Hi,

We are encountering the following DTMF issue,

FreeSwitch adds telephone-event support in INVITE to SBC, SBC replies back without telephone-event support in 200. 

However FreeSwitch still sends out DTMF in RFC 2833 event.

I think FreeSwitch should send out DTMF inband instead of 2833 event, what is the configuration for this?

Many thanks for help,
