Time Servers
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.
