For outgoing you don't need to forward any ports so long as your router
does NAT and the firewall rules don't block it.

For incoming it's slightly different. If it's one physical device [eg a
single router, ATA or Asterisk server] with multiple accounts on, the
device should be able to deduce from the info in the inbound call which
account the call is for. SIP calls are a bit like email addresses, the
bit before the '@' is the account that the call is for.

If you've got multiple devices registering their own accounts behind a
single public IP address, you will need to make sure the relevant ports
are forwarded to the relevant devices for them to be able to receive
calls.

Does it work?

That'd be ok then.
It's only multiple outgoing calls that concerned me.

I haven't really tried it in anger.
Currently incoming BT calls are set to divert to 0845 number provided by
voipfone should the bt line be busy. from there both voip ports on the
router ring so should bt line be tied up and port 1 also tied up then
port 2 should get the call.

We don't generally get enough calls to try it and most of the time
there's only 2 of us here anyway.
:¬)

It just seemed that when I was trying to make 2 outgoing voip calls at
the same time I was getting a busy tone, hence the reason for the post.

May just have been a coincidence though.

Cheers
Pete
