Hi There, We are using 2 x AVM Fritz BRI cards with mISDN. The phones are Linksystem SPA922's and we are getting a little echo on the lines.. from what i unserstand, these are passive cards and do not have any onboard echo cancellation, but im wondering if there is anything that can be done software/config wise to help with this?
I did find this (http://www.misdn.org/index.php/FAQ): 4) You set another value for tx-gain, "-1" for example to prevent echoes. Please set the tx-gain back to "0" for those calls as in 3) ("vt0"). Can anyone comment on this please?
