OPMVTS1VSE02 Entry:: 4 2:: min=0200000000;max=0299999999;node=OPMVTS1VSE02 Entry:: 5 3:: min=0300000000;max=0399999999;node=OPMVTS1VSE02 VERSION:: 120104-173400 Entry:: 6 maxmbxrange:: 9 Entry:: 7 1:: min=0100000000;max=0199999999;node=OPMVTS1VSE02 Entry:: 14 9:: min=0900000000;max=0999999999;node=OPMVTS1VSE02 Entry:: 15 8:: min=0800000000;max=0899999999;node=OPMVTS1VSE02 Result of < kamcmd htable.dump mbxrangeHash > command with kamailio version 5.0.x : [root@vm-vse02-siprouter1 ~]# kamcmd htable.dump mbxrangeHash { entry: 0 size: 1 slot: { item: { name: 6 value: min=0600000000;max=0699999999;node=OPMMMS1VSE02 type: str } } } { entry: 1 size: 1 slot: { item: { name: 7 value: min=0700000000;max=0799999999;node=OPMMMS1VSE02 type: str } } } { entry: 2 size: 1 slot: { item: { name: 4 value: min=0400000000;max=0499999999;node=OPMMMS1VSE02 type: str } } } { entry: 3 size: 1 slot: { item: { name: 5 value: min=0500000000;max=0599999999;node=OPMMMS1VSE02 type: str } } } { entry: 4 size: 1 slot: { item: { name: 2 value: min=0200000000;max=0299999999;node=OPMMMS1VSE02 type: str } } } { entry: 5 size: 2 slot: { item: { name: 3 value: min=0300000000;max=0399999999;node=OPMMMS1VSE02 type: str } item: { name: VERSION value: 120104-173400 type: str } } } { entry: 6 size: 1 slot: { item: { name: maxmbxrange value: 9 type: str } } } { entry: 7 size: 1 slot: { item: { name: 1 value: min=0100000000;max=0199999999;node=OPMMMS1VSE02 type: str } } } { entry: 14 size: 1 slot: { item: { name: 9 value: min=0900000000;max=0999999999;node=OPMMMS1VSE02 type: str } } } { entry: 15 size: 1 slot: { item: { name: 8 value: min=0800000000;max=0899999999;node=OPMMMS1VSE02 type: str } } } So, I can see : - The entry number is not incremental 1 by 1 ; there are entry #1 to #7, then #14 and #15 (all have size=1) - For the entry #5, its size is of 2 and it contains 2 items I don't say here that this is a problem, but the way the htable is loaded seems strange to me. So if there people who can explain me if what I see is normal or not, and how the htable load process works, I would appreciate. Thanks in advance. Cordialement Patrick GINHOUX

Via header with i attribute
by DanB 04 Apr '17

04 Apr '17

Hey Guys, Any of you know which module is adding the "i" attribute and maybe if it can be removed safely? The reason would be for some Avaya PBXes discarding the Via completely due to this attribute. Sample header: """ Via: SIP/2.0/UDP 1.2.3.4;branch=z9hG4bKf0d6.72eca17f202d1e73a1f519dbecf7d6a6.0;i=8f1. """ Many thanks, DanB

Re: [SR-Users] ht_db_load_table(): key type must be string (type=6)
by Ginhoux, Patrick 04 Apr '17

