Teams, IP Phone Installation and Login

This document provides information about IP Phone installation for unit IT Pro's. An IP phone is a hardware-based phone for making telephone calls using an Ethernet connection, without requiring a computer to function. IP phones need to be plugged into a network / data jack instead of the traditional voice jack.


IP phones require external power. The majority of installations will require AC adapters or PoE Injectors. 

While we recognize the ease of deployment that PoE offers for IP phones, campus network is not currently positioned to offer PoE to all voice devices. The majority of the campus network lacks the equipment and facilities necessary to provide a large amount of PoE beyond what has been installed to serve Wireless Access Points and security cameras. Locations designated as conference rooms (not offices used as conference rooms) and areas where IP phones will be used as common area or courtesy phones will be eligible for PoE where the network equipment supports it. If PoE injectors are used they should to be installed at the client end of the connection and not placed in the Communication Equipment Room (CER). If you have specific questions regarding PoE, please contact Technology Services Networking at or if you if you have access to the ticketing system direct your ticket to the UIUC-TechServices-Network Operations (Group).

Network Support

It is recommended that IP phones should be on their own VLAN, called the Voice VLAN (network).  Using a Voice VLAN has the following benefits:

  • Traffic separation so IP phones don't receive broadcast traffic from building networks.
  • IP phones are on a private, campus IPv4 space, this not using routable IPv4 from building networks.
  • DHCP options required for IP phones won't conflict with departmental DHCP options.

Network switch configuration:

  1. Login to Iris.  You will need read/write access to the network. See Networking, Iris, Who Can Use Iris?  for information on access to Iris. 
  2. Check to make sure the voice network is available on the switch.  Go to Iris | Switch View | Patch Cords and you should see a column named "Voice".  The Voice column will be available only on switches that have a voice network configured.
  3. Add the voice network to a port by selecting the Voice checkbox.  Selecting the checkbox leaves the port on the existing departmental network.  When an IP phone is plugged in, the phone gets an IP address on the voice network based on LLDP transactions between the phone and the switch.  When any other device is plugged in to the port, it will communicate on the department network.  When a device is plugged into the IP Phone via a "PC" or "LAN" port, the device will communicate on the department network.
  4. Important and Required: Enter or verify the Jack that the switch port is plugged into. This is required for E911 location.  See Networking, Iris Scenarios: Working with Jacks  for information on working with Jacks.  Port-to-Jack mapping requirement is outlined in the Low Voltage Media Installation policy in the Campus Administrative Manual. 

IP Phone Firmware Updates

Once the phone is provisioned on the Voice network, it may automatically download firmware updates.  No IT Pro or User intervention is required.

Logging In to the Phone

Once the user is logged on to the phone, the device will remember the user's authentication info.  They should not need to re-login unless the phone is reset.

User Sign-on method

1) Sign in using the web
Your device should automatically come up to a screen with steps to get you signed in via the web.

Step 1 – One your computer or mobile, go to

Step 2 - Enter the code below to sign in.

    • The code will be on your IP Phone screen. If it has expired, you will see a button that says "Refresh code". Click it to get a new code.

 2) Sign in directly on the device

Below the web login steps, your phone should say “Sign in on this device”. Tap on that line to start the sign in process directly on the phone. The phone will present an on screen keyboard to use during the sign in process, but you can plug in a USB keyboard if that is easier.
