Kamalio & Asterisk integration erroneous behavior, setup issue
by Aristeidis Tsitras 05 Sep '19

05 Sep '19

new to the area and trying to setup Kamailio with Asterisk in a single machine. All users will register to Kamailio's port and in case of need for media, it will be forwarded to Asterisk, that is my intention. All of my work is based on the following link https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb. Here is what i have done: - Debian 8, 64 bit machine with mysql and odbc - *root@kamast: ~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 8.11 (jessie) Release: 8.11 Codename: jessie root@kamast: ~ $ uname -a Linux kamast 3.16.0-10-amd64 #1 SMP Debian 3.16.72-1 (2019-08-13) x86_64 GNU/Linux root@kamast: ~ $ * - Kamailio 5.2 installed from Kamailio's deb repository - Asterisk 13LTS installed from source - Used the same passwords such as kamailiorw and asterisk_password, since this is a test system, for proof of concept. I did import to the mysql>asterisk database 3 users 2200, 2201 and 2202. Then created in sip.conf the same 3 users with the same credentials. Then on 3 PCs i used softphones (Jitsi, Zoiper) and registered each account to a softphone. Problems: - Cannot see the users in the Asterisk's cli, sip show peers - I can see users only in Kamailio with kamctl ul show - A call between the extensions goes to voicemail. It never reaches the other destination eg 2200 calls 2201 and in Asterisk's console i am getting a message that 2201 is absent and it goes to voicemail. The same with any other extension. Attached you can find: 1. Kamailio.cfg 2. Asterisk's sip.conf 3. Asterisk's extension.conf 4. The import that i have done to mysql for the user creation. I would appreciate if someone could point me to the error and help me fix it please?

$Au being set to $fu instead of $fU
by Joel Serrano 05 Sep '19

05 Sep '19

Hi, Testing on latest master deb nightly build from last night I've noticed that when $au is not available, $Au is being set to $fu (uri) instead of $fU (username). Docs: https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables ... $Au - Acc username: username for accounting purposes. It's a selective pseudo variable (inherited from acc module). It returns auth username ($au) if exists or From username ($fU) otherwise. ... I have the following log in several places in a test box: xlog("L_NOTICE", "[DEBUG] Au=$Au au=$au aU=$aU fU=$fU fu=$fu - \n"); And when I run through them (on both request and reply routes) I get the following: Aug 8 14:37:43 csbc01 csbc[9478]: NOTICE: {1 21564 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=<null> aU=<null> fU=1002366 fu=sip:1002366@some.domain - Aug 8 14:37:43 csbc01 csbc[9479]: NOTICE: {1 21565 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=1002366 aU=1002366 fU=1002366 fu=sip:1002366@some.domain - Aug 8 14:37:43 csbc01 csbc[9484]: NOTICE: {2 21565 REGISTER d8df9be1-1702e20b(a)A.B.C.D} <script>: [DEBUG] Au=1002366(a)some.domain au=<null> aU=<null> fU=1002366 fu=sip:1002366@some.domain - Those 3 logs belong to the same flow from different places in the config script. I would expect $Au to never have a "@some.domain" in it, so I assume in some place the replacement is not being done with $fU but with $fu. @Devs: I'm happy to create a GH issue for tracking etc if required, please let me know! Cheers, Joel.

How to detect miss call and accomplished call
by Anuran Barman 05 Sep '19

05 Sep '19

Hi, I want to show call logs in my SIP app. How can I do this with Kamailio? I want to do it from the *kamailio.cfg *file. Is it possible to do it from where? I guess Dialog module should be used for this, but can not figure out how to do it. I want minimalist feature like who call whom with timestamp, thats all. How can I do this?

Planning the next major release - v5.3.0
by Daniel-Constantin Mierla 04 Sep '19

04 Sep '19

Hello, it's about the time to set the milestones to the next major release - v5.3.0. There are 6 new modules and many other enhancements to existing components in git master branch, also during the last irc devel meeting it was proposed to freeze after summer holidays. At this moment I would propose Wednesday, September 4, 2019 to freeze the development. Then the release should be about one month later, after testing interval. In case there are people willing a bit more time for development, we can freeze one week later, September 11, or another date -- your suggestions here.

