[Freeswitch-users] dtmfmode=auto equivalent in FreeSwitch

Hey all, While I was reading over examples on configuring Asterisk to work with a SIP provider (FreePhoneLine.ca), I was wondering if there is an option just like dtmfmode=auto in FreeSwitch. If not, is there a way to get FreeSwitch to intercept the DTMF tones sent from any client and send them as in-band tone? Thanks for the help in advance!
