after cultivating google for asterisk echo cancellation i hands up
no matter what value i put on echocancel,echotraining,rxgain and txgain
i do still have echo when doing a conversation with ip phone and pstn phone.
many success stories and different values but it doesnt help me.
but fxs phone and ip phone has no echo(calls will not go to telco). only this pstn phone make me CRAZY.(which go to telco)
its almost two weeks solving this issue with TE110P, Rhino Cbank, Asterisk-1.2.10 and Zaptel-1.2.7.
now i would like to try Latest version of Zaptel and Asterisk but im worried about errors as i can not upgrade thru “update” as installed tar.gz release not the svn.
so what would be the right step in upgrading with tar.gz release.?
im afraid to harm installed files which is working(such as Asterisk and W2k SybasASE connectivity) and will be destroy buy hoping to solve ECHO problem in a way of upgrading into latest version.
what about this transcoding? what is this about?
is it true i can not make linux26 anymore w/ latest version?
