Hi all,

I have an issue with receiving inband DTMF tones on incoming call to IVR. I've set both internal and external SIP profile to dtmf-type: inband;
NameValueEnabled
dtmf-typeinbandTRUE

fs_cli shows this debug message:
[DEBUG] switch_core_media.c:5980 No 2833 in SDP. Disable 2833 dtmf and switch to INFO

Provider can only send inband dtmf.

On outgoing calls DTMF works as expected.

Any help would be appreciated.