04 Apr '17

Hi, A second update for people who started to look at this issue. I have identified the real cause of the problem by looking more in the kamailio log with the debug traces. I discover that it is related to the load of the properties table in the htable. I have the following entries in my mysql db : +-------+----------------+---------------------------------------------------------+------------+----------+ | id | key_name | key_value | value_type | key_type | +-------+----------------+---------------------------------------------------------+------------+----------+ | 0 | VERSION | 120104-1734 | 0 | 0 | | 1 | mmm-retry | 408=Y;502=Y;503=Y | 0 | 0 | | 2 | mgcf-retry | 408=Y;502=Y;503=Y | 0 | 0 | | 3 | max-mmm-retry | 2 | 0 | 0 | | 4 | max-mgcf-retry | 2 | 0 | 0 | | 5 | target-uri | mgcf=10.10.10.10;mmm-legacy=20.20.20.10;mmm=20.20.20.20 | 0 | 0 | | 6 | pike-status | 503 Service Overload | 0 | 0 | | 7 | mgcf-path | 99 | 0 | 0 | | 16 | mmm-nodeid | OPMMMS1VSE01=1;OPMMMS1VSE02=2 | 0 | 0 | | 17 | mmm-node-path | 1=1;2=2 | 0 | 0 | +-------+----------------+---------------------------------------------------------+------------+----------+ In the kamailio.cfg, the << modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") >> command causes the load of the above table in the htable. In the log we can see, that the load is done in the alphabetic order of the key_name and it fails to load the last entry "VERSION" : Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [VERSION] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [120104-1734] Mar 21 10:25:28 localhost /usr/sbin/kamailio[5784]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6) If I add a new entry named "WWWWW", then the failure occurs on this entry that is the last alphabetic entry : | 10000 | WWWWW | toto | 0 | 0 | Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [WWWWW] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:74]: db_str2val(): converting INT [0] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: DEBUG: <core> [db_val.c:169]: db_str2val(): converting BLOB [toto] Mar 21 10:28:45 localhost /usr/sbin/kamailio[5817]: ERROR: htable [ht_db.c:276]: ht_db_load_table(): key type must be string (type=6) Attached the kamailio log for each test.

My first attempt (see kamailio.cfg.ok) shows that the problem doesn't occur. In the second attempt (see kamailio.cfg.ko) I add instructions previously removed from the original .cfg file. I have determined that, depending on the instructions that follows the "modparam("htable", "fetch_rows", 1000)" line, the "key type must be string (type=6)" error occurs or not. In this ko file, if I comment out the following sequence, the error occurs : modparam("htable", "fetch_rows", 1000) #!!ifdef FIXED_ROUTING #modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") #!!else #modparam("htable", "htable", "abpqHash=>size=12;dbtable=abpq;") #modparam("htable", "htable", "zabpqHash=>size=12;dbtable=zabpq;") #!!endif modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") I hope my explanation is clearn and there are people who can help me on this problem that causes kamailio to not start.

Doubt parsing multipart SDP
by Albert Petit 03 Apr '17

Hi list, I am having some issues parsing multipart INVITE [1] when calling force_rtp_proxy . I tried to upgrade to Kamailio 5 to see if maybe i was using too old code but seems not the case. Log of error is: Apr 3 18:31:21 mcptt /usr/sbin/kamailio[3232]: INFO: <script>: forcing RTP proxy for INVITE message Apr 3 18:31:21 mcptt /usr/sbin/kamailio[3232]: ERROR: <core> [core/parser/parse_content.c:370]: decode_mime_type(): ERROR:decode_mime_type: parse error near in [application/vnd.3gpp.mcptt-info+xml] char[51][3] offset=16 So seems there is some issue using Content Type application/vnd.3gpp.mcptt-info+xml in a multipart SIP message But this content type is accepted at following 3GPP spec: http://www.etsi.org/deliver/etsi_ts/129100_129199/129165/13.06.00_60/ts_129… Checking implementation of parse_content.c I see ". - _ +" characters are accepted so i am not sure what is failing. I did some test and if instead of that Content-Type: application/vnd.3gpp.mcptt-info+xml i use Content-Type: application/mcptt no errors are seen in Kamailio logs and ports are replaced succesfully. So do you see something wrong on what i am doing with attached info?

Doubt about MI Datagram module in Kamailio 5
by Albert Petit 03 Apr '17

03 Apr '17

Dear list, I've recently upgraded to Kamailio 5 in order to avoid issue parsing SDP multipart bodies which think are fixed in the update ( - symbol rejected in content type) . I could upgrade without issues from my kamailio 4 dev deployment but i cannot load anymore MI_Datagram module (seems not present in Kamailio 5 , MI Datagram module i refer to: http://www.kamailio.org/docs/modules/4.3.x/modules/mi_datagram.html ) Can i use MI Datagram module still in Kamailio 5 ? Thanks Albert

