Many thanx in advance
Hi,
Echo is one of the most common problems in packet switched networks. It can have a variety of causes.
Always keep this in mind:
If you are on extension “A”, calling to “B” and you hear your own voice,
Then the problem is at the “B” end ! After all, it is the “B” extension that reflects your voice back on the line.
Check whether you can enable echo suppression on your “B” end extension.
Happy hunting …unting…ing…
