Echo, as in hearing yourself coming back with a delay?

Sound flying from the speaker to the microphone at the far end. Dodgy 
speaker phone, poor plastic design of the phone, DSP not doing echo 
cancellation.   Or too much end to end latency - if it is quick enough, 
you don't notice.  Could be loads of things.




Quite often with third party USB  or bluetooth `speaker phones`
