Summary:                    DTMF via INFO or RFC2833 via SIP for extensions
processing in Asterisk 1.6 leads to instant channel hangup
Description: 
Basically, calls are received via SIP from one of several providers
(sellvoip, xo, voxbone).  If DTMF is entered via SIP INFO or RFC2833, the
channel instantly reverts to status 'UNKNOWN' and terminates.

I've tried this on several different boxes with the same os and different
hardware and the problem repeats. 

A user entering the information to channel receives an almost instant
hangup upon attempting to enter DTMF.  With debugging on, the server
aknowledges the dtmf as having been entered and then a SIP channel status
change to 'UNKNOWN' followed by an instant hangup which appears more like a
thread stop than anything else.

This problem does not occur on the latest released 1.4 version (not
including svn releases, which wern't checked here).

Of potential consequence is that the system uses realtime/mysql for
extension storage.

I'm not sure what logs are needed for debugging of this dtmf issue or how
to get them.  I can easily get his information though.
