SIP Server

Configuration of network interfaces to be used for incoming connections.

• Use SIP Server
  Activates or deactivates the SIP services. The SIP server must have been activated and the corresponding network interfaces configured in order to be able to use the SIP Proxy, Open Federation and Static routing federation services. If you deactivate the SIP server, you cannot carry out other settings to SIP based services and network interfaces.

• Certificate
  To use the secured network protocols TLS and MTLS, you need a Server certificate. This has to be signed by a certification authority. Click on the button "Certificate..." to open the window for the certificate selection. Select the suitable certificate and afterwards confirm the information with "OK". Information about the selected server certificate is also shown.

• Use SIP registrar
  Activates, or deactivates the usage of the SIP Registrar service. SIP Registrar allows SIP user agents to be registered. SIP messages will only be accepted from authorized user agents when the SIP Registrar has been activated. This service can only be activated if the SIP Server has been activated.

• Use other public address
  Activates or deactivates the use of the public address. If it's necessary that your server is connected with the internet via NAT-Routing (Network address translation) then activate this function.

  • Port / IP
    Shows the port number and the IP address which should be used as a public address. The port number can range from 0 to 65535. Certain applications use port numbers which are specially assigned and are generally known. They usually lie between 0 and 1023. Therefore, it is best to select a port number between 1024 and 65535. If you enter no port number or if you do not know the port number of your access server, try to enter the standard port number of 5060. If you have activated the Use Public Address option, you should also enter the appropriate IP address. You can enter this value manually. If you do not know it then click the Determine IP button. The appropriate IP address will then be determined and the entry will be automatically set.

  • Detect IP
    Click this button if the system should automatically determine the IP address when the Use Public Address feature has been enabled.

Network interfaces

List of the network interfaces

Lists the network interfaces which are used for incoming connections. Every network interface has certain properties and additional information which is summarised in the index. The following properties of a network interface are displayed:

• Activate
  Activates or deactivates the network interface. You can carry out this setting directly. Click on the checkbox to activate the network interface. Click again on the checkbox to deactivate the network interface. If the network interface is deactivated, the checkbox is empty.

• IP
  Displays the network interface's IP address. Together with the specified port number, it will uniquely identify the interface. Select the line and click the Properties... button to change the network interface's IP address.

• Port
  Displays the network interface's port number. The port number and the IP address will uniquely identify the interface. Select the line and click the Properties... button to change the network interface's port number.

• Log
  Displays the transport protocol of the network interface. Different protocols for network interfaces can be selected.
  - UDP (User Datagram Protokoll)
  - TCP (Transmission Control Protocol)
  - TLS (Transport Layer Security)
  - MTLS (Mutual Transport Layer Security)

  Select the line and click the Properties... button to change the protocol type for the network interface. You will also need a server certificate for the use of secured protocol over secured network interfaces. Additional information regarding certificate specifications can be found under Server Certificates.

• Status
  Displays the status of the network interface. You are not able to edit this design.

Configuration of network interfaces

You can configure the list of your network interfaces. Click the Add... button to add additional network interfaces to the list. Click the Delete button to remove one or more network interfaces from your list. Click the Properties... button to display the network interface's properties and adjust them, if necessary.

• Add...
  Click this button to add an additional network interface to the list. A new window will be opened, where the network interface's Properties can be set. Additional information about the network interface's properties and how you can determine them can be found in the Network Interface List section.

• Remove
  Click on this button to remove network interfaces from your list. You can only do this if at least one network interface was marked on the list. Afterwards, you are asked to confirm the removal of the marked network interfaces. Click on the button "OK" to confirm the removal. Click on the button "Cancel" to stop this action.

• Properties...
  Click on this button to display the properties and details of a network interface. You must select only one network interface on the list. You can also adjust the network interface's properties. Additional information about the network interface's properties and how they can be adjusted can be found in the Network Interface List section.
