I just implemented a system using a TE411P hardware echo cancellation card. Per Digium, I setup zaptel.conf, and zapata.conf the same way as I always have. To my surprise calls out to the PSTN had a terrible echo. 1 - 2 second delay, and quite clear. The echo was so bad that I had to remove the hardware echo cancellation module from the card. We are only using the 1st span of this card right now, and we have a tdm400p with 4 fxs modules installed as well.
If anyone has experience with this card, can you tell me if I am missing something. zaptel.conf ================= span=1,1,0,esf,b8zs bchan=1-23 dchan=24 #bchan=25-47 #dchan=48 #bchan=49-71 #dchan=72 #bchan=73-95 #dchan=96 fxoks=97-100 loadzone = us defaultzone=us zapata.conf ================= context=from-pstn switchtype=national pridialplan=national signalling=pri_cpe faxdetect=incoming usecallerid=yes echocancel=yes echocancelwhenbridged=no echotraining=800 rxgain=3.0 txgain=0.0 group=0 channel=>1-23 ;;;;;;[1103] signalling=fxo_ks record_out=Adhoc record_in=Adhoc [EMAIL PROTECTED] echotraining=800 echocancelwhenbridged=no echocancel=yes context=from-internal callprogress=no callerid=device <1103> busydetect=no busycount=7 channel=>98 ;;;;;;[111] signalling=fxo_ks record_out=Adhoc record_in=Adhoc [EMAIL PROTECTED] echotraining=800 echocancelwhenbridged=no echocancel=yes context=from-internal callprogress=no callerid=device <111> busydetect=no busycount=7 channel=>97 Thanks Stagg www.oneringnetworks.com _______________________________________________ --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
