asterisk users - Apr 2006 - Audio Muting at seemingly random times

Hi everyone,

I've been trying to chase down a bug in Asterisk 1.2. I have 2 
completely different setups which exhibit the same problem, and I'm not 
sure what it is.

For instance, one machine is setup as a voicemail server. If you call 
it, it says "password"..you put it in, and it says, "You have 
On........... ssage. Press 1 for new messages. Press 2 to ch..ge 
folders" etc...

One is a P III 700 with 2 X100P cards, and the other is a PII 450 pure 
SIP using either an X100P as timing, or ztdummy as timing, it exbits the 
same problem. With chan_zap not loading at all on the second box timing 
issues are all over the place.

I also tested on a P4 2.8 Ghz Xeon and again, with no zap channels it's 
completely messed up. I was having trouble with the X100Ps on this 
machine, as it would cause the machine to throw an NMI, and reboot (This 
is an IBM X335).

As a side note, I had NONE of these problems with 1.0.3 - 1.0.7.

Two of the machines are running Debian, one is Fedora Core 4 (PII 450), 
all running 2.6 series kernels.


Thanks for any ideas,
-Matt
