[Asterisk-Users] dtmfmode and IAX protocol

[Michael Giagnocavo]

Actually, there are some phones that will do inband DTMF over IAX2. So if
he's using one of these, he has to make sure his settings are correct. Yes,
the PA168 phones. The correct setting is RFC2833 for IAX (inside these
phones). Otherwise it's inband. The other options they provide just cut the
call.

No.  I'm saying that DTMF digits are always sent out of band when 
using IAX/IAX2(very similar idea to RFC2833 for SIP).  I don't know 
why your DTMF is not working, but it's not a problem with inband DTMF, 
of that I am sure.
