2.11 Appendix D: Configuration of External DHCP Server

Configuration of External DHCP Server
Note: - Although the SV9100 supports DHCP Server functionality, it is only designed for demonstration
or test purposes. Please be aware that no support can be offered if the DHCP Server is used on a
customer's site.
It is possible to use either an external DHCP server (e.g. Windows 2003 Server) or the SV9100 internal
DHCP server, to provide IP details to the DT800/DT700 IP phones.
If you are using an external DHCP server, it is necessary to add a new Option Code to the DHCP scope for
the SIP Server. The method for adding this service varies dependent on the DHCP server used.
The example below shows the necessary steps to add Option 120 (SIP Server) to a Windows 2003 Server.
1. Enter DHCP via Administrative Tools.
2. Right click on the relevant DHCP server and click on "Set Predefined Options".
3. When the "Predefined Options and Values" dialogue box opens, click on Add.
4. Enter the information below in to the Option Type dialogue box.
