[asterisk-users] Playing DTMF tones down a channel

[Lees, James (UK)]

Hello,

I am trying to play DTMF tones across a phone line to control the
voicemail application. The voicemail app is not however detecting the
tones. Does anyone have any suggestion of what I can change to help
things along?

I have tested playing the tones between two standard clients and the
tones can be heard on the receiving client so the issue must be
regarding the detection of the tone.
Many thanks

J
