IMHO this highly depends on the market you and your customers are in.
I.e. in central europe the pots telephony infrastructure has a certain
(high) level of voice and service quality at more or less acceptable rates so
customers will just demand nothing less from VoIP what they are used to get from
pots. For this market latency of more than 200ms are defently too much.
But i agree that there is a bunch of good reasons in other parts of
the world to accept lower quality - mostly price and
availabilty.

Exactly. All connections with Bangladesh, in the absence of any "submarine cable"
connectivity to the internet backbone, go via satellite, which pushes the
latency to somewhere between 650ms and 900ms depending upon the
destination.
All our VoIP calls go via these types
of connectivity, and is of "acceptable" quality. May not be premium
quality, compared to connectivity between other countries / locations, but
this is the best we get, and the delay is easy to get used to.
However, when we have to go via TWO satellite
connections, then the latency goes up to 1300ms - 2000ms which does make
things less acceptable, and we do get complaints from our customers on
that.

If there is no packet loss, even 800 ms
would work. Believe me, it is not as bad as you described it. If the
IP connection is a satellite connection then you would have at
least about 500 and 550 ms delay just between the two
earth stations of the satellite connection.

Also, a terminator may "tweak" his ASR;-)
Besides, who
wants to talk with 800ms ping...
80ms sounds fair, 200ms sounds bad,
800ms is a horror,
unacceptable under any conditions.
