What Did You Do To Active IP Phone In Your Network System ?

I must have CUCM or at least cisco call manager express to register the IP phone and manage the DN and route patterns

register the phone at the call manager after connected to the active network

Add the phone using BAT to the CUCM, connect the phone to the POE switch, once the phone is powered up enter the username and password for the phone to contact the TFTP server and download the configuration file.

Hi Abbas. 

i didn't really understand your question , but if you mean what do you need to have an IP phone in your network? it depends on your requirement and the brand you want to work with. 

lets say you decided to go with Cisco. 

first you must have a voice controller , and Cisco Call Manager Devices installed in your network 

then you must have PoE Switches , it will be used for the communication and to support the IP Phones with Power in the Same time, also you have to configure the switches with 2 VLANS  ( one for DATA Communication , and the other one for Voice Communication ) 

in regards to the IP Phone Power Support , you can use power adapter with the phone but you must then install a power adapter for every phone device in the company. 

Hope that answer your question :)