Exclusive: Quitting the fast life of open-source SIP
by Alex Balashov 03 Apr '17

03 Apr '17

(Filed by UC Celeb Talk - 1 Apr 2017.) BERLIN (Tegel), GERMANY--In the now-infamous breakdown episode on the VIP tarmac at Berlin's Tegel Airport, Alex Balashov shocked the IP telecoms celebrity world last month. Shielding his eyes from the punishingly bright daylight of an overcast day in northern Germany, Balashov climbed out of his Gulfstream G650 jet, clutching a half-finished bottle of Woodford Reserve, and announced his sudden retirement from the "fast life" of open-source SIP consulting to a waiting gathering of techn business reporters. "I'm not with this 'live fast, die young' VoIP s*** anymore," he reportedly shouted, before collapsing and vomiting profusely on the red carpet. UC Celeb Talk's own Benjamin Brant sat down with Balashov in an exclusive interview to learn more about what happened, even as the telecoms industry continues to digest the shock meltdown. -- BRANT: Everyone's dying to know, what was going through you head at that moment? BALASHOV: Funny how you mention dying. I want to live to see 35, man. I can't handle the SIP biz anymore. BRANT: What do you mean? You seemed to have all the makings of an open-source SIP superstar. BALASHOV: I can't keep up with the drinks anymore, the three day-long parties, the paparazzi, always watchin' my back at ClueCon... BRANT: When'd you realise it might be time to call it? BALASHOV: I'll tell you when. It was Kamailio World '16. Man, those vodka + Club Mate drinks they pour down at Fokus are something else. They'll really get you thinking about things. BRANT: So you had a cocktail and thought better of your entire life as a SIP celebrity? The fans, the adulation, the glory? BALASHOV: When you wake up at 3 PM at the Park Inn on Alexanderplatz with a $31,000 room service bill on your AMEX, a goat wandering around, and reporters in your face, you tell me with a straight face you're not gonna take stock of your life and make some changes. BRANT: That really happened? BALASHOV: That's what I'm trying to tell you! That's Kamailio World, dude. That's the SIP software engineering culture. You wanna ITSP and WebRTC? You're gonna have to bro down! BRANT: Surely not everywhere. What about the IETF? BALASHOV: Those guys drink more than ANYONE. Have you seen the SIP Outbound RFC? BRANT: That's the work-product of an alcohol-fuelled creative orgy? BALASHOV: It's the work product of something-something. I don't know if I'm allowed to identify the uh, substance in question. BRANT: How are you going to live without the private jet? If I had a G6, I wouldn't just turn over the keys. BALASHOV: Yeah, I mean, open-source VoIP consulting has its upsides. It's a fine way to make a living. But it's just not worth it. Besides, hourly operating costs are through the roof. BRANT: But you were an icon, and quite a ladies' man too! How do you walk away from that? BALASHOV: Look man, of course women are gonna mob you when you're a SIP consulting star. That's just part of the open-source tech life in general. But it's fake, man. They don't love you. They don't want to know who you are inside. They just want you 'cause you know all about the SIP transaction state machine, loose vs. strict routing, cross-compiling Kamailio. They just got a crush on you 'cause you know presence and parallel forking race conditions. I want something real. BRANT: But that's part of the social bargain of being an open-source SIP celebrity. Didn't you once boast of having uh, lady friends, "in different geographic and non-geographic operator codes"? BALASHOV: Yeah, and that's cool, but I want to come home to a woman who loves me for me, not Mr. 3... ... 02, Moved Temporarily, but not happy necessarily. Feel me? BRANT: What happened at ClueCon? BALASHOV: You talking about the bullets Acme Packet ventilated me with? BRANT: Five of them, as I heard. BALASHOV: Well I'm still standin'. Took those shots and smiled. BRANT: I know you guys have a kind of omertà about this stuff, but I've got to ask: why? BALASHOV: I ain't worried, kids growing up in today's world need to learn the truth. They act like I was dealing transcoding licences on their block. O.G. 729. BRANT: But that wasn't what gave you a wake-up call that the SIP game is sharper than a razor blade? BALASHOV: Hell no, it wasn't their block. That fake-ass east coast channel partner crew can cash me outside howboudah? BRANT: How exclusive is Kamailio World? BALASHOV: It's one of the most exclusive clubs I've ever hit up. Lines wrapping around blocks. And the bouncers. Damn. BRANT: The bouncers? BALASHOV: Those dudes are harsh. BRANT: On a scale of 1 to Berghain, how bad is it? BALASHOV: All I know is, one time some squirrely guy in the audience asked a moderately new-blood question like, "If a Record-Route header has been added by an intermediate proxy, is it proper of a SIP User Agent to populate the Request URI of subsequent in-dialog requests with the Record-Route URI, or should it be the remote Contact?" Half the room got up like it was ready to curb-stomp that little face. Guy didn't know what he got himself into--a room full of elites. BRANT: So what happened? BALASHOV: Someone was like, "Bounce this fool! He don't know how to act." So these three muscular Kaiser Wilhelm-looking dudes--moustaches and all--in sunglasses roll up and drag this guy through the Atrium, out the doors and dump him straight out onto Anna-Louisa-Karsch-Straße. BRANT: Damn. Ejected out of the saloon. BALASHOV: Yo, that dude was dismissed from the premises. BRANT: So what do you see in your future post-SIP life? BALASHOV: I'm thinking about starting a bakery. A friend threw it out there as a way to kind of atone for all this and get straight with Jesus. Gonna bake really big cookies. You know, huge ones, like a small pizzas? But recognise--they're actually cookies. BRANT: Got any advice for those who bright young upstarts who haven't turned over a new leaf and thrown in the towel yet? BALASHOV: Come on down to Kamailio World #5, May 8-10 2017 in Berlin. You'll see your life in a new way. Registration and more information online at https://www.kamailioworld.com/k05/

