[Asterisk-Users] Nortel ATA not passing dtmf tones to fxo

[Nathan C. Smith]

I fought with this and made the same discovery you did.  

I'm not happy with my solution, but I have SPA-3000s set up in a "hotline"
mode.  when a call comes into them from the Nortel ATA it is automatically
routed to an Aserisk Extension.  I hope somebody else chimes in with an ATA
setting to change or something.

     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?
