In the 3CX is see the extension as not registered and other phones cannot contact that extension anymore when it appears as not registered. When I look in the T46 status page it says the extension is still registered.

I am using 3CX version 14 with latest updates.
There are 9 other phones connected to that PBX, all in the same office and network and they all work fine. The other phones are Cisco's and Yealink T41's.

The T46 has its IPv4 config set to manual (as all other phones do also).
Extension 1 and 2 have exactlty the same settings on the accounts page (other than their username and password).

Can you tell me the firmware version of T41P and T46?
I think it's better that you can apply the trace files for us to check more.

And suggest you can descrease Server Expires then test agian.
