Configuring Network and Session Initiation Protocol (SIP) Features
The System administrator can use the Vendor Class Identifier to send the phone a
customized Server Configuration in option 43 (Vendor-Specific information).
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 ";
}
}
Note: If Aastra IP Phones receive the server configuration from both
DHCP Option 66 and DHCP Option 43, then Option 43 takes precedence
over Option 66.
