VoIP not working with our Balance 305's

We have Ooma GRP2602P VoIP phones installed on our ships for crew use.

The phones stopped working some time ago. If we plug the phone directly into our Starlink router, it works fine, but if we connect it to the rest of the network - all controlled by our Balance 305 - we get nothing.

We tried different SIP settings, and adding every possible Ooma port/protocol to the inbound and outbound firewall settings…no change.

305 firmware is up to date.

What onto have this setting set for SIP. Try changing it and trying again.

SIP ALG causes many issues with VoIP phones. Compatibility mode solves it

We tried Compatibility Mode, and quite a few custom port settings specific to Ooma…no change.
