If we want to set priority means if phone first try to register with sub2,3 and then 1 then where we set priority in cucm

[@TechnicalVenture]

When you create CUCM group you will define subscribers there, The subscriber which is at top gets the first priority.

[@vinaykb613]

How does switch know how much power need to be suppy to the cisco ip phone?

[@TechnicalVenture]

That depends on the Class of Phone, Whether its a Class 1 or 2 and so on. Cisco Phone Models divides into Different Class type and depends on that Switch will supply the power

Great, but could you please explain the meaning of a call processing server? what is a call processing server
Thanks

[@TechnicalVenture]

Call Processing Server is your Subscriber on which we activate the Cisco Call manager Service through which your calls will process and Your phones also get registered on call processing Servers.. We can even use our PUB as a Call processing server as well you just need to activate the CM service. Generally we do not make our PUB as a call processing server as PUB has so many other things to do.
