Asterisk, MGCP, and InterTel Axxess

I’m attempting to link my InterTel Axxess system to Asterisk via MGCP. I’m hoping someone out there has had some experience with this setup, or something similar.

I have MGCP endpoints configured in the InterTel system, and it’s attempting to talk with my Asterisk server. However, Asterisk keeps complaining about it:

[code]asterisk*CLI> mgcp show endpoints
Gateway ‘intertel’ at x.x.x.x (Static)
– 'line/3@intertel in ‘outbound’ is idle
– 'line/2@intertel in ‘outbound’ is idle
– 'line/1@intertel in ‘outbound’ is idle
– 'line/0@intertel in ‘outbound’ is idle

WARNING[16492]: chan_mgcp.c:3255 handle_request: Unknown verb ‘AUEP’ received from x.x.x.x[/code]

I did a snoop on the network traffic and I see this (x.x.x.x is the InterTel, y.y.y.y is the Asterisk server):

171 1441.282856 x.x.x.x -> y.y.y.y MGCP AUEP 1078 line/0@intertel MGCP 1.0 172 1441.283753 x.x.x.x -> y.y.y.y MGCP 510 1078 Unknown verb

So, it looks like the InterTel is trying to ask Asterisk for an audit, but Asterisk isn’t expecting it. Does anyone have any suggestions?

Reckon I should have included the following in the original post:

Running Asterisk 1.2.6 on a Fedora Core 4 box (i386).

…and for any InterTel-knowledgable among you: The InterTel system is running software version 9.0 with the most recent patch as of this post.
