Thanks for the helps Stephen. I was running non standard gains but setting regain and txgain to zero (then reloading chan_zap.so) does not help. I still get the broken audio, in fact sometimes I don't get any audio at all. In testing the server just froze a number of times and had to be rebooted via the power switch.
I am using the latest Zaptel 1.2.16 files and the latest fxotune from the 1.4 release and I still see this issue. Very interested to get this working but without the HPEC my server is rock solid (only have to reboot it when I install kernel updates). I don't believe it is my system but am happy to do any testing others may suggest.

I have observed very similar behaviour in an HPEC installation. Some observations: the clipping happens if receive gain is cranked up. If I set the gain to defaults, the clipping goes away, but then I have the problem of users complaining that the remote caller is too quiet. Another recommendation -- whether or not you are using Zaptel 1.2.x or 1.4.x, you should always the fxotune from 1.4.x. A question - do the people who are experiencing this problem have non-default gain settings, either in zapata.conf or in the telephone sets? -Stephen- _______________________________________________ --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
