Hi guys, I have one tricky question regarding SIP peers becoming unreachable.
I was logging the network traffic with Wireshark, and this is what it logged: 10:22:33.319719000 == sent from Asterisk to the phone: OPTIONS sip:mytestph...@172.11.8.30 SIP/2.0 Via: SIP/2.0/UDP 172.32.0.201:5060;branch=z9hG4bK417304ec;rport From: "asterisk" <sip:aster...@172.32.0.201>;tag=as3399559b To: <sip:mytestph...@172.11.8.30> Contact: <sip:aster...@172.32.0.201> Call-ID: 3aacb84e634295120761deac4273d...@172.32.0.201 CSeq: 102 OPTIONS User-Agent: Asterisk PBX Max-Forwards: 70 Date: Thu, 25 Mar 2010 09:22:29 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY Content-Length: 0 10:22:33.349331000 == received from the phone: SIP/2.0 200 OK Via: SIP/2.0/UDP 172.32.0.201:5060;branch=z9hG4bK417304ec;rport From: "asterisk" <sip:aster...@172.32.0.201>;tag=as3399559b To: <sip:mytestph...@172.11.8.30>;tag=6B68E382-AD95AE0B CSeq: 102 OPTIONS Call-ID: 3aacb84e634295120761deac4273d...@172.32.0.201 Contact: <sip:mytestph...@172.11.8.30> Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, INFO, MESSAGE, SUBSCRIBE, NOTIFY, PRACK, UPDATE, REFER User-Agent: PolycomSoundPointIP-SPIP_430-UA/2.2.0.0047 Content-Length: 0 But at the same time, Asterisk reported: Mar 25 10:22:33 NOTICE[1385] chan_sip.c: Peer 'MyTestPhone' is now UNREACHABLE! Last qualify: 28 The phone became REACHABLE 10 seconds later when the first next OPTIONS request was sent from Asterisk. How is it possible that the peer becames UNREACHABLE eventhough Wireshark logged its proper response? This happened on a machine with older Asterisk version (1.2.16) but with all chan_sip.c patches installed. Were there any known problems in 1.2.x version related to this issue? I couldn't find anything remotely similar in the SVN patches...
