Valcom V-2904 with MM711

[trilogy8]

Happy New Year-
I've inherited this Valcom door answering system and I'm having difficulty getting this working. I setup a CO/loop start trunk group and am having no luck getting this in service. The door system has an amphenol connector that connects to a 66 block. There is a cross connect on the first 2 pins of the 66 block with the other end to a modulated connector into the MM711. Not sure where the issue is as I didn't think the CO trunk was the issue.

Have you read the manual for the V-2904??

I did, thanks. I got this sorted as it was an inside wiring issue on the riser.
