<br>
Echo, as in hearing yourself coming back with a delay?<br>
<br>
Sound flying from the speaker to the microphone at the far end. Dodgy <br>
speaker phone, poor plastic design of the phone, DSP not doing echo <br>
cancellation. Or too much end to end latency - if it is quick enough, <br>
you don't notice. Could be loads of things.<br>
<br>
<br>
<br>
<br>
Quite often with third party USB or bluetooth `speaker phones`<br>
