[Freeswitch-users] group_confirm with inband DTMF detection

Hi all,

I want to enable FS to accept inband DTMF with the group confirmation. I
tried to do start_dtmf action on the call legs, however that action is only
executed after the confirmation, so the actual confirmation requires an out
of band DTMF.

Here is one example that demonstrates the issue:

{group_confirm_file=/tmp/ivr-group_confirm.wav,group_confirm_key=1,call_timeout=60}sofia/sipinterface/number at provider

Any ideas? Ideally I want to enable system-wide inband DTMF detection in a
safe way at some CPU cost.