Kamailio 6.0 architecture
by Olle E. Johansson 03 Apr '17

03 Apr '17

Dear Kamailians! We got news for you! The Kamailio 6.0 architecture is finalised! It's something we've been working on for a long time in the project team and you've already seen part of it in the recent Kamailio 5 release - the KEMI interface for LUA. We've realised that we have too many modules, especially all those IMS* modules. And the core is getting slimmer and slimmer. This is what we're going to do: * All RPC, EVENTAPI,AUTH, JSON, TM, HTTP_CLIENT and TLS modules will be integrated back into the core. * The EVENT API will be the core API for external modules * The rest of the functionality in the modules will have to be rewritten in LUA and maintained as separate GITHUB projects outside of the core After successfully integrating LUA into the heart of Kamailio and exposing the Kamailio API we have decided to make life more simple for the core maintainers. Maintaining well over 100 modules took too much time, and who cares about some of the stuff? Billing, least cost routing and all the other crazy stuff in modules are going away anyhow as all services will be free. Calls really wants to be free. And presence is no longer needed, we'll just tap into the mobile phones from the core to know where everyone is. The removal of the modules will take place during the month of April 2017 and a new core will raise like a Fenix from the ashes, a much larger, monolithic and complex core with new functionality that will take Kamailio to new areas, like a message bus for games, an API server for mobile yoga apps and a control plane for embedded IoT devices. "Kamailio everywhere" is the new slogan for the Kamailio project. - "We will all remember April 1st 2017 as a new start of the project" says Olle-Carsten Mierla, the new elected project leader. "From now on, Kamailio aims to be a standard part of every operating system distribution, defining the new core of the Internet.” We hope all of you join us in this effort and refrain from reporting any bugs or other disturbing issues while we rebuild the new Kamailio. /O

Configuring Kamailio as a "VoIP traffic reflector"
by Tahiro Hashizume 31 Mar '17

