Are you sure it's Sprint's fault? I mean perhaps calling within your own LATA has less delay than calling neighbour LATAs and, combined with the delay that the T100P/TE405P introduces, presents enough delay to perceive echo... IME It's not a telco problem. I also have echo when calling certain numbers, both within and outside of my own LATA (at least I think it is) ... My conclusion is that *s echo cancellation is very hardware-specific, but with echotraining=800 it's good enough for what we use it for. The only problem with echotraining=yes is the 8/10s delay before audio is heard -- sometimes the start of conversations is cut off since our receptionist doesn't have to life a receiver from the cradle to her ear. -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
