Hi,
it sound like your phones don't get any connection from Internet side.

If you have a STUN Server configured you should be fine if do the following:
(STUN needs to be allowed from LAN to WAN (Internet) 3478 TCP/UDP)

If you can configure every handset with its own set of ports (like 5061 and 10000-10025 for one handset)
Create an Alias with with the handsets IPs (they have to be static or reserved IPs from DHCP)
Enable Hypbrid Outbound NAT
Add a Rule (WAN interface, source is above alias,  Static-port: checked)

This should do the trick

You could also make port forwards but only if you have youre on set of ports for every handset configured.
(Filter rule association: pass; NAT Reflcetion Enabled)

Thanks for this, solved my VoIP issues with my SPA112. STUN server didn't work for me, but the NAT Rule fixed it!
