[Asterisk-Users] DTMF Simultaneous Inband and RFC2833 performed by Asterisk => Duplicate tones
Max Glucksmann wrote:> - RFC2833 standard configured on both end-points.If this is the case, but the end sending DTMF _also_ puts it inband, then it is broken. This is an either/or setting; it's either inband or out of band, but not both. Asterisk sometimes listens for inband DTMF even when RFC2833 has been specified because the SDP tells us what the peer wants to _RECEIVE_, not necessarily what it will send. There are devices out there that will tell us they want RFC2833 but send only inband... many devices are just broken and/or inconsistent.
Apparently Analagous Threads
- DTMF Tones in RTP Payload as Well as in Events = Duplicate Tones
- DTMF Simultaneous Inband and RFC2833 performedby Asterisk => Duplicate tones
- Can I make asterisk do inband and rfc2833 at the same time?
- "Inband DTMF is not supported on codec G.711 u-law. Use RFC2833"
- DTMF issues/redial tones with rfc2833
