armstr_a,
I have been creating them as 'Generic SIP' phones not UC Endpoints, and you won't need to manually add the MAC Address. When you setup your phone in the system just make sure that the SIP Password is set and I believe that SIP Capabilities 71 is already pre-configured to work with a UC 360. Then just give it a few multicall keys; at least 3-4 and it should be ready to go.
Then you would go into the UC 360 and tell it to turn on its VLAN settings if you are providing LLDP-MED or CDP, and if you aren't then just manually set it to the correct VLAN or change the port it is plugged into on your switch to be untagged for the voice VLAN. Then you just need to tell it where to find the MiVB system, put in the username [extension] and password [whatever you set it to] and the device should come online.
I don't have the menus of the UC 360 memorized as I don't install that many, but those are the basic steps necessary to make it work.
Thanks,
TE
