7e. To add an entry for an IP phone, configure Endpoint Type, Product ID, Names, Phones, and
Security code fields as indicated below. Configure Phones and Security Code to match the values
configured for this IP phone in Communication Manager. Leave the other fields blank. One entry
is required for each IP phone located at the same site as this MultiVOIP. Do not create entries for IP
phones located at other sites. They will not be able to register with this MultiVOIP in the event of a
wan link failure. Click OK to save this entry. Repeat the above steps to add additional IP phone
entries. The MVP210, MVP410, and MVP810 support 5,10, or 15 IP phones respectively.
The IP phones must be configured to use DHCP and the DHCP server must be located at the same
site as the MultiVOIP and IP phones. This is the only means by which the IP phones are made aware
of alternate gatekeepers, such as the MultiVOIP gatekeeper when the CM is unavailable due to WAN
link failure.
Refer to the following Avaya documents for instructions on how to configure the DHCP server.
