Summary:                    Severe clicking, popping and talkoff when inbound
call from SIP
Description: 
Under certain conditions, calls to Dahdi channels are full of clicks, pops,
and spurious DTMF digits.  (Usually DTMF-1 for me).

The conditions to reproduce are:
Answer and incoming call from a SIP provider on an analog extension.

Other types of calls are clean and have no problems.  For example:
SIP calls answered on SIP extensions.
SIP extension answering call from analog extension.
SIP extension answering call from SIP, transferred to analog.

basildane:  In your setup, what is the last version of DAHDI that worked
for you?  Also, are IRQ misses increasing in /proc/dahdi/1?

Based on your description, it sounds like problems servicing the interrupt
in time, but if you could tell me a version that worked for you, then I
could look at the differences between the version.  

And please, keep *everything* else the same.  Platform, asterisk version
(you may have to recompile asterisk to move back a dahdi version, kernel
version, etc..
