Advanced Settings
HTTPS test certificate: Set to On or Off.
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.
Off: Set to Off to disable the possibility to place and receive SIP
calls.
SNMP (Simple Network Management Protocol)
Used in network management systems to monitor network-attached
devices (routers, servers, switches, projectors, etc) for conditions that
warrant administrative attention. SNMP exposes management data in the
form of variables on the managed systems, which describe the system
configuration. These variables can then be queried (set to ReadOnly) and
sometimes set (set to ReadWrite) by managing applications.
Community name
Enter the name of the Network Services SNMP Community. SNMP
Community names are used to authenticate SNMP requests. SNMP
requests must have a ‘password’ (case sensitive) in order to receive a
response from the SNMP Agent in the codec. The default password
is “public”. If you have the TANDBERG Management Suite (TMS) you
must make sure the same SNMP Community is configured there too.
Note! The SNMP Community password is case sensitive.
Host IP address
Enter the IP address of the SNMP Manager. All traps will then be sent
to the host listed.
The system’s SNMP Agent responds to requests from SNMP
Managers (a PC program etc.). SNMP Traps are generated by the
SNMP Agent to inform the SNMP Manager about important events.
Can be used to send event created messages to the SNMP agent
about different events like: system reboot, system dialing, system
disconnecting, MCU call, packet loss etc. Traps can be sent to
multiple SNMP Trap Hosts.
Mode
Off: Set to Off when you want to disable the SNMP network
service.
ReadOnly: Set to ReadOnly when you want to enable the SNMP
network service for queries only.
ReadWrite: Set to ReadOnly when you want to enable the SNMP
network service for both queries and commands.
System contact
Enter the name of the Network Services SNMP System Contact.
