SUB-OPTION/CODE

The System administrator can use the Vendor Class Identifier to send the phone a customized
Server Configuration in option 43 (Vendor-Specific information).
Note: If Mitel IP Phones receive the server configuration from both DHCP Option 66
and DHCP Option 43, then Option 43 takes precedence over Option 66.
Using Option 43 to Customize the IP Phone
A System Administrator can customize the IP Phone(s) in the network by entering a text string
in the phone's configuration files. The following is an Option 43 example using Linux.
On the startup of the phones, when the DHCP server receives the request with the information
in this example, it allows the 6867i phones to use FTP and the 6869i phones to use TFTP from
the same server.
Linux Example
A System Administrator can enter the following in the DHCP server:
option space AastraIPPhone6867i;
option AastraIPPhone6867i.cfg-server-name code 02 = text;
option space AastraIPPhone6869i;
option AastraIPPhone6869i.cfg-server-name code 02 = text;
Subnet 192.168.1.0 netmask 255.255.255.0 {
class "vendor-class-6867i" {
match if option vendor-class-identifier="AastraIPPhone6867i";
vendor-option-space AastraIPPhone6867i;
option AastraIPPhone6867i.cfg-server-name
"ftp://username:password@10.10.10.1";
}
class "vendor-class-6869i" {
match if option vendor-class-identifier="AastraIPPhone6869i";
vendor-option-space AastraIPPhone6869i;
option AastraIPPhone6869i.cfg-server-name "tftp://10.10.10.1";
}
}
