You haven't told us what hardware (platform) you're on, nor have you told us if your FXO ports are in whatever mode they need to be in for UK impedances (I think they default to FCC or North American). For echo on my PRI I could not get rid of it until I recompiled the zaptel and wct4xxp drivers with MMX support enabled and with the instructions reordered and used for the pentium 4 processor (which I'm using, Xeon 2.6 to be exact). After that, the echo magically disappeared. I haven't reverted back to my original (non-processor-optimized, non-MMX-enabled) drivers to see if it comes back, but that's all that's changed and it's in production so I am hesitant to screw around with it any more. -A. _______________________________________________ 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
