Subject: Re: [Freeswitch-users] How to drop Inband DTMF tones while retaining Outofband DTMF tones?

Try setting rtp_manual_rtp_bugs=FLUSH_JB_ON_DTMF and enable the jitterbuffer by setting the channel variable jitterbuffer_msec=60.

This is the solution to https://freeswitch.org/jira/browse/FS-4905

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
