[Freeswitch-users] DTMF negotiation

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,
/Kaiduan
