Static Routing Configuration

  • Domain name
    Displays the domain name that should be used for the static routing entry. The domain name establishes the context for the hierarchical system and must be unique in your displayed list.

  • Access server
    Shows the IP address of the server under which the domain is accessible. It can also be a symbolic name which was converted into an IP address.

  • Port
    Enter the port number for the selected access server. Values between 0 and 65535 may be entered for the port number. Many SIP servers use Port 5060 over TCP or 5061 over TLS. The port number and the transport protocol must correspond to a network interface for incoming connections from the access server.

  • Bind to IP address
    Select the IP address from the list of available IP addresses, which you would like to use for the static routing entry. You may only select from the entries in the list. The selection options will depend on your system settings.

  • Transport Protocol
    Choose the transport protocol for the access server. The transport protocol and port number must correspond to a network interface for incoming connections from the access server. The following transport protocols are available for static routing:
    - UDP (User Datagram Protocol)
    - TCP (Transmission Control Protocol)
    - TLS (Transport Layer Security)
    - MTLS (Mutual Transport Layer Security)

    For using the MTLS protocol, you will need a server certificate issued for your system. The server certificate must have been issued by a reliable certification authority. You can select an appropriate certificate from Network Settings.

    Please note that UDP and TCP are unencrypted protocols, which have not been secured against eavesdropping. Using these protocols only in a local area network is recommended. The UDP protocol is not recommended because of the maximum packet size of 65,535 bytes.

  • Activate static route
    Activates, or deactivates, static routing. Click the checkbox to activate static routing. In this case, the checkbox will be checked. Click on the checkbox again to deactivate static routing. In that case, the checkbox will not be checked. The setting of this property will correspond to the Enabled column in the static routing list.

  • Classify route as trustworthy
    Mark this checkbox if you classify the static route as trustworthy. Click on the checkbox to activate the functionality. The checkbox is then marked. Click on the checkbox again to deactivate the feature. In that case, the checkbox will not be checked. A static route entry marked as unreliable will require the use of the SIP registrar for the authorization of incoming SIP messages. Static routing entries that use the MTLS protocol for transport will automatically be considered reliable.

    For reasons of security, using this option only for static routing entries in a LAN is recommended.

To confirm your settings of a static route, click on the button "OK". Click on the button "Cancel" to abort. Should the system reject the information of a static route, first check if the information is complete and there is no typing mistake. Then change the properties of the static route and try again.
