Summary:                    DTMF problem on 1.4.17

Hi,

when a call is being passed over from AS5400 via PRI to SIP into asterisk,
dtmf is working in 1.4.11 but not on 1.4.17

Hi Dimas

I was a little hasty in saying my problems with atxfer and automon were
fixed.
I did not test both analog zap and ISDN PRI scenarios until today after
your patch.
Your patch fixed a problem using atxfer and automon on analog PSTN zap
lines BUT did not fix the same problem on a PRI circuit I am using for my
tests.
Outgoing PRI I am able to do an attended transfer or automon perfectly but
on incoming PRI calls I cannot get the atxfer or automon codes to work.
Instead of recording the call on the incoming call when I press my DTMF
*999 the caller hears the DTMF tones and the call is never recorded. Same
applies to atxfer when I dial *2.

I tested this exact scenario on a SIP trunk and it works perfectly
incoming and outgoing so I don't think this is a configuration problem.

I have absolutely no idea what would cause the incoming PRI call to behave
in this way.
Your patch fixed this problem on my analog lines, but not PRI so I suspect
a bug somewhere.
