Jitter, echo, muffled sound common VoIP problems?
 

Compared to our landline phone, I can detect a bit of jitter/warbling of
other party's voice, and when I call to our VoIP phone from an outside
landline, I can hear a bit of echo, plus the other person sounds a bit
muffled.

Are these problems unavoidable with VoIP? We have DSL speeds of 800/140
so I don't think it's related to bandwidth.

My TA is a Sipura 2300.

I'd say 140 was a little marginal, depending on the codec in use and
any other traffic on your link. Also, depending on your route to your
provider and their connectivity, and how they are connected to your
destination, you may well get significant artifacts.

It's kinda like cellphones, the quality is going to hover right on the
edge of "barely acceptable" in order to keep costs down.
