Network Requirements
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:
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
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:
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 on page 53.
