[Asterisk-Users] DTMF issues with SIPPhone?

[Jason DiCioccio]

So the way I understand this is with rfc2833, DTMF is sent out of
band.  So does this mean that SIPPhone is interpreting the tones
incorrectly?  Asterisk shouldn't be doing any actual tone detection
with this method, right?

It was the other way around when I first connected us.  Some informal testing just now doesn't show the DTMF tone problem in rfc2833 mode that you're having.
