Voice over IP Phone Service

Questions & Answers

Do I need two dataports for VoIP?

No. All of the VoIP phones have integrated LAN and PC ports on the back of the phone. You will have one cable running from the Ethernet port on your PC to the PC port on your VoIP Phone. Additionally, you will have a cable running from the LAN port on your phone to the dataport in your work area. See the VoIP connectivity diagram for details.

I don't hear a dialtone. What do I do?

  1. Make sure you are logged in to your phone. Logging in requires your seven-digit directory number (ie: 882XXXX) and the password provided to you when your phone was installed.
  2. Check to see if all cables are plugged in to their correct ports. Typically, you will have one cable running from the Ethernet port on your PC to the PC port on your VoIP phone. Additionally, you will have a cable running from the LAN port on your phone to the dataport in your work area. You also will have a separate power supply that powers the VoIP phone.
  3. Rebooting the phone often clears up connectivity problems. Simply unplug the Ethernet cable that runs from the dataport to the phone for approximately 10 seconds and then plug the cable back into the dataport. Keep in mind that this will cause a brief network outage to the PC downstream.

Why is my red light on?

A red indicator light located above the VoIP phone display will illuminate (it does not flash like a traditional phone light) when there is a:
  • Missed call to primary phone number
  • Voice mail message waiting
Remember, the indicator light on a VoIP phone does not flash to indicate a voice mail. Once you review the missed calls list and/or listen to voice messages, the light will go off.

What is the difference between "3 Way Call" and "Conference" on my IP phone display?

The "3 Way Call" button is the same thing as "Transfer." It allows users to blind transfer, supervise a transfer to another party or establish a three-way call. The "Conference" button is the same thing as "Conference 6" which is used to conference in as many as five additional parties.

How do I adjust my phone for Daylight Savings Time?

Because Nortel IP phones are used in many locations that don't observe Daylight Savings Time (DST), they feature a separate DST setting which changes the time sent by the phone switch. On most phones:
  • Press Menu
  • Scroll to Time
  • Scroll to Daylight Saving
  • Select "On" for DST
Selecting "On" will increase the time by one hour (spring). Selecting "Off" will decrease the time by one hour (fall).

Is there a call timer available on VoIP phones?

Yes. The call timer is turned off by default. To activate the timer:

  • Press Menu
  • Scroll to Time
  • Scroll to Call Timer
  • Select "On"
The call timer will appear on your display the next time you're participating in an active call.

Where can I find the user guide for my phone?

What type of connectivity is required to deploy VoIP service to an off-campus location?

Off-campus locations must be connected back to campus by fiber in order to support VoIP service at this time. Contact the Division of IT to set up a consultation.
