Thanks, Avi. I just tried that, but it seemed to have no effect. This is what I had in the dialplan: <action application="start_dtmf" /> <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"/> <action application="bridge" data="user/${dialed_extension}@${domain_name}"/> I then used Zoiper, configured with DTMF set to inband, to call a Snom handset. Any DTMF sent from Zoiper, on the aleg, was detected as SWITCH_DTMF_INBAND_AUDIO, but the tones are still being clearly heard on the bleg at the Snom handset. Is there something else I need to set (or not set)? Andy On 12/07/16 16:00, Avi Marcus wrote:

Does anyone know how to filter inband DTMF, on a bridged call, such that inband DTMF from one leg is not passed to the other leg?
E.g. replace the DTMF with silence or, possibly, a masking tone?
Many thanks
