we tried to have the echo test demo… but when we try to talk and hopefully listen back to our voice, nothing. we hear nothing… and it was a failure then… can somebody help? what is the problem? is it in the asterisk? or is it in the hardware? please help…
It may as well be expectation. Why do you suppose it’s a failure? Yes you are more than likely to have heard something. Just can’t perceive it. See voip-info.org/wiki/view/Causes+of+Echo for an explanation.