31 Mar '17

Hi there, This e-mail is going to be lengthy and I hope you will not get frustrated (like I am, for different reasons described later) by reading it all from the beginning to the end since I have just warned you :P You have absolutely no need for reading the entire post unless you are crazy enough read about what I do for fun in given circumstances. Basically, I would like Kamailio and Asterisk to run on the same box in such a way that A.)Asterisk listens on eth0 (on 10.1.1.15/24 with ProxyARP enabled) for incoming SIP register requests from VoIP-ATAs B.)Kamailio listens on five IP addresses on dummyN which has 10.1.1.1N/32 (N=0-4, so dummy0 has 10.1.1.10/32, for example) making five SIP+RTP sessions to the same remote host to appear as if they are from five different hosts - so that a single instance of Asterisk running on debian may be registered (through Kamailio) on the same remote host by using five different accounts and source IP addresses. I know Asterisk alone cannot do this (even by running multiple instances of it) and that there have to be five instances of both SIP-Proxy and RTP-Proxy so that the source address can be literally spoofed. Should be simple, but so far cannot find good sources of reference. I need your advice. Thanks in advance. << Backgrounds - read only if you are curious >> The so-called frustration is when your needs are not realized due to technological limitations. I have years worth of frustration on the VoIP setup at home and that's totally NOT your fault. Written below for those who happen to be curious should sound interesting, so here is the situation I'm facing; I'm in Japan and our infrastructure is well within the definition of NGN which in my case includes a low-latency VoIP to replace the traditional PSTN. (NTT will end ISDN in 2020, copper-line PSTN in 2025, as announced so far.) The service is provided by NTT (former state-run telecom) of Japan and works on FTTH which carries: a.)PPPoE for those who wish to get IPv4&IPv6 connectivity - which for the most part is so that users get to choose their favorite ISP. b.)WAN-reachable IPv6 traffic c.)WAN-unreachable IPv4 for SIP based services (address blocks reserved and announced by AS9595) Given the fact that b.) and c.) are only applicable (optionally and respectively) to those who signed up for the native-IPv6 (we call it IPoE, oddly) service and to those who signed up for the VoIP service, it's essentially an L2 transport service for PPPoE to your ISP - very much like the way we had our phone-line and ISP (dial-up) separately signed up for in the old days (hence I call it the access-line service). I've made a switch over to VoIP-based PSTN from the copper-line in April 2011 after seeing that copper-line PSTN served no better in case of emergency like 3.11 when people want to call others to see if their loved one are okay - on the evening through the night of March 11 2011, our traditional PSTN stayed at its capacity limits while VoIP-based means of communication (incl. Skype, surprisingly) stayed intact. That was the wake-up call. Now, upon signing up for the VoIP service, the user receives a box so called HGW (stands for Home Gateway) which is very much a SIP+RTP UA on its WAN side and SIP+RTP server on LAN side (up to 5 UAs may register if the UA supports "sip session-timer"). And this HGW is being the pain that drove me to writing this e-mail - it only allows one SIP-register per IP address. Further, looking into the specs requirements for HGW published by NTT (=there's a centralized documentation for it since the designs and manufacturing of HGW is split across several companies), there's a part which basically says: "One SIP register to HGW from a UA on LAN should be able to handle (but not limited to) one data session. An UA on HGW's LAN side may support multiple-data session per SIP register(optional)." - which to me reasonably explains why my HGW only allows one SIP-register per IP address. My gyess is that the unwritten assumption here is "one sip register"="one physical phone", which is quite understandable. Regarding the fact that NTT optionally provides services like: 1.)additional phone numbers 2.)multi-data sessions(RTP for voice, for example) ...on one trunk. This, and also in accordance with the technical specs. requirements for HGW above means supporting multiple RTP sessions either terminated or originated by an Asterisk box which sits on the HGW's LAN side requires that a single instance of Asterisk on a debian box somehow uses multiple IP addresses (with or without the use of other software). The simplest way of doing this (to me) seemd like running five instances of RTP(proxy)+SIP(proxy) which will each listen on one of five IP addresses, to which the Asterisk instance in question could establish one session of SIP+RTP each. The idea seemed simple enough, but there did not seem like good selections of software years ago. I have once given up on the implementation years ago, altered the NTT-supplied HGW with a third-party product (NVR500 by YAMAHA which on its LAN behaves as a MGCP+RTP server) in order to maximize the stability of the phone system. This was due to the fact that the x86-box I was using was hardware-unstable and that the HGW's behavior was something I did not like dealing with (recently solved). I've decided to make a come-back to Asterisk recently since I recently started using hylafax running on a RasPi with RS232 modem hooked up to it but with missing support for CID since the Japanese equivalent of CID (we call it Number-Display) does not follow the Bellcore standards and the modem I use only supports Bellcore standards- going VoIP again and running iaxmodem could solve this issue. -------------------------------------------- Tahiro Hashizume Department of Electrical and Electronic Engineering at Tokyo Denki University 5 Senju-Asahi-cho Adachi-ku Tokyo, JP1208551 Japan --------------------------------------------

log_custom module question
by Anonim Stefan 29 Mar '17

29 Mar '17

Hi, I'm trying some logging via UDP, using log_custom module. I've noticed that the logs are always sent through the first interface in the config "listen=" rows. Now, is there a way to listen on that interface, in order to log_udp() on it, without being able to send/receive any SIP on it? (i.e. disabling SIP capability and use it only for logging via UDP) Thank you, Stefan

