CM Lists!! Help!!

[planetmaker]

We have one site that has a its own device pool locations etc - 65% of the phones are (all of a sudden) not registrering. They seem stuck on "Configuring CM lIst"

Can some one explain why this may be?

I have deleted one that is n't working add manully added it again but still no joy I have even deleted its ip address but doesn't seem to want to pick up a new one.

Seems strage that some are ok others not and its not a connection issue.

I added some phone via the BAT tool yesterday and they will not register either (different location)

However they come back up if weplug them in on our subnet

Please Help this is Service Critical

Callmanager version`? IP-Phone load version?

klick on one of the phone: Setting->status-> check 1 and 2 and past the errors here. Also check Setting->Networkconfiguration see if there is something missing. on the Server side check the Eventviewer (trace SDI and SDL).

Check your dhcp, option 150 should point to your CCM. Try to ping CCM from the remote IP phones lan.
