[Asterisk-Users] Playback problems with T100P

[Eric Einhorn]

Hi,

I'm seeing a problem when calling into my Asterisk server from a T100P
with PRI signalling.  I'm hoping someone has seen this as well, however,
it's a little hard to explain.

When I'm navigating through Asterisk on an inbound call from the PSTN,
I'm getting a random 'noise' during the playback of sound files.  The
best way I can describe this noise, is imagining a windows machine
crashing while it's playing back PCM.  The sound card holds onto the
last few milliseconds of data in it's buffer and plays it in a loop,
creating a (rather painful to the ears) tone.  Another analogy is the
age old "pulling out an Atari cartridge" sound.

The noise lasts for 2 or 3 seconds ceases.  The sound playback continues
afterwards and was never interrupted, or stopped, for the duration of
this noise.  As stated above, this happens at random.

I've tested the line myself with a berd and I have no errors or slips. 
I've ruled that part out.

I'm not sure if the problem is related to the T100P itself, or if it's
caused by the PC hardware, OS, or Asterisk.  I'd like to rule as much
out as I can before calling Digium about the hardware.

Any help is appreciated.

Thank you.
