That doesn't seem to have helped entirely.

The "Password" prompt no longer appears but the phone still becomes
UNREACHABLE then UNKNOWN after a few minutes.

In the system information on the phone it reports "Registration Failed".
However a few minutes later it logs itself back in.

I have two identical snoms on the bench here and they both do the same
thing, logging in and operating fine, before eventually (but not
necessarily at the same time) losing registration and stopping for a few
minutes.
