Your VoIP Phone

Learn about the basic features of your VoIP phone including placing and receiving calls, settings and acquiring additional equipment for your phone.

On this page:

Connecting Your Phone

All VoIP phones must be connected to network switches. Your phone plugs into the data connection used by your desktop computer and your computer plugs into a connection on the back of your VoIP phone. VoIP phone lines cannot be shared with fax, alarm or modem lines.

You should not plug your phone into a mini-switch or hub, as it causes problems with location reporting for emergency response, security, power survivability and call quality.

Placing and Receiving Calls

To place a call, pick up the handset of your VoIP phone or press its Speaker button, then dial the number.

To answer a call, pick up the handset or press the Speaker button while the phone is ringing. If your phone has multiple lines, select the line that is ringing after picking up the handset or pressing the Speaker button.

To switch from handset to speakerphone during a call, press the Speaker button and put the handset down in its cradle. To switch from speakerphone to handset, lift the handset from the cradle and the speaker function will automatically turn off.

Skipping the Greeting When Leaving Voicemail

To skip the Cisco Unity voicemail greeting when leaving a message on another’s VoIP phone, press #.
