Hi Nguni,
I've found the solution.
The thing is, that typically SIP signalling uses UDP as a transfer
protocol, but Apple allows persistent connections only with TCP
protocol.
So, here are the steps:
1) Figure out, if your SIP Server supports SIP signalling with TCP (
for example, sip2sip does, ekiga doesn't ).
2) Get rid of UDP connection in pjsua, insert somewhere (
app_config.no_udp = PJ_TRUE; app_config.no_tcp = PJ_FALSE; )
3) If you use outbound proxy, put ";transport=TCP" at the end of url
cfg->cfg.outbound_proxy_cnt = 1;
cfg->cfg.outbound_proxy[0] = pj_str("sip:proxy.sipthor.net;transport=tcp");
4) Add ";transport=TCP" all accounts and register server url, i.e for example:
+a sip:username at sip2sip.info;transport=TCP
sip:sip2sip.info;transport=TCP sip2sip.info username password
Best regards,
