server address is required. Connecting to the secondary DHCP server that responds to DHCP
INFORM queries with a requested provisioning server address is one possibility. For more
information, refer to
RFC 3925 . If a single alternate DHCP server responds, this is functionally
equivalent to the scenario where the primary DHCP server responds with a valid provisioning
server address. If no DHCP servers respond, the INFORM query process will retry and eventually
time out.
DHCP Option 66 and Option 43
During the startup, the phone will automatically detect the custom option, option 66 or option
43 for obtaining the provisioning server address. The priority of obtaining the provisioning
server address is as follows: custom option->option 66 (identify the TFTP server) ->option 43.
The IP phone can obtain the Auto Configuration Server (ACS) address by detecting option 43
during startup.
To obtain the server address via DHCP option, make sure the DHCP option is properly
configured on the phone. The option must be in accordance with the one defined in the DHCP
server.
