Had the exact same issue with the hardware canceller. If I set echocancel=no then the problem goes away. Very weird that the static only happens on our side and we only hear it.

The best way to describe the sound is a background crackle or hiss that just can't be filtered out. Increasing the RX gain just makes the problem worse. SIP to SIP calls are flawless. An acquaintance told me the analog line level is too low, but when plugging a regular phone into the line, the signal is plenty loud enough. I am curious if anyone else had similar issues with the TDM2400 card and if they have resolved it. -- Andrew

The Asterisk box is connected via 20 FXO ports on a TDM2400 with the Hardware echo cancel module. Echo cancel almost works, but the users hear what they describe as a 'crackle' coming back when they talk. I want to tune to echo canceller, but am unsure if any of the options provided have any effect on the hardware module. Do the settings such as echocancel and echotraining in Zapata.conf affect the hardware module? Would I be better removing the hardware module and tuning the software echo canceller? The asterisk box is currently running 1.2.13, with zaptel 1.2. Would you advise upgrading to the newer Zaptel drivers? I don't want to upgrade Asterisk itself just yet. Any help or pointers to documentation regarding the hardware echo
cancel
module would be greatly appreciated, Thanks, Adam Sharples _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
