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?
