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

[ht at phonitel.com]

Hello,

I have an AGI script that runs a menu at two levels of a tree.

If I call the extension from a voip phone with g711, the menu works fine and
accepts DTMF no probs.

Then, when I Call from a DID, it sends call using SIP and g729 to¨* box.

The IVR also starts running, but no DTMF is deteced.

I have tried various configs (combinations of dtmfmode=info, dtmfmode=rfc2833
and dtmfrelax=yes, dtmfrelax=no) with no success. Any hint?

sip.conf

[SS_SIP]
type=peer
host=XXX.XX.XXX.XX
dtmfrelax=no
;dtmfmode=rfc2833
dtmfmode=info
context=outbound
disallow=all
allow=g723.1
allow=g729
