The TFTP provisioning server or the DHCP server can provide the
automatic Provisioning Info Block. The servers share the same syntax
defining the Provisioning Info Block. The TFTP provisioning server
provides the Provisioning Info Block in a set of .PRV files, where the
DHCP Server provides the Provisioning Info Block with a new Vendor
Specific String Nortel-i2004-B.
Operation
This section describes the automatic provisioning feature operation.
Precedence rule and stickiness control
The IP Phone 2007, IP Phones 1100 Series, and IP Phones 1200 Series
can obtain provisioning information from many sources at various times. A
precedence rule can resolve the possible conflict when different values
are specified in various sources for one parameter. The IP Phone 2001,
IP Phone 2002, and IP Phone 2004 do not support the precedence rule,
therefore the phones use the last value received.
