This doesn't sound like the way that sampling errors usually work. They definitely aren't usually so consistent. If it were a sampling error, you may be able to smooth the signal by placing a capacitor in parallel with the unit doing the sampling.
Have you checked the ground on your channel bank? Ground loops generally can pick up buz from power sources in other audio setups. While I would think that a phone setup wouldn't have this sort of problem, it may be worth checking. Does the buz sound like 60hz noise? If so, I'd look for some sort of power-related problem. Good luck. -- Jayson _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
