We are trying to integrate Nortel CICS phone systems with the Multitech MVP410 gateways. The problem we have is with the Nortel.


When making a call to an extension, or in this case ATA (Analog Telephone Adaptor) using station ports, the DTMF tones following the initial station code are either too short for the MVPxxx to see or suppressed inside the Nortel.


A work around is to enter the Long Tones feature code (Feature 808) which then passes the DTMF tones after an intercom call is placed.
