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.

You don't think the problem is related to my fxotune.conf file being empty
/ full of zeros?
