T904 PBX out to SIP and SIP in to PBX

[jeremycw123]

I'm a bit new to the Adtran T904 but I have been scouring for days trying to figure out what I'm not understanding. I have an Adtran T904, I have an isdn pri connected to a PBX. I have a SIP trunk to a SIP provider. When I place calls out from the PBX, they go to the SIP trunk and that works just fine. When I call in to the number I have from my SIP provider, I want it to pass it to the pri, and the PBX then sends to the correct extension. However, when I call in, I get SIP 404 not found, and it doesn't seem to pass it to the pri. The config is very basic, I'm just trying to get it up and running. I've attached my vetted config. If anyone can point me in the right direction, I'd be much obliged.

Jeremy- 

If you are getting a 404 error, then there is something the SIP provider or TA900 is not okay with. 

Have you ran the following debug to see why you are getting the error?

debug sip stack messages

debug voice switchboard

Thank you. I did, I should have included the debug logs in the original post. I've attached it. The one thing I'm not sure about is that calls outbound to the SIP provider go to the .50 address, while inbound calls come from .60. Would I need to create another SIP trunk for the .60 incoming?

Well, that may have been it, I added sip-server secondary with the .60 address and now the incoming call is knocking on the PBX's door. So now I just need to debug the PBX side. Rubber duck debugging at it's finest.

Well, now there's no called party number being sent to the PBX, so maybe something still on the Adtran side

[jeremycw123]

Actually, it's sending all 10 digits to the PBX when the PBX only expects up to 8 digits max.

PBX looking for a subscriber number. I added: match dnis 3338880000 substitute 0000 to the isdn trunk. It works now. Thank you.

Excellent! Glad you have been able to get it working.
