I am trying to integrate a Nortel Norstar system with an Asterisk service
using a TDM04B card (4 fxo). So far everyting works from Asterisk to Nortel.
The problem is when someone dials from the Nortel PBX to the Asterisk server.
Asterisk answers the call and provides a dialtone (with DISA) but appartently
the DTMF tones are not passed to asterisk and the call cannot proceed.
This only happens when calling from a digital phone on the Nortel. If I
connect an analog phone to the PBX and dial from there the call can go
through. Anyone has experience with this?
