I had similar problems with a Sangoma card in this configuration. I recently recieved from Sangoma an updated driver that fixed issues with resyncing the clock on the card. You might try getting a hold of Sangoma, David Yat Sin if possible and ask him about it, it may very well be the same problew.

<div bgcolor="#ffffff" text="#000000">
<span>I have AAH2.8 on a dual Xeon system with a
Sangoma A104 and an Adtran Channel Bank.
<br>
<br>
The system has a single PRI connected to port 1 and port 2 has the T1
cable connected to the Channel Bank. Both are configured properly and
work for the inbound/outbound calls and soft-fax reception.
<br>
<br>
I have fax machines connected to FXS ports on the channel bank. The
idea here is to allow faxing out over the PRI from these FXS ports and
for inbound DIDs to go to specific fax machines.
<br>
<br>
I have Asterisk@Home 2.8 setup on this system and I am pretty certain I
have it configured correctly.
<br>
* Each fax machine has it's own Zap extension.
<br>
* The DID routes to the correct fax machine (zap extension).
<br>
* <span style="font-weight: bold;">I can make and receive phone
calls with these fax machines. Meaning, the fax machine has a phone
hand set. I can call out with that handset and receive calls on that
handset.</span>
<br>
<br>
Here's the problem. When I try send or receive faxes it fails telling
me there was a com error.
<br>
<br>
Any ideas?
<br>
<br>
I am at a loss. I have followed the logs. The transmit and receive
work. Once the connection is made it fails indicating "com error".
<br>
<br>
Additionally, I hear the "whistle and chirp" of fax machines
talking to each other. Combined with being able to make and receive
calls over those fax machine hand sets I don't know what the problem is
at this point.
<br>
<br>
Please, if anyone has fax machines setup with a similar situation I
would appreciate knowing how you have it setup.
