Summary:                    DTMF problem on 1.4.17
Description: 
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

OK

I'm having issues with DTMF since my upgrade to 1.4.17 too
I was not having DTMF issues with 1.4.13

Here are the symptoms under 1.4.17
Native attended transfer (*2 in my configuration) no longer prompts for
transfer.
Automon code no longer works (configured as *999)
Express messaging transfer no longer works.

All used to work using a variety of SIP phones including Aastra Polycom
Hitachi Snom.

Now nothing works

I'm attaching three logs:
aragon_dtmfevents.txt
aragon_sip.conf
aragon_features.conf

The files have been edited to remove private information.

The console screams when it receives info from the Snom phone
Snom sends 60 ms DTMF and Asterisk wants minimum 80 ms
Astra and Hitachi both send 160 ms
But the timers (inter-digit DTMF timers I assume) are so finicky that the
atxfer is hardly ever invoked.

All devices are in g711 rfc2833 mode

It is perhaps mentioning that in 1.4.13 the Snom could never properly send
DTMF in SIP INFO mode (I have an open bug report with Snom reporting this
issue but I think this is an Asterisk problem also therefore I only use
rfc2833 on my Snoms also).
