When they want to communicate their request to make the connection server. IP PBX has a directory database or music or all users in the corresponding SIP address. When a request from the IP Phone, the first IP address resolved by Sip address or extension is not. in IP PBX and then sent to the destination. So, in direct call routing routing outgoing calls via VOIP Gateway made. Analog Station Gateway allows fax machines to connect to the IP PBX.

The phone can talk to the Call Manager and registers itself. Stores Call Manager IP-address-to-phone map (and vice versa) in the table. When the user wants to call another user, he would call the called party's phone number. Call Manager to check the SIP address dialed telephone number search purposes.
Then complete the destination IP address and generate IP packet tone ring version is called IP phone through the TCP connection. When the called IP phone receives the packet, producing a ringing tone. Now users receive a call, Call Manager instruct the IP phone is called to start talking eliminate themselves from the loop. From now on, the call between two IP phones.
When any change occurs in the phone because it features one of the pressing device, or one user hangs up, the information coming through Call Manager Control Channel. PSTN to IP Phone calls relationship: If a call is made from the IP-PBX several networks, calls Call Manager Analogue or digital trunk gateway which in turn through the PSTN network. Call PSTN telephone network spreading right. Calls from PSTN network is also sent via analog or digital trunk gateway, and then the call is sent to the Call Manager. NOTE: - SKYPE calls will be one of the openings of data networks and the Internet, and then taken to the introduction of the relationship Call Manager.
