[asterisk-users] They ignore my DTMF!

[Joanna Liza Mariazeta]

Hi Pierre,

Just a thought..check your dtmfmode in your SIP client configuration, if
your using inband but your codec is not ulaw or alaw the DTMF tones will be
misrepresented and thus will not be recognised due to the audio compression,
on the other hand if your phones are rfc2833 and asterisk is set to inband
you wont hear anything.

Hope that helps.

Best Regards,
Joanna
