5.8.2.6 IP Services
NTP IP
This is the NTP time server address from which the system can get updated time information.
This is a requirement for proper operation if H.235
authentication is implemented.
The Network Time Protocol (NTP) is used to synchronize the time of the system to a reference
time server. The NTP IP setting holds the IP address to a time source where the system can get
the exact time. The time server will subsequently be queried every 24th hour for time updates.
The system will use the time to timestamp messages transmitted to Gatekeepers or Border
Controllers requiring H.235 authentication.
