Yesterday was very interesting with respect to PSGW. Several co-workers
who are Skype users in the UK called me. I'm in Texas. Those who called
from our corp offices are behind a MS Proxy Server (ISA) and using MS
proxy clients. These calls suffered latency issues that were bad. Not
quote useless, but generally unacceptable.

Later on one of them called me via Skype from his home, with only a
firewall and no proxy server. That call was MUCH better.

This leads me to beleive that perhaps that PSGW software is not the
entire problem.....but it's surely part of it. It's clearly a less than
ideal solution. I suspect that it's better than the VTA-1000, which
would break the Skype call out to a FXS, requiring me to bridge into *
via an FXO. 

I hate FXOs. I've gone to considerable lengths to test FXO devices
(TDM400, X101, SPA-3000, etc) and found none viable long term
solutions. I now call forward my remaining POTS lines to DID provided
by an ITSP. That's been much better than fighting with FXO interfaces
for one or two lines.
