It's not an issue other than what others said; junk analog gear and/or people doing dumb things. Another one I found was call center people who don't want to mess up their hair, and wear a headset with the band around the neck, earpiece angled off the back of the earlobe. They turn up the volume to full to be able to hear, and the speaker has a direct line to the microphone hanging 4" away from their face.

I can't say I've experienced it, no.
It was just something a potential customer told me they were concerned with.

So are you saying that you've experienced echo on a fully VoIP call? IP handset to IP handset, without some sort of analog interface other than in the handsets?
I can't recall the last echo complaint we've had.

Well right.
The analog portions of most calls are extremely small anymore (speaker to ear and mouth to microphone).

Well, no call is purely digital, the endpoints are still analog, as is the meatbag behind the handset. I can't imagine any way you can create echo in the digital portions. But a mismatch in impedance on an ATA or similar device would be a common old problem I've faced.

One of the concerns I heard was echo. On a purely digital call, what would be the cause of echo?

I've heard a variety of complaints and concerns over the years about call quality. How are these quality issues introduced? As long as pipes and equipment aren't overloaded, where is a quality issue to come from?
Obviously, the closer you are to the handsets, the less opportunity there is for issues. What else is there to take into account?
