I am sending SIP registration and I get 200 OK messages back however something is not right . In /var/log/asterisk/messages I am getting : [Jul 15 16:40:42] NOTICE[2875] chan_sip.c: -- Registration for '5492 at 10.164.112.3' timed out, trying again (Attempt #33) Its not correctly registering. - however I am getting 200 OK back. and I am not able to make a call. What is not happening here? I am getting 200 OK back why does asterisk think its not registered and not make the call? What do I need to change? thanks, jerry [sip.conf] register => 5492 at 10.164.112.3/5492 [5492] type=friend authuser=5492 username=5492 fromuser=5492 dtmfmode=rfc2833 disallow=all allow=ulaw allow=alaw context=smvoice-incoming host=10.164.112.3 canreinvite=yes qualify=no ??REGISTER sip:10.164.112.3 SIP/2.0^M Via: SIP/2.0/UDP 10.164.17.3:5060;branch=z9hG4bK037755ad;rport^M From: <sip:5492 at 10.164.112.3>;tag=as41a57d56^M To: <sip:5492 at 10.164.112.3>^M Call-ID: 47c262f877f461e93210812d1e8cc8d0 at 10.164.17.3^M CSeq: 104 REGISTER^M User-Agent: Asterisk PBX^M Max-Forwards: 70^M Expires: 360^M Contact: <sip:5492 at 10.164.17.3>^M Event: registration^M Content-Length: 0^M SIP/2.0 200 OK^M Via: SIP/2.0/UDP 10.164.17.3:5060;branch=z9hG4bK037755ad;rport^M From: <sip:5492 at 10.164.112.3>;tag=as41a57d56^M To: <sip:5492 at 10.164.112.3>;tag=1270221403^M Call-ID: 47c262f877f461e93210812d1e8cc8d0 at 10.164.17.3^M CSeq: 104 REGISTER^M Contact: <sip:5492 at 10.164.17.3>^M expires: 360^M Content-Length: 0^M
