NTP (Network Time Protocol)
The Network Time Protocol (NTP) is used to synchronize the time
of the system with 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.
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.
SIP
Determines whether the system should be able to place and receive SIP
calls.
On: Set to On to enable the possibility to place and receive SIP
calls. This is the default setting.
