asterisk users - Aug 2003 - DTMF onto the reall world

Hello All,

 

I was originally having problems just getting DTM from the SIP phone
over to asterisk for the voice mail app. But through settings in the SIP
client got that working. I am know at the stage know though that
asterisk doesn't appear to be passing DTMF over to the real world, I am
using ISDN 4 Linux with an ISDN2e. 

 

What settings in Asterisk are responsible for this?

 

Thanks

 

Nick
