Pawel Kuzak commented on ASTERISK-22789:
----------------------------------------
You marked this issue as fixed, but it is the patch was not implemented in yesterdays 11.8.0 release, is it? I didn't see it in the change log, is there a reason for this?

> After upgrading from Asterisk 10 to Asterisk 11 DTMF recognition does not work as expected. I've attached some SDP examples from test calls.
> # A10_sdp.txt (Callee is Asterisk 10.12.1)
> Caller sends INVITE with telephone-event 99, Callee answers with telephone-event 99, Caller sends RTP event with 99, DTMF recognition works, everything is fine
> # A11_sdp_1.txt (Callee is Asterisk 11.5.1)
> Caller sends INVITE with telephone-event 99, Callee answers with telephone-event 101, Caller sends RTP event with 118 (!), DTMF recognition does not work (here the caller is obviously misbehaving as well)
> # A11_sdp_2.txt (Callee is Asterisk 11.5.1)
> Caller sends INVITE with telephone-event 106, Callee answers with telephone-event 101, Caller sends RTP event with 101, DTMF recognition does not work (note that the payload type 101 in the 200 OK is also assigned for G726-32(!))
> Could you please take a look at it?
