Aastra 9000i Series Administrator's Manual page 171

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 6757i phones to use FTP and the 6757i CT phones to use TFTP from
the same server.
Linux Example
A System Administrator can enter the following in the Aastra IP Phone configuration file:
option space AastraIPPhone57i;
option AastraIPPhone57i.cfg-server-name code 02 = text;
option space AastraIPPhone57iCT;
option AastraIPPhone57iCT.cfg-server-name code 02 = text;
Subnet 192.168.1.0 netmask 255.255.255.0 {
class "vendor-class-57i" {
match if option vendor-class-identifier="AastraIPPhone57i";
vendor-option-space AastraIPPhone57i;
option AastraIPPhone57i.cfg-server-name "ftp://
username:password@10.10.10.1";
}
class "vendor-class-57iCT" {
match if option vendor-class-identifier="AastraIPPhone57iCT";
vendor-option-space AastraIPPhone57iCT;
option AastraIPPhone57iCT.cfg-server-name "tftp://10.10.10.1";
}
}
Your DHCP server configuration file, such as the dhcpd.conf file, may include one of these lines
to configure the configuration server protocol and the server details.
