Hi, thanks for responding. Just to clairfy it's not always machine 2 as
in my example, just whichever machine was the second to start ekiga.
Which is machine 2 in my example, and I'll continue to use it like that
for future examples.

Alright, when I do echo test 520 from machine 2, the reply call goes to
machine 1. Also, I do not get any remote video when doing echo test 520
from either machine, audio does work though. Secondly, after I do a 520
echo test, if I try a normal 500 echo test afterward, sometimes nothing
works, i don't even hear the operator.

Remote video doesn't seem to work on echo test 520 even with only one
machine. Remote audio does work though.

Usually remote video works with the 500 echo test on both machines
regardless or the order they were started up in.

So, it seems only machine 1 will be callable, and calls to machine 2
will be routed to machine 1. And some calls me, I will not be able to
see their video?

Does that help any?
