Are these two products compatible? I have the card configured in the gateway with "signal did immediate." In CCM I configure the gateway on a 2821. I set the card up the way I think it should be. I put Num Digits and Expected Digits as 4 as that's what the telco is sending.
Problem is the ports don't register with CCM (although the other FXO ports on the gateway do). When I place a call to a DID number with "debug vpm all" I don't see any signaling.
FXS mode of VIC-4FXS/DID is supported by CCM with MGCP. CCM doesn't support DID mode with MGCP yet. Analog-DID is indeed only supported with H.323/SIP and not with MGCP. But FXS operation on that card should be supported by CCM in MGCP mode.
