fair enough.

that I don't agree with, especially not if you do it yourself, but anyway.

Unattended remote systems I run off Compact Flash instead of hard
drives. I can't beat the "no fan" thing though ;-)

I still think it would make sense to run one Asterisk server in Paris
and another in Reno. You don't really need more than that, but of
course it's your choice.

There are no media proxy delays if you use an IAX provider. IAX calls
skip intermediary nodes and go from end to end. That was the point of
my previous message.

If you use H.323 gateway with a SIP provider or vice versa, then you
will also have a media proxy in between because SIP gear cannot
reinvite H.323 gear, there's got to be something in between that
translates. If your entire route is all SIP, then you can go from end
to end. Like wise if youre entire route is all IAX, then you can go
from end to end, too.

Yeah, wine and cheese is better, cheaper and more plentiful in Paris
than in Tokyo and that beats shopping in Akihabara anytime ;-)
