[cisco-voip] Phones not Registering on CME

[Jeff Garvas]

It sounds to me like your phones are in the wrong vlan, thus getting the
wrong IP address and quite possible the wrong or no option 150 information?

If your end users go into the phone settings what Voice/Data vlan is it
claiming to have?  Could it be pointing to something other than the CME you
think its hitting?   Find out from the phone itself which CM / tftp / dhcp
server its communicating with.

If the phone is stuck in configuring IP I'd question what the phone is
learning from DHCP, which may be controlled by the vlan and any respective
helper addresses.
