SIP Registration Issues

Robert Craig
Level 3
Level 3

I am trying to get my CUCME registered with flowroute. Simple task as I have done it with another provider no problem. However, the register packets being received by flowroute are a little interesting.

REGISTER sip:sip.flowroute.com:5060 SIP/2.0.

Via: SIP/2.0/UDP 72.201.112.131:1557;branch=z9hG4bK69539.

From: <sip:08922051@sip.flowroute.com>;tag=83295764-65.

To: <sip:08922051@sip.flowroute.com >.

Date: Sat, 24 Nov 2012 21:31:26 GMT.

Call-ID: 8905D527-35A211E2-811EE65D-4295C626.

User-Agent: Cisco-SIPGateway/IOS-12.x.

Max-Forwards: 70.

Timestamp: 1353792686.

CSeq: 38 REGISTER.

Contact: <sip:08922051@72.201.112.131:1557>.

Expires: 3600.

Supported: path.

Content-Length: 0.

Notice the Contact field has my IP and a different port number on it? Any idea what would be causing it?

Here is my 100% working config from my CME using Flowroute. My CME has the Unity Express AIM-CUE in it as well, and works perfect with Flowroute. Maybe you can pull what you need off of it.

OK, I see a few things I can try. Would the fact that I am also using CME as a SIP registrar cause any problems? I noticed you are using just SCCP phones. I'm trying to use CME as SIP registrar so I can register ATA's.

I do not know. That is my extent of SIP on CME. Now I am configuring (learning) my CUCM 7 with that same CME router (but only used as a SIP to SIP gateway, still with Flowroute). I don't have any registration issues, just other issues, like one way audio.

Actually, between your suggestions and me digging around, I narrowed it down to an access-list on my routers edge interface. I've tried adding statements to allow the traffic in, but when I apply the below list, the registration and any attempts to make a call die. Line 91 should take care of things, but I'm not having any luck.

OK, I managed to get it. I forgot about the RTP ports. Now I'm working on getting the inbound calling to work. Probably something I forgot about somewhere.
