Configuring Operational Features

A time server is a computer server that reads the actual time from a reference 
clock and distributes this information to the clients in a network. The time server 
may be a local network time server or an internet time server. The Network Time 
Protocol (NTP) is the most widely used protocol that distributes and synchronizes 
time in the network with the time on the time server.

On the IP phones, you can enable or disable a Time Server to be used to 
synchronize time on the phones with the Timer Server you specify. An 
Administrator can use the IP Phone UI, Aastra Web UI, or configuration files to 
enable/disable the Time Server and specify a Time Server 1, Timer Server 2, and/
or Time Server 3. A User can enable/disable the Time Server using the IP Phone 
UI or Aastra Web UI only. The Time Server is enabled by default.

Use the following procedure to enable/disable the Time Server and optionally set 
the IP Address of Time Servers 1, 2, and/or 3.

Use the following procedure to set the Time Server and optionally set the IP 
Address of Time Servers 1, 2, and/or 3.

For specific parameters you can set in the configuration files, see Appendix A, the section, 

page A-52.
