[cisco-voip] Nortel 81c <-> ADTran 908e <-> SIP CUBE <-> AT&T SIP trunk

[Austin Williams]

 Hey All,

We are attempting to lab out a solution to remove all of the PRIs set up at
our locations. Many of these locations have older phone systems that do not
directly support SIP. (for example: Nortel 81c) Our solution is to create a
NI-2 trunk from the older phone systems to an ADTran and then a SIP
connection from the ADTran to our SIP Cubes and then to the Carrier via
their SIP trunk.

Our Current issue is that after creating the NI-2 trunk and getting the
D-Channel to establish we get the following warning: 2019.06.19 11:37:06
TM.T02 0 WARNING Trunk has no b-channels

When attempting a call out from the Nortel to the ADTran and to the SIP
CUBES we get: 11:40:09.425 TM.T02 0 Cannot accept calls - trunk being
configured or trunk full

When attempting a call in from the carrier through the SIP CUBES to the
ADTran we get: 11:42:07.676 TA.T02 Deliver event rejected, trunk out of
service

I am attaching our "Sanitized" config at the bottom of this email and would
appreciate any thoughts anyone has. If anyone wants to see any debugs let
me know as well.
