    Cisco Unified IP Phones and telephony networks The Cisco Unified IP Conference Phone 8831 enables you to communicate by using voice over a data network. To provide this capability, the conference phones depend upon and interact with several other key Cisco Unified IP Telephony components, including DNS and DHCP servers, TFTP servers, and switches.

  • Page 46: Interaction

    When VVLAN is set to 0, 802.1p is enabled. The egress SW port packets will be tagged with 802.1p. On the ingress side, both 802.1p tagged packets and untagged packets are accepted. For more information, see the documentation included with a Cisco switch. You can also access switch information at this URL: http://www.cisco.com/en/US/products/hw/switches/index.html...

    The TFTP server stores the conference phone configuration files that define parameters for connecting to Cisco Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications Manager that requires the conference phone to be reset, a change is made to the conference phone configuration file automatically.

  • Page 50: Phone Startup Process

    4 Obtain an IP address . If the Cisco Unified IP Conference Phone uses DHCP to obtain an IP address, the phone queries the DHCP server to obtain one. If you do not use DHCP in your network, you must assign static IP addresses to each phone locally.

  • Page 51: Cisco Unified Communications Manager Ip Phone Addition Methods

    Cisco Unified Communications Manager IP Phone addition methods Before installing the conference phone, you must choose a method for adding conference phones to Cisco Unified Communications Manager database. Be aware that each phone type requires a fixed number of device license units and the number of unit licenses that are available on the server may impact phone registration.

  • Page 52: Autoregistration Ip Phone Addition

    • Move autoregistered conference phones to new locations and assign them to different device pools without affecting their directory numbers. Cisco recommends that you use autoregistration to add fewer than 100 conference phones to your network. Note To add more than 100 conference phones to your network, use the Bulk Administration Tool (BAT).
