[Asterisk-Users] Scratchy audio on Bridged PRI Calls

[Rod Bacon]

I have a number of servers with TE405P cards. The servers are DELL 1850's (which I _NOW_ see are listed on the digium "not recommended page" because
of the ethernet interface).

The problem I have is only during bridged calls.

If I place a call into a service hosted on the box, or out to a VOIP phone, audio is crystal clear. If place a call "through" the box (a bridged PSTN
call)  the calling party hears some form of distortion when the other party speaks. Almost like a buzzing/crackling sound.

I have been right through the interrupt sharing issue (disabled ACPI, APIC, Hyperthreading, Frame Buffer, etc. etc.) and am getting good results in
zttest. I see NO IRQ misses or any other errors at the console.

Does anyone have any other ideas?
