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.
Setting Time Server Using the Configuration Files

of Time Servers 1, 2, and/or 3.