Kamailio Registration load Issue
by Jade SZ 28 Mar '17

28 Mar '17

Hi Guys, I am running a simple REGISTER load test on: 1) Kamailio sever with 2 cores - mem 5G 2) Kamailio server with 4 cores - mem 16G Both are EC2 instances. At -r = 500 i.e. 500 reg/sec sipP test works fine with very few re-trans. But when i increase it to 800 reg/sec it starts retransmissions in bulk. I don't see server's CPU, load-avg or memory shooting. Running everything by default, even using kamctl to start the instance. So I have not tuned any params yet. My main concern is how can I make server choke and get its actual capacity, and avoid these retransmissions as apparently kamailio is not even utilizing 2 cores and CPU usage is under 10 always. Results of both server is same i.e. 500 reg/sec max so I am sure there is some problem that needs a fix, but need some hints here. Also used multiple SIPp's to rule out if it is SIPp issue, but after 500 I see same problem. Regards, JSZ

new keepalive module ?
by Guillaume Bour 28 Mar '17

28 Mar '17

Hi all, I would like to implement destinations keepalive in drouting module (as it is done in dispatcher). But instead of duplicating what's implemented in dispatcher, I think it would be more clever to create a new module dedicated to pinging destinations, and to plug drouting, dispatcher and other modules to this new one What's you opinion about that ? Cheers, Guillaume

Presence + RLS + XCAP
by Paul Smith 27 Mar '17

27 Mar '17

Hi I am struggling to figure out how to build and test an integrated presence server with Resource-List (rls.so) and XCAP (xcap_server.so). I am confused about what is meant to happen and how to debug it. Not sure if I am suffering from incompatibilities, configuration errors, or bugs… I have not found an up to date guide on configuring an integrated presence, rls, xcap server so I have used old tutorials, module documentation and some course code review … but I’m pretty confused now! I am using Snom phones and Jitsi (on Mac) to test. I have a kamailio Registrar which proxies all presence messages to the separate kamailio 4.2 Presence server. REQUIREMENT : Contact Presence ============================= I would like to get a SUBSCRIBE from the Snom phone to subscribe to a contact-list resource list, and to receive a NOTIFY with all of the presence states for those contacts. Relevant snom settings? Contact List URI: this generates a SUBSCRIBE with event:presence I believe that: ========== presence module should be managing the individual user presence and dialog states xcap module should allow me to use HTTP / curl to edit the resource lists rls module should be managing the mapping from a resource list subscription to the individual presence states and generating the aggregated NOTIFY messages. each device should then be able to SUBSCRIBE to a resource list uri and then receive an aggregated NOTIFY for all of the watched entities. Current status: =========== SUBSCRIBE sip:org1a-contacts@*****.co.uk SIP/2.0 v: SIP/2.0/UDP 192.168.1.15:59594;branch=z9hG4bK-qllzlgs3xf43;rport f: <sip:org1a@*****.co.uk>;tag=wwasqc6lmb t: <sip:org1a-contacts@****.co.uk> i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 1 SUBSCRIBE Max-Forwards: 70 User-Agent: snomD375/8.9.3.46 m: <sip:org1a@192.168.1.15:59594>;reg-id=1 Event: presence Accept: application/pidf+xml, application/rlmi+xml, multipart/related Supported: eventlist Expires: 3600 l: 0 … auth handshake SIP/2.0 202 OK Record-Route: <sip:10.210.160.13;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes> Record-Route: <sip:**pubip**;r2=on;lr=on;ftag=wwasqc6lmb;nat=yes> v: SIP/2.0/UDP 192.168.1.15:59594;received=**recvip**;branch=z9hG4bK-8wufiv1ua3ne;rport=60554 f: <sip:org1a@****.co.uk>;tag=wwasqc6lmb t: <sip:org1a-contacts@*****.co.uk>;tag=a6a1c5f60faecf035a1ae5b6e96e979a-d30e i: 313439303236383530323234313530-x3hlb3j6b5ef CSeq: 2 SUBSCRIBE Expires: 3600 Contact: <sip:10.210.160.16:5060;transport=udp> Server: kamailio (4.2.0 (x86_64/linux)) Content-Length: 0 … and then the snom receives an empty NOTIFY.

