Other VoIP PBX System Setup

Note: Both All Sites and Site Admins can configure SIP trunks.

VoIP PBX systems include those from 3CX, BroadSoft BroadWorks, CallSprout and Jive Voice. This topic will provide information about these systems, but the process is generic and may be applied to other systems.

The process for setting up your VoIP PBX System, is as follows:

1. Configure your PBX System

   Note: These configurations need to be done in your VoIP PBX system. Consult your PBX system documentation for instructions or ask your network administrator for assistance.

   SIP registration technical notes: UNP should be considered as a single user agent (UA) for all SIP registrations. (The same Call-ID is used for multiple addresses-of-record (AORs) registrations.) Single registration is preferred. Using a SIP trunk is recommended over registering individual SIP endpoints.

   1. Create a SIP Trunk and point it to your UNP server.

      3CX customers When you create the SIP trunk, set Country to Generic and Provider to either Asterisk or Generic.

   2. Define extension numbers in your PBX for use as SIP lines in UNP.

      You'll then add a SIP line in UNP to match each extension you want to use.

      • 3CX: Create an outbound rule to define the extensions that can be used with the SIP trunk you created for UNP.
      • BroadWorks: The SIP line extension you enter in UNP must match an extension on the BroadWorks trunk group being used by UNP.
      • CallSprout: The SIP trunk is configured to route numbers that start with 0 to the SIP trunk. Therefore, you don't need to define extensions in CallSprout; just SIP lines in UNP.
      • Jive Voice: Create dial plans > simple dial extensions.
        

2. Create a UNP SIP registration

   Refer to Create a UNP SIP Registration.

3. Adjust the SIP general settings

   Review the Customizing SIP Settings section to see if you need to make adjustment to any of the default SIP settings.
