[VoiceOps] Call Quality

[Mike Hammett]

God, I hope customers don't hold their carriers responsible for inappropriate use of speakerphones. 




Yes, I'm sure the complaints received for the above are non-null. That's how much faith I have in customers.

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`
