Hello Everybody! My server is attempting to connect to a SIP device, but is not succeeding to. I checked the actual packets traveling back and forth with ngrep and I noticed some odd packets coming in.
Here is the outgoing INVITE packet sent to the SIP device: # U asteriskserver:5060 -> sipdevice:15244 INVITE sip:3...@sipdevice:15244 SIP/2.0..Via: SIP/2.0/UDP asteriskserver:5060;branch=z9hG4bK7cb4b7a7;rport..From: "m" <sip:6571...@asteriskserver>;tag=as6e2a8098..To: <sip:3...@sipdevice:15244>..Contact: <sip:6571...@asteriskserver>..Call-ID: 5f79e4897d6ab4793ed0724935192...@asteriskserver..cseq: 102 INVITE..User-Agent: Asterisk PBX..Max-Forwards: 70..Date: Sun, 01 Feb 2009 10:27:14 GMT..Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY..Supported: replaces..Content-Type: application/sdp..Content-Length: 269....v=0..o=root 17661 17661 IN IP4 asteriskserver..s=session..c=IN IP4 asteriskserver..t=0 0..m=audio 11272 R TP/AVP 18 101..a=rtpmap:18 G729/8000..a=fmtp:18 annexb=no..a=rtpmap:101 telephone-event/8000..a=fmtp:101 0-16..a=silenceSupp:off - - - -..a=ptime:20..a=sendrecv.. Unfortunately, there is no response from the sip device. However, this packet shows up with ngrep from the sipdevice: # I sipdevice -> asteriskserver 3:1 ....E.......5...................INVITE sip:6571...@sipdevice SIP/2.0..Via: SIP/2.0/UDP asteriskserver:5060;branch=z9hG4bK 0102c4c0;rport..From: "m" <sip:6571...@asteriskserver>;tag=as47be5d18..To: <sip:3...@216.235.152.22>..Contact: <sip:6571...@asteriskserver>..Call-ID: 16e6211c310d36905520dcb625f86...@asteriskserver..cseq: 102 INVITE..User-Agent: Asterisk PBX..Max -Forwards: 70..Date: Sun, 01 Feb 2009 10:36:51 GMT..Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY..Supported: replaces..Content-Type: a Apparently, the device is getting a packet, but its response is not being sent back properly. The sipdevice is sending a packet, but instead of being sent to port 5060, it is sent an odd port of 3:1. Moreover, there are some phantom characters that show up the beginning of the return packet (....E.......5...................I). Any help would be great!
