And after reload ALL your phones are unreachable for 2 minutes!

Imagine you have several thousands devices unreachable for 2 minutes.

How much calls will fail during that time?

	Do not prune all peers, only the peer you wish to reload or eliminate!
Do "sip prune realtime peer peername".  That way you do not lose all the =
other registrations.  I really do not see this as a problem as the =
phones will usually re register quickly or if the user dials any number.