Using Kamailio IMS for making a call
by supreeth herle 04 Sep '19

04 Sep '19

Hello Everyone, I have successfully setup a VM in OpenStack with Kamailio IMS, rtpengine and FoHSS using the instructions mentioned in the guide which i wrote (attached to this mail), all running in the machine. I am using the existing alice and bob IMPUs created in FoHSS. But, when I try to call each other the call doesnt go through and I observe in the wireshark traces that S-CSCF is replying to I-CSCF that "403, Forbidden - Domain not served". Can somebody please tell me do I need any additional components to make a call or am i missing some configuration? It would be great if someone can help me troubleshooting this issue. I have attached the pcap file for your reference. Many thanks in advance. Regards, Supreeth

Kamailio stops processing requests over UDP
by Juha Heinanen 04 Sep '19

04 Sep '19

I'm returning to an old issue, where Kamailio stops processing incoming requests. Now it turned out that only requests over UDP are not processed. Requests over TCP work fine. Debug log doesn't show anything about the requests over UDP, but wireshark sees them coming. core.ps shows that main process - attendant and all udp receiver processes are alive. Any ideas what could cause Kamailio (5.2 version) to stop processing requests over UDP? What additional info should I try to get? -- Juha

Hello Group - I have a "challenge"
by Kevin Greene 04 Sep '19

04 Sep '19

I recently did the upgrade from v4.4 to 5.2 (via Yum). When starting Kamailio, I get these three errors. Not sure if they are related or not but I do not think so. Have spent a lot of time searching on Google for the answer and have not found the solution. [root@ids kamailio]# kamctl restart INFO: Stopping Kamailio : INFO: stopped INFO: Starting Kamailio : INFO: started (pid: 44608) [root@ids kamailio]# tail -f /var/log/sipserver.log Sep 4 00:39:06 ids /usr/sbin/kamailio[44608]: ERROR: <core> [core/pvapi.c:1119]: pv_parse_spec2(): wrong char [t/116] in [$mt] at [2 (0)] Sep 4 00:39:06 ids /usr/sbin/kamailio[44608]: ERROR: <core> [core/dprint.c:451]: log_prefix_init(): wrong format[{$mt $hdr(CSeq) $ci} ] Sep 4 00:39:06 ids /usr/sbin/kamailio[44626]: ERROR: <core> [core/receive.c:319]: receive_msg(): no request_route {...} and no other config routing engine registered The last error is repeated many times (each time a remote user tries to connect I think). I can send any additional files if needed. Thanks. I am burning out on this upgrade. Kevin

Unexpected BYEs from dialog module
by Alex Balashov 03 Sep '19

03 Sep '19

Hi, I am running 4.3.5:1b0c0a, which I am aware is an EOL'd release train, and have a problem with the dialog module I am baffled by. On many calls - I can't find any correlation to particular kinds of endpoints - I see spoofed BYEs come out of Kamailio after a minute and a half, as if the call had hit a dialog timeout or the dialog module's dead peer detection (OPTIONS pinging) kicked it out. The thing is, neither of those explanations seem to be borne out by the parameters of the calls under investigation. The dialog timeout on these calls is set to 7200, and the dialog keepalives aren't enabled in either direction. If they were, it'd be logged. Calls that are terminated in this manner also see the following log message: WARNING: dialog [dlg_req_within.c:214]: bye_reply_cb(): inconsitent dlg timer data on dlg 0x7f9997317e48 [3390:9644] with clid '1996679936_133218050(a)x.x.x.x' and tags '2bb17663-co4006-INS001' 'as7925780d' But I don't think this is unusual for a dialog-spoofed BYE; presumably this is due to a 200 OK for the BYE from both ends. So anyway, I am trying to track down anything else that could inadvertently cause dialog to hang up calls relatively quickly in that release, or inadvertently set the dialog timeout parameter to something lower than is apparent from the logging and the config. If anyone has any pointers, that would not go unappreciated!
