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?
