echo problems.

alanbridgestone · 12 Jun 2008

Hi,

Sorry for not writing in English but...

I am trying to understand what options are available to enable echo suppression in Asterisk in fritz.. At the moment if a client is connecting to Fritz with Asterisk 1.2.19 on board from a remote location I am getting lots of echo.

What options are available to reduce echo for an external caller .., ping time between the 2 networks is 53 ms, so it cannot be latency...

Thanks for sharing your ideas.

Hello Alan,

do the external caller come from PSTN or from Internet?

My callers will all come from ISDN. I have in my capi.conf:

[general]
;rxgain=1.0 ;original ;linear receive gain (1.0 = no change)
;txgain=1.0 ;original ;linear transmit gain (1.0 = no change)
;rxgain=1.5
;txgain=1.5
rxgain=0.8 ;test hall
txgain=0.8 ;test hall

So you can test with r/txgain with that.

But as i understand you have no provider and your friend is calling you via internet directly?
