[Asterisk-Users] g729 not work with DTMF and AGI

[ht at phonitel.com]

Hello,

I am stuck while attempting to insert DTMF commands from a SIP gateway to an IVR
menu running AGI php scrit.

If I do:

SIP phone --> ulaw --> IVR  then dtmf works fine

If I do:

SIp gateway --> g729 --> IVR then the mneu still works but does not accept DTMF
?

I have tried to set dmtfrelax=yes and dtmfmode=info, also tried dtmfinfo=rfc2833

Still did not work, any clues please?
