Sipelia™ Communications Management

To connect to SIP servers other than Sipelia™ Server, you can add a SIP trunk in Config Tool, and then define applicable dial plan rules to make and receive calls between the SIP servers.

What you should know

  • SIP trunks work together with dial plans. For example, to connect Sipelia™ Server to another SIP server (SIP Server A) through a SIP trunk, you must define dial plan rules that instruct Sipelia™ Server about which calls to reroute through the trunk and on towards the new SIP extension destinations that are registered to SIP Server A. Furthermore, if you want proper two-way communication between Sipelia™ Server and SIP Server A, both SIP servers need to be configured accordingly.
  • When Sipelia™ Server is connected to another SIP server (SIP Server A) through a SIP trunk, SIP Server A can request authentication from the Sipelia™ Server. The Sipelia™ Server must confirm its identity using the credentials configured in SIP trunking > Server credentials.
  • When authentication is enabled between trunks, you must ensure that the caller extension is configured as an intercom belonging to another Server. Otherwise, the Sipelia™ Server will revert to its default authentication setting.


  1. Log on to Security Center with Config Tool.
  2. Select the Sipelia™ role, and then click the SIP trunking tab.
  3. Click Add SIP trunk.
  4. In the Name field, enter a descriptive name for your SIP trunk.
    The name of the SIP trunk must be unique because it will be used in the dial plan rules involving this SIP trunk.
    You might name the SIP trunk TrunkSIPServerA for SIP Server A.
  5. Complete the following fields:
    IP address
    The IP address of the SIP server that you want to connect Synergis™ Server to.
    SIP port
    The port used by the SIP trunk to communicate with the Synergis™ Server. Because SIP trunks are SIP servers, the default value is 5060.
    A Sipelia™ Server IP address might be: with port 5060.
  6. To authenticate a request, set the authentication option to ON and enter a username and password that will be used to validate the identity of the other SIP server (SIP Server A).
  7. Click Add, and then click Apply.


The SIP trunk TrunkSIPServerA has been added. The LED in the first column indicates the state of the trunk: green for online and red for offline.

IMPORTANT: The SIP extension configured for an intercom entity in Security Center is the unique identifier of this entity. For intercoms connected to an Intercom Exchange Server connected with a trunk to Sipelia™, this SIP extension must be used to call the intercom. This extension must also be the identifier used by the intercom to call Sipelia™ clients. The Dial Plan rules must be properly configured for these extensions to match.

After you finish

To call extensions registered on TrunkSIPServerA, define the applicable dial plan rules.
