SIP/2.0 400 Bad Request No matching peer

Asterisk Asterisk SIP
1

Does anyone know what might be going wrong here?

This is the only phone that is doing this. It is a Cisco 7970 and it is showing a 400 Bad Request when I show debugging in SIP. It looks like it is trying to do a PUBLISH and then Asterisk is saying that it has no matching peer.

Here are the details:

Thanks in advance.

Do you have a peer named 00131a592255?

3

Definitely one of my thoughts. I don’t have a peer named that, but I don’t know where it’s getting that name from.

4

It looks like a MAC address.

5

I just looked at it and it is indeed the MAC address of the phone having the issue. Why would it try using that as the peername though?

6

It’s probably thinking it is connected to CCM where it is expected that the phone publishes information to the server based on MAC address. As chan_sip does not allow publishing even if it did match it would get rejected.

7

I understand. It’s interesting because that particular model is the only one that does that. The 7961,62 and the 7975 I have don’t do that. But anyway that’s not really an Asterisk problem.

Things continue to operate fine, I just didn’t want my Asterisk server to constantly be trying to do something over and over it doesn’t really want to do.
