The round trip time to a well connected (read: 0% packet loss) server
in Israel from an Israeli ISP, where Israel here is defined as
"connected to the IIX", is under 50ms.</div>

On a 150kbit upload ADSL upload of a 1500 bytes packet takes about
85ms. To send out the VoIP packet would take another 85ms (on condition
that you have a really good QoS). This causes latency of 85-170ms with
jitter 85ms. The VoIP speech (SIP protocol) has a lot of skips and is
unacceptable.<br>

ahem... accept in real life VoIP packets are rarely larger then 250
bytes (most of the time then are not over 100 byes) and that the SIP
protocol doesn't actually carry any media (read: voice) information -
that is left for RTP.<br>
<br>
More to the point - VoIP , in general works great. In the (very
distant) past been on the technical team of a VoIP start up and trust
me - VoIP works great on ADSL lines.<br>

That I agree completely - that fact that VoIP works doesn't means that
018 do... :-)<br>

Everyone has nightmares. Even monsters from under the
