If you want to use the PoE functionnality of the Cisco 3560 switch, apply the following configuration to the switch interface connected to the phone :
Switch(config)#int fastEthernet 0/1
Switch(config-if)#power inline auto
Place calls with 7960 IP Phone
The 7960 IP Phone emulated in Packet Tracer 7.2.1does not have any configurable options. It receives it's IP address through DHCP and it's line number from the Call Manager Express server.
In the GUI tab, you can place a call, answer a call, and send Do, Re, and Mi notes to the recipient phone. To place a call enter the recipient's line number first using the keypad and then click on the handset to dial out.
To answer a phone call on the analog phone, click on the handset when the phone is ringing. While the line is connected, you can send Do, Re, or Mi to the recipient by pressing the respective buttons. In order to hear the sounds, be sure Sound is enabled in Preferences. To end a call, click on the handset.
Home VOIP device
The Home VoIP only has a "Server Address" configuration in which you have to place the Call Manager Express IP address.
Cisco IP Communicator software
The IP Communicator software is installed on desktop or laptop end devices. Configure the computer for DHCP address assignment and use the "Desktop" tab to access the IP Communicator software. The software will receive it's phone line number from the Cisco Call Manager Express server.
To place a phone call, enter the number of the recipient phone using the keypad and then click the Dial button. Once the recipient has answered the call, the status message will indicate that the Cisco IP Communicator is connected and a green light will show. While the call is still active, click on the Do, Re, or Mi buttons to send the respective sounds to the recipient. To end the call, click the EndCall button. For the best possible experience while making calls, be sure that Sound is enabled in Preferences.
If you want configure the Cisco IP Communicator to use a different TFTP server from the default TFTP server, follow these steps. On the upper right-hand corner of the Cisco IP Communicator GUI, there are four buttons above the words "Cisco IP Phone." Click on the first button from the left to open a context menu and then select Preferences. Select the option Use these TFTP Servers: and then enter the IP address of the TFTP server that you wish to use.
