[Freeswitch-users] Force Inband DTMF Reception

Mon Nov 30 15:58:15 UTC 2020

Cześć Adrian,

Tak, to ma sens. Spróbuj może ustawić flagę dtmf_type=none

<action application="set" data="dtmf_type=none"/>

To powinno sprawić, że w SDP ANSWER nie będzie  a=rtpmap:101
telephone-event/8000, tylko nie jestem pewien czy detekcja in-band DTMF
będzie włączona.

pozdrawiam,
Piotr
