Hi Jan, I'm trying to connect linphone to my kamailio ims. Only register request is sent from Linphone and no acknowledgement is received. I'm attaching you my linphonerc file. Please advise if any correction is required in the configuration.

Hi, I am a newbie to sipclient Linphone. I know this issue is not related with kamailio.Yet If anybody have tried it before , kindly provide me with some links or procedures to be followed for call registration and connectivity with kamailio since in my case, request is going but response is not coming back resulting in timeout issue.

This happens only in linphone.If i do the samething in PJSIP/zoiper, call registration and call establishment happens perfectly fine.

Kindly help.

Thanks, Pavithra

Hi Jan, I have also tried as u suggested with reg_proxy only with sip server name, could not obtain any positive changes. I have also attached the debug logs, please have a look and suggest for any changes. Thanks in advance.

Hi Jan, Sorry for the delayed response. I guess the issue is because of UDP transport, which my kamailio is not accepting. Because the same scenario is reproduced when I change my pjsip configurations to udp instead of tcp. But linphone gives me the following error if I tried to connect using tcp.

*ortp-error-wrong state: create transport layer firstortp-error-wrong state: create transport layer firstortp-error-eXosip: missing via header* Am I missing something really important? Please let me know. Thanks in advance.

Hi,

I'm answering as the author of libosip & libeXosip ;)

Linphone, in your case is based on eXosip. Linphone removed eXosip2 years ago and thus, you use a very old linphone and very old eXosip2 version..

Anyway, whatever versions of eXosip2, it needs to be used that way:

ctx = eXosip_malloc http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#ga8ebd76492c77690fee6f3781abcfd692 (); if (ctx==NULL) return -1; i=eXosip_init http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#gaf0d9eb7def600c00166c06185b7f6fb3 (ctx); if (i!=0) return -1;

i = eXosip_listen_addr http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#ga07d7c2b336f7145fe55a8d481fccc44a (ctx, IPPROTO_UDP, NULL, port, AF_INET, 0); if (i!=0) { eXosip_quit http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#gacfd12dbf24afb5182dd9b7269ea41cb0 (ctx); fprintf (stderr, "could not initialize transport layer\n"); return -1; }

If eXosip_listen_addr http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#ga07d7c2b336f7145fe55a8d481fccc44a is failing nothing can be done with eXosip2, and " create transport layer first" logs will happen for some API which can't be used in that state.

http://www.antisip.com/doc/exosip2/group__howto__initialize.html

If the socket can't be created, the above API will fail. So a usual scenario is to have the port already used.

A simple way is to choose another port when this is happening and I guess this old version of linphone wasn't doing that:

i = eXosip_listen_addr http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#ga07d7c2b336f7145fe55a8d481fccc44a (ctx, IPPROTO_UDP, NULL, port, AF_INET, 0); if (i!=0) i = eXosip_listen_addr http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#ga07d7c2b336f7145fe55a8d481fccc44a (ctx, IPPROTO_UDP, NULL, 0, AF_INET, 0); if (i!=0) { eXosip_quit http://www.antisip.com/doc/exosip2/group__eXosip2__conf.html#gacfd12dbf24afb5182dd9b7269ea41cb0 (ctx); fprintf (stderr, "could not initialize transport layer\n"); return -1; }

Maybe your user doesn’t have rights for that? Have you tried running it as root to see if you get the same error

Hi Aymeric, Thanks for your reply. Yes, as you said I get the below warning when I start Linphone. But the port is actually not used by any other application. And one more thing is, I see this error only in case of enabling TCP transport and not in UDP. So does that mean, linphone works only with UDP transport? *Warning: Could not start tcp transport on port 4060, maybe this port is already used.*
