On the **VOSS Phones** page, phones are associated with
the VOSS Phone Server (see *Introduction to VOSS phone server* and *Managing VOSS phone servers* in the Core Feature Guide. 

* **Vendor**: all vendors configured in the library of phone types are offered. See *Add phone types* in the Core Feature Guide.
* **Model**: the phone model is selected. See See *Add phone types* in the Core Feature Guide.
* **Number of Lines**: available number is chosen.

These parameters are used to determine the template to use when creating
the phone configuration file on the TFTP server.

* **Phone MAC Address**: required, with no vendor prefix as would be used with CUCM. E.g use ``123412341234``, not ``SEP123412341234``.
* **Group**: is selected. This represents the SIP realm to use for registration.
  Typically there will be a single realm or group for a customer, although more
  advanced configuration is possible and may be added to the Phone Server.
* **Line**: each line has the following parameters:

  * **Number**: The directory number from number inventory. Numbers can exist on Phone server phones or CUCM phones, but not both.
  * **Display Name**: The display name for presentation when making a call
  * **Busy trigger**: As per CUCM phones
  * **Max Calls**: As per CUCM phones
  * **Class of service**: This is the class of server as created by the CUCM dialplan. CoS is enforced on CUCM when using HCS mode.
