[asterisk-users] Cisco FXS Issue...

[William Stillwell (Ki4swy)]

Im sure this has been thrown around this list 1,000 times, and Im sure its been around the net too.. But I have done everything, and cannot seem to get inward calls to be processed on my asterisk box..

First, Let me tell you what works:

1) Softphones (ZoIPer using IAX2 Protocol) Can make calls behind a Natted Firewall to the FXS Port, and it rings, and calls work full duplex.

2) Soyo IP Phone (Loaded with IAX2 Firmware) Can make calls on the same subnet as the asterisk server, and can talk full duplex to the FXS Port.

3) I can call other FXS Ports on the same Switch.

The cisco box does register.

Dialing anything on the fxs port results in "Fast Busy" with no warnings/errors showing up console.
