TA904 SIP to PRI to Avaya IP Office

[commorat]

Hello, first time poster and very green to telecom outside of hosted PBX.

We have a customer who has an Avaya IP Office 500 currently connected by a Telco T1/PRI. We are working to replace it with a SIP to PRI connection utilizing the TA904.

Presently we have the SIP trunk connected and the PRI seems to connect when we plug it into the Avaya as we can make outbound calls without issue. However we cannot make any inbound calls, they simply go to fast busy with plenty of debug output. To make things even stranger it randomly worked for 2 inbound calls and we wrote the config and rebooted and it went back to not being able to make Inbound calls again.

Prior to working on the PRI side we set up an FXS port and tested with an Analog phone both inbound and outbound and it worked just fine. The current config is based of the very simplistic example provided by Adtran, our though is the Adtran should leave all call routing, dial plans etc up to the Avaya and simply act as the bridge. I have a feeling it will be something very simple (dial plan/call routing related?) but after many hours/days of trying  a million config changes we are not finding it.

Any help would be greatly appreciated, thanks in advance!
