Easy. Get better endpoints. In a pure-voip loop you have echo due to
acoustic coupling from the earpiece to the mic, or the speaker to
the mic in
a speakerphone. Easy way to tell: in a call with bad echo, have the
other
side mute. If your echo goes away, you've got your culprit.
Also note that if your transmit level is too high or they have the
volume up
too loud on their end it could push the audio coupling over what the
design
specifications were.
We're having some issues with a Budgetone, especially in speaker
phone mode causing echo. I think I read the specs have a feature
line item of "Echo cancellation (pending)", lol.
No way to fix this other than buying new phone(s)?
