• Serial Number — device serial number defined by the manufacturer;
• System Time — current date and time defined in the system;
• Uptime — time of operation since the last startup or reboot of the device.

"Conntrack" submenu

In the "Conntrack" submenu you can find the current active network connections of the device.

Active NAT session

• Active Connections Count — total number of active network connections.
• Shown Connections Count — number of connections shown in the web interface. In order to maintain high performance of the web interface, maximum number of connections shown is limited to 1024. You can view other connections with the device command console (cat /proc/net/nf_conntrack).

List of Connections

• Protocol — protocol that the connection is being established through;

• Source Address — source IP address and port number;

• Destination IP — destination IP address and port number;

• Timeout — time period until the connection termination.

To obtain the current information from the device, click button.

View the route table

In the "Static Routes" submenu you can view the device route table.

• Destination — IP address of destination host or subnet that the route is established to;
• Gateway — gateway IP address that allows for the access to the "Destination";
• Genmask — subnet mask;
• Flags — specific route attributes. The following flag values exist:
  • U — means that the route is created and passable;
  • H — identifies the route to the specific host;
  • G — means that the route lies through the external gateway. System network interface provides routes in the network with direct connection. All other routes lie through the external gateways. 'G' flag is user for all routes except for the routes in the direct connection networks;
  • R — means that the route most likely was created by a dynamic routing protocol running on a local system with the 'reinstate' parameter;
  • D — means that the route was added on reception of the ICMP Redirect Message. When the system learns the route from the ICMP Redirect message, the route will be added into the routing table in order to exclude redirection of the following packets intended for the same destination. Such routes are marked with the 'D' flag;
  • M — means that the route was modified — likely by a dynamic routing protocol running on a local system with the 'mod' parameter applied;
  • А — means buffered route with corresponding record in the ARP table;
  • С — means that the route source in the core routing buffer;
  • L — means that the route destination is an address of this PC. Such 'local routes' exist in the routing buffer only;
  • В — means that the route destination is a broadcasting address. Such 'broadcast routes' exist in the routing buffer only;
  • I — means that the route is related to the loopback interface. Such 'internal routes' exist in the routing buffer only;
  • ! — means that datagrams sent to this address will be rejected by the system.
• Metric — defines route cost. Metrics allows you to sort the duplicate routes, if they exist in the table;
• Ref — identified number of references to the route for connection establishment (not used by the system);
• Use — number of route detections performed by IP protocol;
• Interface — name of the network interface that the route lies through.

View Call History

In the "Call history" submenu you can view the list of performed phone calls and the summary for each call.

The device RAM can store up to 10,000 records for performed calls. If the record number exceeds 10,000, the oldest records (at the top of the table) will be removed, and new ones will be added at the end of the file.

Call log statistics will not be collected, when the history size is zero.

"Call history" table field description:

• # — sequence number of the record in the table;

• Line — device subscriber port number;

• Local number — subscriber number assigned to the current subscriber port;

• Remote number — remote subscriber number that the phone connection has been established with;

• IP address of the opposite side — remote subscriber IP address that phone connection has been established with;

• Start call time — call received/performed time and date;

• Start talk time — call start time and date;

• Talk duration — call duration in seconds;

• State — transient state or reason for call clearing; description becomes available, when you hover the cursor over the call state record;

• Type — call type: outgoing or incoming;

• TxPack — number of RTP packets sent during the call;

• TxBytes — number of bytes sent during the call;

• RxPack — number of RTP packets received during the call;

• RxBytes — number of bytes received during the call.

In the call history table you can search records by different parameters; to do this, click the 'Filter (show)' link. Filtering can be performed by the subscriber line address, local or remote number, opposite side IP address, call received time, call start time, call state and call type. For filtering parameter description, see call history table field description above.

• Call received time from/to or Call start time from/to — call received/performed time period or call start time period in the 'hh:mm:ss dd.mm.yyyy' format.

To hide the table record filtration parameter settings, click the 'Hide' filter link.

To configure call history parameters, click 'Configure call history parameters' link. For detailed parameter configuration description, see "Phonebook" submenu.
