So on the SPA3102 I have:
- Left port 5160 on Line1 - that is registering nicely.
- On the PSTN settings page I have moved to port 5060. I have done this by adding a colon after the IP address in the proxy field and have updated the separate port field to 5060 too.
I’m still a little confused at the PBX end. I removed the port reference from the trunk variables (as you suggested previously) but am not sure how to tell the PBX trunk to use 5060
