After some research we've found that this may achieve the desired results:

<action application="set" data="rtp_manual_rtp_bugs=FLUSH_JB_ON_DTMF"/>

<action application="set" data="jitterbuffer_msec=60"/>

<action application="set" data="sip_jitter_buffer_during_bridge=true"/>

We will post back with the results after testing.

Hi All,

Is it possible for FreeSWITCH to drop Inband DTMF tones from the RTP\SRTP stream on an inbound call from a carrier so that this isn't audible in the call recording while still retaining DTMF Outofband (RFC2833) in the SIP messages? If not, how could this be achieved?

Thanks,

Shaun
