[Asterisk-Users] ISDN, AVM C4, HFC-cards and echo
Hello, I've been using * for quite a while using AVM C4 card and a few Grandstream Budgetone 102 hard phones plus couple of HandyTone 286. Echo is a big problem. I am getting used to it, but some users complain. Anyone has experience w/ regards to echo comparing the AVM C4 with two HFC-cards? Before shelling out time and money, maybe someone else already has done so, and could tell me if it is wortwhile. I only need four B-channels, so two HFC cards should be all I need. Any help, pointers and tips are greatly appreciated. Thanks for your time. rgds pos PS: Current CAPI.CONF settings: [general] nationalprefix=0 internationalprefix=00 rxgain=0.8 txgain=0.8 [interfaces] msn=123456 echosquelsh=1 incomingmsn=* controller=1 softdtmf=0 context=default ;echocancel=yes ;echotail=64 ;deflect=12345678 devices=2 callgroup=1

the hfc-pci cards use the same echo cancelation (in software) that any zaptel device uses.

I have 2 HFC cards. There is no echo. If you use the bri-stuff drivers they use the native zaptel echo cancellers. And I have no echo. None.

RH9 and the drivers from http://capi4linux.thepenguin.de/download/asterisk/ You don't use CAPI or isdn4linux.
