II- To perform a FACTORY RESET
Step 1 Unplug the power cable from the phone and then plug it back in.
The phone begins its power up cycle.
Step 2 While the phone is powering up, and before the Speaker button flashes on and off,
press and hold #.
Continue to hold # until each line button flashes on and off in sequence in amber.
Step 3 Release # and press 123456789*0#.
You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.
After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the main screen appears.
Configure IOS Switch – for Ip Phone
When connecting an Ip Phone to a switch the best way to do it is using the correct users PC connection. This helps to cut down on the costs of cables and ports needed. This is similar to a trunk however it lowers the CPU usage required by the switch.
To do this one you need a POE port on a switch with IOS running.
- Connect to the switch.
- Get to Enable mode
- Run the fallowing commands.
Switch#configure terminal
Switch(config)#interface (My Port Goes Here)
Switch(config-if)#switchport mode access
Switch(config-if)#Switchport access vlan 104
Switch(config-if)#switchport voice vlan 50
Done, that's it. Now connect the phone to switch and the PC to the phone. Do not forget to save the config.
