I figured out the issue, we had a router, routing to another router, which was then connected to the ip phone. Rather than mucking about with port forwarding, we just plugged the phone directly into the top level router and it worked perfectly

Hi @Ruairidh

I'm glad to hear you connected it directly in the end, that would indeed cause problems.

But you still need port forwards for your STUN phone, because sooner or later you will have problems again.

Alternatively, you can install an SBC and forget about port forwarding entirely.