Is that correct? There is noting in rls_watchers or rls_presentity tables. Should there be? I have a rows in the XCAP table for the Resource-List curl -d @/tmp/contacts-resource-list.xml -vvv -X PUT http://109.104.108.23:5060/xcap-root/resource-lists/users/sip:org1a-contact… relevant row in xcap table: | 3 | org1a-contacts | *****.co.uk | <?xml version="1.0" encoding="UTF-8" standalone="no"?><resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists"><list name="team"><entry uri="sip:1002@****.co.uk"/><entry uri="sip:1001@****.co.uk"><display-name>bob</display-name></entry><entry uri="sip:1003@****.co.uk"><display-name>test1</display-name></entry><entry uri="sip:1006@****co.uk"><display-name>test1006</display-name></entry><entry uri="sip:1007@****co.uk"><display-name>test1007</display-name></entry><entry uri="sip:1008@h****.co.uk"><display-name>test1008</display-name></entry><entry uri="sip:1009@****.co.uk"><display-name>test1009</display-name></entry> <entry uri="sip:1005@****.co.uk"><display-name>testing1005</display-name></entry> <entry uri=“sip:org1a@****.co.uk"><display-name>testingorg1a</display-name></entry> <entry uri=“sip:org1c@****.co.uk"><display-name>testingorg1c</display-name></entry></list></resource-lists> | 4 | sr-1490270411-10965-2 | 0 | /xcap-root/resource-lists/users/sip:org1a-contacts@****co.uk/index | 0 | I have rows in the presence table for the entities that I want to track e.g. | | | 2889 | org1c | ****.co.uk | presence | a.1490270411.10942.42.1083 | 1490277099 | 1490273499 | <?xml version="1.0 " encoding="UTF-8"?> <presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:im="urn:ietf:params:xml:ns:pidf:im" entity=“pres:org1c@*****.co.uk"> <tuple id="snom370-000413260935"> <status><basic>open</basic> <im:im>Available</im:im> </status> <contact priority="1.00">sip:org1c@****.co.uk</contact> <note xml:lang="en">Available</note> </tuple></presence> I am running kamaiio 4.2 Question : Should I have an resource-services row too? Or does rls.so infer the relationship using the URI? When I use jitsi to manipulate its contact list it only inserts 2 rows into the xcap table and I cannot get a SIP Subscribe to connect to that resource list either. Question : What should the curl PUT commands and XML docs look like to build a valid RLS service (is there a good example anywhere)? Question : Is there an example config or doc anywhere showing how to build integrated presence, rls, xcap? Question : Has anyone got this working with Snom and or other handsets… the standards and implementations seem vague / inconsistent? Note: There is another Snom setting (Extension Monitoring Call Pickup List URI:) which produces a SUBSCRIBE with Event:dialog but which should allow a button/lamp/callpickup/BLF for the buddy contact. I’d like to get that working too, but recognise that rls.so does not handle dialog messages by default, so I’m starting with Presence... Paul

Important problem with this test : if ($var(i:maxRangeInx)==$null)
by Ginhoux, Patrick 27 Mar '17

27 Mar '17

Hi, I'm continue my job to 'migrate' my 3.3.1 kamailio.cfg script on a RHEL 6.2 server to the 5.0.x kamailio version on a RHEL 7.1 server, and I encounter a major problem with the '== $null' test in the script. My original script (3.3.1) contains this sequence : $var(i:rangeInx)=0; $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange"); xlog(" imbxRangeInx value before test : '$var(i:maxRangeInx)' "); if ($var(i:maxRangeInx)==$null) { $var(i:maxRangeInx)=99; } xlog(" imbxRangeInx after test : '$var(i:maxRangeInx)' "); ==> The results are : imbxRangeInx value before test : '0' imbxRangeInx value after test : '99' I run the same script on my new server and I get '0' before and after the test. I attempted another kind of test to try to figure out where the problem is. So I write the simple test (with kamailio 5.0.x) : $var(i:rangeInx)=0; $var(i:maxRangeInx) = $sht(mbxrangeHash=>"maxrange"); $var(toto) = $null; if ($var(toto) == $null) xlog ("toto true"); else xlog ("toto false"); The result I got is always 'toto false'. So it appears to me that the test '== $null' doens' that gives a good result with kamailio 3.3.1, doesn't return the same with kamailio 5.0.x. That is a major issue for me and it let me confused about the possibility to move to kamailio 5.0.x. Have people an idea / explanation, why this issue ? Cordialement Patrick GINHOUX

Cannot yum download from download.opensuse.org, no mirrors
by Shadowy Man 27 Mar '17

27 Mar '17

This is only happening for one particular block of IP's. I can download from other blocks. I suspect it is being done on the download.opensuse.org end for some reason. It appears to be the entire xx.xx block of which I only use a few addresses from. I will probably have to try contact them about it. What I would like to ask is why Kamailio does not have any mirrors? If there were then this would not be a problem. It would just failover.
