The calls are made over an IP network like Internet or can be made via a companies private IP network.  IP Phones uses protocols allowing callers to view the individual on the other line, and can be viewed by those they are calling.

• phyical hardware (earpiece, keypad, display screen, etc); 
• DNS client, STUN client, DHCP client; 
• video & audio capabilities; and,
• a friendly user interface. 

These elements make up the internal system of an IP Phone.
