WebJan 5, 2024 · Here SBC is taking responsibility for converting the DTMF from in-band to RFC 2833 if we see the signaling negotiation. However, DTMF is not converted in RTP packets by SBC because of which IVR is not recognizing the DTMF digits. The initial INVITE only contained one payload in the SDP, payload 0 (PCMU). This implies that the endpoint does … WebApr 8, 2024 · RFC 2833 is the standard developed for transmitting DTMF digits. The DTMF packets are sent in the RTP packets separately from the RTP audio stream. It can be considered more robust and reliable than Inband DTMF. When given the option between RFC 2833 and Inband DTMF, we suggest using RFC2833. Inband DTMF tmac setup
