DECT base station Yealink W60B will not register

[KraGwort]

We had a working W60B base station with 2 W53H phones. One of the phones dropped and became unregistered. Worked on it for a while with no luck. Then the base station itself dropped to unregistered. Worked on that for a while with no luck. Deleted the base station from the system, reset the base to factory and re-added as a new device/added the provision address given by the system etc.. Confirmed the firmware for both the base and the phones is the latest offered at Yealink. I just cannot get the base to do something it needs to do. This base and phones are still listed as active by 3cx. They are EOL at Yealink. Any suggestions?

I have not added phones to the base at this point. Adding phones to the base hasn't been the issue thus far however. The base has been unsuccessful registering ever since it dropped the connection back on 9/21.
