26 9600 Series SIP IP Telephones Administrator Guide SIP Release 2.0
Server Requirements
Four server types can be configured for the 9600 Series IP Telephones:
● DHCP server
● HTTP or HTTPS server
● SIP Proxy or Registration server
● Network Time Protocol server for SNTP
Note:
Note: 9600 Series SIP IP Telephones need SIP Enablement Services (SES) to work
properly. The SIP Proxy and Registration servers reside on the SES server.
Avaya Communication Manager (CM) is considered a “feature server” behind
SES that provides Outboard Proxy SIP (OPS) features. SIP software Release 2.0
supports both SES 4.X and 5.X, but when the corresponding server is running
SES 4.X, the telephones assume only those features compatible with SES 4.X.
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 network information
whereas HTTP provides configuration and application file management, yet both functions can
co-exist on one hardware unit. Any standards-based server is recommended.
For parameters related to Avaya Communication Manager information, see Chapter
4: Communication Manager Administration. For parameters related to DHCP and file servers,
see Chapter 6:
Server Administration.

Important:
Important: The telephones obtain important information from the script files on the server(s)
and depend on the binary file for software upgrades. If these servers are
unavailable when the telephones reset, the telephones will not operate properly.
Some features might not be available. To restore them you need to reset the
telephone(s) when the file server is available.
DHCP Server
Avaya recommends that a DHCP server and application be installed and that static addressing
be avoided. Install the DHCP server and application as described in DHCP and File Servers
