[Freeswitch-users] Force Inband DTMF Reception

[Piotr Gregor]

Cześć Adrian,

Tryb w którym FS będzie używał DTMF zależy od trybu który jest oferowany w
SDP INVITE.
Zazwyczaj klient jest konfigurowalny, np. w Bria: Preferences -> Calls ->
DTMF: Send in-band.
Tak więc upewnij się, że to nie klient żąda RFC 2833.

pozdrawiam serdecznie,
Piotr
