Has anyone had any past experience with getting a network busy message on the IP phone, then they restart.

I can't seem to find any fault on the network itself... the main change is the fact we have recently added a few more IP phones to the network.

The issue occurs on multiple floors, but not all IP phones, only some.

Any insight would be appreciated.

The IP phone will re-register if it doesn't get a reply back from the SV8300 in time.

There are a timers you can tweak if needed.

Are they the same phones having this issue? If so what is different from the others not having the issue, somethings got to be different
Are there multiple switches?
Are the cables going from the patch panel to station jack all the same?
Some cables and connectors could be cheap grade cat 5 while others could be cat 6

Just some things to give you a idea.
