Description
Some IVR systems may need DTMF events signalled via SIP INFO messages which can be enabled here.
- Option <off> is the default. The DTMF type is negotiated during the call setup. By default, the phone uses RFC 2833 out-of-band DTMF.
- Option <on> enables sending DTMF codes via SIP INFO messages and in-band or out-of-band DTMF via RTP.
- Option <sip_info_only> enables sending DTMF codes via SIP INFO messages only.
