Hello I recently have got my setup up and running. I am using 2 x100p cards in a Dell 400SC. I get static (inbound and outbound) within the first 20 seconds on one card, but on the other card it is crystal clear all the time. They both have their own irq and I have tried to remedy the problem by doing a hdparm found in the wiki, but still nothing. I've tried rxgain and txgain, but that just seems to increase and descreas the static volume. The other problem I have is that I get a bad echo on both cards when using them. I can hear myself constantly. Here is my zapata.conf: signalling=fxs_ks echocancel=yes echocancelwhenbridged=yes echotraining=400 callerid=asreceived group=1 context=pots1-inbound channel => 1 signalling=fxs_ks echocancel=yes echocancelwhenbridged=yes echotraining=400 callerid=asreceived group=1 context=pots2-inbound channel => 2 Any help is greatly appreciated! TIA. -Bobby -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20050204/59c6f570/attachment.htm
