The Network Time Protocol (NTP) is used to synchronize the time of the system to a reference time
server. The time server will subsequently be queried every 24th hour for time updates. The time will be
displayed on the top of the screen. The system will use the time to timestamp messages transmitted
to Gatekeepers or Border Controllers requiring H.235 authentication. The system will use the time
to timestamp messages transmitted to Gatekeepers or Border Controllers that requires H.235
authentication. It is also used for timestamping Placed Calls, Missed Calls and Received Calls.
Requires user role: ADMIN
Value space: <Auto/Manual>
Auto: The system will use the NTP server, by which address is supplied from the DHCP server in
the network. If no DHCP server is used, or the DHCP server does not provide the system with a NTP
server address, the system will use the static defined NTP server address specified by the user.
Manual: The system will always use the static defined NTP server address specified by the user.
Example: xConguration NetworkServices NTP Mode: Manual
NetworkServices NTP Address
Enter the NTP Address to define the network time protocol server address. This address will be used if
NTP Mode is set to Manual, or if set to Auto and no address is supplied by a DHCP server.
Requires user role: ADMIN
