Do you have the siproxd package installed on pfsense? It is suspossed
to handle registrations from multiple phones behind NAT. In your case
since the phones are external I would probably remove it if installed.
I haven't needed siproxd.

Also on Asterisk set externip to your static IP in sip.conf. Or if you
don't have a static IP set externhost. You also need to configure
localnet.
