## Server Requirements

Three server types can be configured for the 9600 Series IP Telephones:

- DHCP
- HTTP or HTTPS
- Web (optional)

While the servers listed provide different functions that relate to the 9600 Series IP Telephones, they are not necessarily different boxes. For example, DHCP provides file management whereas HTTP provides application management, yet both functions can co-exist on one hardware unit. Any standards-based server is recommended.

For parameters related to Avaya Media Server information, see Chapter 4: Communication Manager Administration, and the administration documentation for your call server. For parameters related to DHCP and file servers, see Chapter 5: Server Administration.

CAUTION: The telephones obtain important information from the script files on the file server and depend on the application file for software upgrades. If the DHCP file server is unavailable when the telephones reset, the telephones register with the media server and operate. Some features might not be available. To restore them you need to reset the telephone(s) when the file server is available.
