I have been looking into peer to peer - where one "dials" the IP
rather than going through a provider. I got the idea from the recent
thread on BT Home Hubs.

I decided to do a bit of local testing myself as I have a Zyxel ATA
with two lines. So I set the phone book up with two entries each
pointing to the other line via the external address (I have fixed IPs)
- You have to use the phone book as you can't "dial" an IP.

If I call either phone from the other using their "land line numbers",
ie it goes to the provider and back again, the other phone rings. But
if I use the speed dial IP entry I just get silence. If I use the
speed dial entry to call the one I am calling from I get engaged as
expected. So "something" is happening, just not what I expected. I set
the phone book entry to be the number provided by the provider for
that line and the ATA's external IP address.

I must be missing something obvious. I someone has a setup that works
by "dialing" IP numbers please PM me and I will give you a number to
try.

TIA
