FortiVoice unit in realtime.
Once a DHCP-enabled phone connects to the FortiVoice unit and is auto-discovered, the
FortiVoice unit assigns an IP address to the phone and sends the basic PBX setup information
to it.
For the supported DHCP-enabled phone to connect to the FortiVoice unit:
• In the FortiVoice DHCP server configuration, select DHCP option 66 (an advanced option on
the web-based manager) and include the IP address of the FortiVoice interface connected to
the same network as the SIP phones to be auto-provisioned. For more information, see
“Configuring DHCP server” on page 46.
DHCP server option 66 identifies a TFTP server and includes the IP address of the TFTP
server and downloads the TFTP server identity to the device that gets an IP address from the
DHCP server. DHCP option 66 is defined in RFC 2132.
• If using your own DHCP server, set the DHCP server option 66 to the FortiVoice unit’s TFTP
server (Opt66) value. For more information, see “Configuring DHCP server” on page 46.
• If the FortiVoice unit and the SIP phone with an IP assigned by a DHCP server are on
different subnets, proper route should be set to make them reachable.
