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

Snom is only partially buggy in SIP INFO mode:
Snom allows a softkey to be programmed as a DTMF event
So I program my automon code *999 to a key in SIP INFO mode and the
automon is not activated.
By dialing the digits *999 manually I can trigger Asterisk to record the
call.
The snomSIPinfoDTMFfail.txt captures both events.

Another test of Snom V7 7.1.30 firmware provided bizarre DTMF results
using rfc2833 regardless of whether softkey or manually pressing DTMF
keys.

All of these tests were done over a PRI trunk.

So I ran a slightly different test using rfc2833 invoking DTMF from local
extension to local extension and the DTMF was properly invoked.

I'm beginning to believe there is a problem with DTMF over zaptel (at
least on my PRI span). Possibly only with Snom phones???

Span is a Digium TE412P connected to a Nortel BCM.

Configured in my lab and remote access can be arranged.
