[Asterisk-Users] Echo cancel: chan_misdn vs bristuff? HFC card vs expensive card?
Hello everyone. I've got a HFC ISDN card that I'm using with chan_misdn and it basically behaves like crap. Echo is waaay worst then echo I get TDM400 card, sound is "choppy" (there other side is allays complaining about sound interruptions) and to top it all it detects fake DTMF's all the time. Is this a chan_misdn problem or is it a card problem? I really need to get this fix and I need to know the way to go. I don't want to throw money at a better card if the card is not the issue but if that's the only solution, I'll need to order the card ASAP!

All ours are running with zaphfc (part of the bristuff package). Might be worth giving that a try. Regards, Chris -- C.M. Bagnall, Director, Minotaur I.T.

Try this settings for echo cancel: in my setup they work wery well (most of the times) [g1] echocancel=256 echotraining=no jitterbuffer=4000 jitterbuffer_upper_threshold=0 -- Best regards, Alessio mailto:afoc@interconnessioni.it
