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? -- =========================================Rod Bacon Empowered Communications Ground Floor, 102 York St. South Melbourne Victoria, Australia. 3205 Phone: +613 99401600 Fax: +613 99401650 FWD: 512237 ICQ: 5662270 ==========================================
