[asterisk-users] Problem with DTMF dialing

[Ian]

Hi all

I have a small problem here. I asked this question on another asterisk 
mailing list, but nobody seemed to be able to help me there.

We are running

    * Asterisk 1.4.17
    * Libpri 1.4.3
    * Zaptel 1.4.8

on a 1.6 dual core, 2GB ram and a digium TDM800P wildcard, hardware echo 
cancelation and a quad FXO card.

We have 4 analog lines, one of which is a Cellphone line for least cost 
routing.

The  problem I am having is dialing out using DTMF signalling. At the 
moment I am making do with Pulse dialing through the 3 analog lines. I 
can recieve calls on the Cellphone line without any problems, but cant 
dial out through it, as a cellphone cant do pulse dialing. I have run 
"ztmonitor 1 -f gains", where 1 is the zap channel where the cellphone 
is located, while dialing the number 072 031 1294. I then went to 
audacity, on my own pc, and converted the raw file into mp3 format, 
which is available for download at 
http://www.iancoetzee.za.net/tone_dial.mp3. After listening to the 
playback I concluded that the DTMF signals being sent is totally wrong.

The relevant pieces of my configs are below

Your help in this matter will be greatly apreciated.

Regards
Ian
