[Freeswitch-users] Cisco phone registration

[Cal Leeming [Simplicity Media Ltd]]

Hello,

The phone shouldn't be sending the IP address, it should be using the
hostname you specified.

I actually did an article, albeit about a NAT issue, on the Cisco 7940
which goes into detail about the SIP packets going to and from the server
[1]. As you can see from this article, the phone is sending the hostname in
the To field.

Therefore, this could either be a dodgy firmware or some config option you
have set wrong.

Can you please give us the following;

* FS SIP trace logs showing the Cisco phone during registration and/or call
state
* Cisco phone config (this can be extracted using the telnet server if you
are not using TFTP)

Hope this helps

Cal
