[Asterisk-Users] Echo heard by person receiving call

[Richard Scobie]

Thanks Mark,

I have been scratching my head for the last couple of days, wondering 
why I could not get echo can. to work, because page 51 of the draft 
manual says:

echocancel: Disable or enable echo cancellation. In almost every 
configuration it is recommended that this be left on (or left unstated, 
as the default is always on.)

I had thus not added the echocancel= in zapata.conf

Once I did, mec3 is doing a great job.

Regards,

Richard
