AJ: 3640, Televantage and Digital T1

I have a 3640 router with a VWIC-2MFT-T1-DI card connected to an IP PBX (Artisoft Televantage) using an RJ48C cable. I assumed that my cable is now working since the LED in my PBX is already green. The PBX is already configured to route voice to the router when you dial 77. I also configured the router. To test if everything works Iift the handset, got a dialtone from the PBX, then I dial 77 and got a squeaky tone for 1 second and got back the tone from the PBX. Can anyone shed light on this one. Thanks a lot.

Here are the PBX specs:

Framing Type: D4 Superframe

Interface: DSX-1

Supervisory signal: 2- or 4-wire E&M

Wink: Wink and double wink

Line coding/Framing: AMI

Digit signaling: DTMF

DNIS Length: 4 digits

ANI: Yes

My router config:


3640(config)# voice-card 2

3640(config-voice-card)# codec complexity high

3640(config)# controller T1 2/0

I only suspect some signalling issue here. Try immediate start / delay start. It might help you.
