Skype for Business, 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.

Power

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 net-trouble@illinois.edu

Network Support

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

The User Sign-on method works with Yealink phones. 

  1. Select User Sign-in from the pull-down list of Login Type field.
  2. Tap the Sign-in Address field. (An on-screen keyboard appears on T48S devices.  T46S and T42S devices use the telephone number pad keys.)
  3. Enter the phone user’s sign-in address (e.g., user@illinois.edu or user@uillinois.edu) in the Sign-in Address field.
  4. Enter the same information (e.g., abc@illinois.edu) in the User Name field.
  5. Enter the phone user's AD password in the Password field.
  6. Tap Sign in.
  7. You will be asked to create a device specific unlock PIN.  This PIN is only used to unlock the device once the inactivity timeout value is reached.  This can be any 6-digit combination.

PIN Authentication method

The PIN Authentication method works with both Yealink and Lync Phone Edition (Polycom CX500, CX600, CX3000; and Aastra/Mitel 6725) devices.

  1. Select PIN Authentication.
  2. Enter the user's 11-digit campus phone number.
  3. Enter the user's UC Lync PIN.  See Skype for Business, How to reset the PIN for information on how to set the PIN.
  4. You will be asked to create a device specific unlock PIN.  This PIN is only used to unlock the device once the inactivity timeout value is reached.  This can be any 6-digit combination.
  5. See Skype for Business, IP Phone Error, Cannot download certificate because domain is not accessible if you receive a message about a certificate error.

Better Together over Ethernet (BToE) software method

The Better Together over Ethernet (BToE) feature on Yealink Skype for Business phones enables you to control call activity from your phones and a Windows computer using the Skype for Business client. You can also use BToE to sign into your phone using your Skype for Business credentials.

Please see Skype for Business, Yealink Better Together over Ethernet (BToE) for detailed instructions on how to install and use the BToE software.

USB Tethered method

The USB tethered method works with Lync Phone Edition (Polycom CX600, CX3000; and Astra/Mitel 6725) devices.  This method requires a computer running Windows. 

  1. Have the Skype for Business for Windows client installed and have the phone user logged in.
  2. Connect the USB cable between the phone and the computer.
  3. Select "Yes" to the question "Do you have a computer available to simplify setting up this phone?" from the welcome screen on the phone (if needed).
  4. The Skype for Business client will prompt for user authentication.  Enter the following information:
    1. Account:  The phone user's SIP address (user@illinois.edu or user@uillinois.edu).
    2. User name:  UOFI\<user>
    3. Password:  The phone user's AD password.
  5. You will be asked to create a device specific unlock PIN.  This PIN is only used to unlock the device once the inactivity timeout value is reached.  This can be any 6-digit combination.
  6. See Skype for Business, IP Phone Error, Cannot download certificate because domain is not accessible if you receive a message about a certificate error.
