Debugging kamailio module
by Ali Shirvani 23 Jul '19

23 Jul '19

Hi all, I want to trace function calls in a kamailio module, e.g. ims_isc module. I installed kamailio-dbg package and started the kamailio with gdb: `gdb kamailio` I also set break point on target function, but it seems gdb doesn't stop on that break point. How should I start gdb and set break points? it seems gdb couldn't handle kamailio child processes that forked in start. Regards, Ali

Two GWs with the same IP
by Duarte Rocha 22 Jul '19

22 Jul '19

Greetings, I'm building some testing procedures for my Kamailio proxy. In order to do that i have a SipTester (Acting as Calling Number) from where i want to originate calls to Kamailio. After Kamailio processes the call, i want it to route it to SipTester again so it can act as Called Number. This should work with only one SipTester in one machine, so i created two SipTester GW's on Kamailio, belonging to different users and GW groups. Also, the two GWs use different Kamailio addresses to communicate with the proxy. However, in this combination, when routing i get this error " ERROR: dialog [dlg_handlers.c:666]: pre_match_parse(): bad request or missing CALLID/TO hdr :-/". If i change the destination or the origin of the INVITE the calls work without a problem. Does this happen because both GW's have the same address? Best Regards

Reading presence state
by Gertjan Wolzak 19 Jul '19

19 Jul '19

Hello Kamailions, I have been able to get the presence configured, subscribers see the status of their subscriptions, this is working fine, for internal, incoming external and external calls. This was solved by enabling use_pubruri_avps in the pua_dialoginfo module. Now I want to be able to route calls based on the presence state. Using the presentity table could be used by doing a query based on the userpart of the ruri, which works fine when the call is still active, but it can take a while for the record to be removed from the presentity table, as that is dependend on the expires value. So when a query is made after a call is finished, a record would still be present in the presentity table till clean_period timer has hit again and the expires value is expired. So I should get the status from memory, but I have not been able to find the information on how to do that. Can someone enlighten me on where to find that information? Rgds, Gertjan

Hey support, Today I ran into this error on my latest 5.2.3 Kamailio box: Jul 18 15:05:28 sjomaintpsg51 /usr/sbin/kamailio[5525]: CRITICAL: tls [tls_init.c:671]: init_tls_h(): installed openssl library version is too different from the library the kamailio tls module was compiled with: installed “OpenSSL 1.1.1 11 Sep 2018” (0x1010100f), compiled “OpenSSL 1.1.0g 2 Nov 2017" (0x1010007f).#012 Please make sure a compatible version is used (tls_force_run in kamailio.cfg will override this check) There's not support for openssl1.1.1 ?

SIP-DTLS support
by Martin Meadows 17 Jul '19

17 Jul '19

Hello, Has there been any movement on the support of SIP-DTLS (datagram-TLS) within Kamailio since: * sr-users:2012-October:075185.html <https://lists.kamailio.org/pipermail/sr-users/2012-October/075185.html> I'm interested to see if Kamailio can proxy 5061/udp to a FreeSWITCH 5060/udp. In general, I have been unable to find any material on implementations of: * draft-jennings-sip-dtls-05.html <https://tools.ietf.org/id/draft-jennings-sip-dtls-05.html> Cheers - Martin
