I am looking for some advice to get 2 phones registered in Call manager. I have 2, only 2 connected that I'm trying to get up and working in my Lab. CM shows them as never being seen, but I can edit the lines on the phone.. Add, delete, change DN's and so on..
-
Under Device -> Phone I have 2 listed both say “none” under status and if I open each one Register says “unknown”
-
I can add, update, and delete Directory numbers both of them.
-
When the phones boot up they run thru:
Configuring VLAN -> Configuring IP -> TFTP Loading -> Configuring VLAN -> Configuring IP -> Requisition configuration then to a screen that says Cisco Systems and “Your Current Options” is continuously flashing across the bottom of the display -
I can pick up the hand set and get a dial-tone, but when the “your current options” flashes the dial tone stops, it’s like the phone is reset.

Best Answer
Another possibility is that the phones were receiving incorrect Voice VLAN or DHCP settings (option 150 TFTP server in particular), ore were otherwise unable to contact the CUCM server at 192.168.10.5 and so were unable to register and receive configuration data. This could be as simple as a misconfigured switch port or, since CUCM is running in a VM, incorrect host/VM network bridging.
