Echo in 7936

Unanswered Question
Dec 20th, 2008


I have CP-7936 (Application Load ID: cmterm_7936.3-3-13-0, Software Version: 3.3(13.00.0008))

installed with ccm 4.1.3(sr5b)

there is echo in the line, when i replace 7936 with any speaker phone it works without echo.

we have PRI(e1) to ccm(mgcp)

I have this problem too.

You may try enabling echo suppressor to reduce the echo during the first two to three seconds of a call, while the echo canceler converges.


gateway(config-voiceport)#echo-cancel ?

coverage Echo Cancel Coverage

enable Echo Cancel Enable
