An IP telephone
Before you configure VoIP, be sure you have:
Installed the switch. See the installation instructions for your switch.
Performed the initial switch configuration. See "Connecting and Configuring an EX
Series Switch (J-Web Procedure)" on page 201.
Performed basic bridging and VLAN configuration on the switch. See "Example: Setting
Up Basic Bridging and a VLAN for an EX Series Switch" on page 1525.
Configured the RADIUS server for 802.1X authentication and set up the access profile.
See "Example: Connecting a RADIUS Server for 802.1X to an EX Series Switch" on
page 2765.
(Optional) Configured interface
configuration is not necessary if the VoIP supplicant is using a power adapter. For
information about configuring PoE, see "Configuring PoE (CLI Procedure)" on page 3543.
NOTE: If the IP address isn't configured on the Avaya IP phone, the phone
exchanges LLDP-MED information to get the VLAN ID for the voice VLAN.
You must configure the
interface as a VoIP interface and allow the switch to forward the VLAN name
and VLAN ID for the voice VLAN to the IP telephone. The IP telephone then
uses the voice VLAN (that is, it references the voice VLAN's ID) to send a
DHCP discover request and exchange information with the DHCP server
(voice gateway).
Instead of using a regular telephone, you connect an IP telephone directly to the switch.
An IP phone has all the hardware and software needed to handle VoIP. You also can
power an IP telephone by connecting it to one of the Power over Ethernet (PoE) interfaces
on the switch.
