Hi, I'm a newbie to pjsip. I'm testing the pjsua application on Ti Davinci. The OS is arm linux with kernel 2.6.10. The network interface is an CDMA2000 EVDO through ppp dial. I can ping sip.antisip.com with this interface. Pjsua failed to register the account with the following output : .. 00:28:27.960 pjsua_core.c TX 467 bytes Request msg REGISTER/cseq=22488 (tdta0x124798) to UDP 91.121.81.212:5060: REGISTER sip:sip.antisip.com SIP/2.0 Via: SIP/2.0/UDP 117.71.153.120:5020;rport;branch=z9hG4bKPj921ebbbe-46c5-4c66-8f57-53e693d605 a5 Max-Forwards: 70 From: <sip:bvtest1@xxxxxxxxxxxxxxx>;tag=f4d7cbdf-6267-4936-8d49-f1601b60ff17 To: <sip:bvtest1 at sip.antisip.com> Call-ID: e99a52f3-107e-4fee-87f7-a0d59443a30e CSeq: 22488 REGISTER User-Agent: PJSUA v1.4-trunk/arm-unknown-linux-gnu Contact: <sip:bvtest1 at 124.113.128.65:5020> Expires: 300 Content-Length: 0 00:28:31.960 pjsua_core.c TX 467 bytes Request msg REGISTER/cseq=22488 (tdta0x124798) to UDP 91.121.81.212:5060: REGISTER sip:sip.antisip.com SIP/2.0 Via: SIP/2.0/UDP 117.71.153.120:5020;rport;branch=z9hG4bKPj921ebbbe-46c5-4c66-8f57-53e693d605 a5 Max-Forwards: 70 From: <sip:bvtest1@xxxxxxxxxxxxxxx>;tag=f4d7cbdf-6267-4936-8d49-f1601b60ff17 To: <sip:bvtest1 at sip.antisip.com> Call-ID: e99a52f3-107e-4fee-87f7-a0d59443a30e CSeq: 22488 REGISTER User-Agent: PJSUA v1.4-trunk/arm-unknown-linux-gnu Contact: <sip:bvtest1 at 124.113.128.65:5020> Expires: 300 Content-Length: 0 00:28:32.460 tsx0x125804 Timeout timer event 00:28:32.460 tsx0x125804 State changed from Calling to Terminated, event=TIMER 00:28:32.460 pjsua_acc.c SIP registration failed, status=408 (Request Timeout) 00:28:32.470 tsx0x125804 Timeout timer event 00:28:32.470 tsx0x125804 State changed from Terminated to Destroyed, event=TIMER 00:28:32.470 tdta0x124798 Destroying txdata Request msg REGISTER/cseq=22488 (tdta0x124798) 00:28:32.471 tsx0x125804 Transaction destroyed! Why will SIP registration fail? How can I use TCP to send REGISTER? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
