I've been trying to bridge FreeSWITCH with a Toshiba CIX using qsig
over a PRI. I have a Sangoma A102 card installed in a Dell PowerEdge
with CentOS 5.3. The issue I am having is no packets are being
transmitted back to FreeSWITCH. ifconfig w1g1 shows every frame
received as an overrun. I've tried a different server with CentOS 5.3
with the same issue. I have a support ticket in with Sangoma, but was
wondering if anybody had seen this before.

The T1 shows connected so I think I have the Toshiba configured
properly. From what I've read the overrun has to deal with the driver
not reading the data in time so maybe this is a CentOS 5.3 specific
issue. Any recommendations on alternative Linux distros known to work
with the Sangoma A102 card?

Thanks,
Ryan

I know sangoma is working on their new pri stack, maybe it has proper
qsig support. The openzap isdn stack does not right now and I was
under the impression that the libpri support was pretty limited, but
have no direct knowledge there.
