[Freeswitch-users] DTMF detection in the core & spandsp

[Mi Ke]

It appears that we cannot use carrier's RFC2833 sequence as it's missing up to 50% of digits sent to them by the original caller. And this is not happening on the same system with 2 other carriers.

 Peter and Michael, thank you very much for your help and explanations.

 WBR / Mike

So in order to use just spandsp I need either to disable RFC2833 detection at my side or to ask originating party to disable sending us RFC2833 and just send us audio intact - have I got your point ? That's kinda sorta what he's saying. A better way of saying it is this: if your carrier sends you RFC2833 DTMFs then you don't even need to turn on dtmf detect stuff. Unless there is a compelling reason to go in-band I'd say just use RFC2833 and be done with it.
