DTMF Conguration Properties
• DTMF using SIP INFO (RFC 2976) – The DTMF attributes are sent in a Session Initiation Protocol (SIP) message according
to the RFC 2976 standard.
• DTMF using RTP INFO (RFC 2833) – A DTMF event is sent with the Real-time Transport Protocol (RTP) stream according
to the RFC 2833 standard.
Both SIP INFO and RTP are out-of-band methods, meaning that the DTMF packet is sent in a dedicated channel, separated from
the one used for the voice call. Digital out-of-band packets, as opposed to analog in-band tone signals, cannot be heard by the
callers and are resistant to falsing.
