Failed Outbound calls though OBi110

The PBX, OBi, and admin computers are all connected through a (dumb) netgear
switch on my desk, which connects to a gateway router at 10.10.0.1 ( in fact
almost the entire university is on that VLAN ( the 10.10. network).
So, addresses would have to be unique…

As I posted earlier, the network manager also was puzzled by the extra address,
but he didn’t have time to pursue it…we tried various experiments to figure it out…
all inconclusive.

Anyway, for now at least, I have something to work with in this self-tutorial in
IP Telephony…

Many many thanks for your help - I probably could never have figured this out
alone!
