SIP Static Routing

Please gather and configure here your list of static routing entries used for outgoing connections. An introduction describing the creation of static routing entries for Microsoft® Lync® Server can be found at Creating a Static Route between estos UCServer and Microsoft® Lync® Server using TLS/MTLS.

List of all static routes

• Use static routes
  Activate or deactivate the functionality of the static routes included in your list here. If you deactivate "use static routes", all your static routes are deactivated and you can't carry out any adaptations in your existing configuration.

• Partner Domain configuration
  Shows the list of the registered and configured static routes. Every line in the list represents a static route with individual settings. The following properties of a static route are displayed.

  • Activate
    Activates, or deactivates, the static routing entry. You can make this setting directly. Click the checkbox to enable or disable the static routing entry. Additional information regarding this can be found under Static Routing Entry Properties.

  • Trustworthy
    Indicates if the static routing entry has been categorized as trustworthy. You can make this setting directly. Click the checkbox to enable or disable its function. Additional information can be found under Static Routing Entry Properties.

  • Domain
    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. Additional information can be found under Static Routing Properties.

  • Access server
    Displays the server's IP address used for accessing the domain. This value may also be a symbolic name, which will be converted into an IP address as part of operations. Additional information can be found under Static Routing Properties.

  • Port
    Displays the port used by 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. Additional information can be found under Static Routing Properties.

  • Log
    Displays the transport protocol for the selected access server. Various protocols are available for static routing. Information regarding transport protocol settings and additional information can be found under Static Routing Properties.

  • Linked on
    Displays the selected IP address, if the system has been bound to an IP address. Additional information can be found under Static Routing Properties.

Configuring static routes

You can modify your static routing list. Click the Add... button to add another entry to the static routing list. Click the Delete button to remove one or more static routing entries from the list. Click the Properties... button to display the static routing properties and change them, if necessary.

• Add...
  Click this button to add additional static routing entries to the list. A new window will be displayed, from which you will be able to change the property settings for the new static routing entry. Afterwards, click Ok to add the new entry to the list. Click Cancel to reject the new static routing entry.

• Remove
  Click on this button to remove static routes from your list. You are only able to carry out the removal, if at least one static route is marked in the list. Afterwards you are asked to confirm the removal. Click on the button "OK" to confirm. Click on the button "Cancel" to abort.

• Properties...
  Click on this button to get the properties and details of a static route displayed in another window. You need to have marked exactly one static route on the list to do so.

Adapt the properties of the static routes

• 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.

• Network interface for incoming connections
  Select a network interface for incoming server connections. The network interface is added to the list of Network interfaces for incoming connections by finishing the configuration.
  

  • IP interface
    Select the network interface to be used with connections to the UCServer.
  • Port
    Please specify the port number to be used with connections to the UCServer.

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.
