I had tried the grand reset to no avail. Was hoping for an even grander
reset.
Phones function well enough.

Oh well. So much for the easy fixes.

Mostly curious about the service "port" as I my old stand alone answering
machine is working compatibly at the moment.

My guess(tm) is that it's a JTAG port used to load firmware and
initialized (serialize) the phone. I did some Googling but didn't
find anything specific for Vtech DECT phones. If you succeed in
finding or building an RS-232 converter for interfacing to the port,
you'll probably find a rather primitive command set, no help, no
menus, and cryptic commands and incantations. It will also lack any
easy way to recover from mistakes. Y're welcome to try it, but
methinks it's not worth the effort. However, you might want to open
the base and inspect the base for crappy soldering.
