Barracuda Phone System

How do I configure my Barracuda Phone System and a third party PBX to allow internal calls between systems?

All Barracuda Phone Systems, Firmware 2.0.x and Later.


When configuring a third party PBX registration to allow internal calling, we must first have a working gateway configured, and be able to place and receive test calls to external numbers. If the system is not live then we can simulate this by adding external test numbers to the Barracuda Phone System for inbound testing.

Route Localization ? We may want calls originating from, or routing to, remote offices to use different DIDs for routing in order to ensure a local call for routes

Different hours of operation ? We may want different hours of operation for each location.

Emergency Services/ E911 ? This is a critical consideration. This concerns ensuring that emergency services are routed to the correct site when called.

Note ? While the Barracuda Phone System does include options for supporting multiple site installations, it is not designed to operate as a multi-tenant system, and does not include any method or option for isolating account information including Account Details, Directory Lists, and CDR data.

Please review Solution #00005725 - What is the Sites Feature, and How do I configure it on my Barracuda Phone System(s)? for general information on sites, and pre-planning requirements for installation.

Define a third party PBX as a Site:

Assuming that we have already configured the third party system to accept/send calls from/to the Barracuda Phone System, defining a working third party PBX system simply requires us to identify it as internal. Defining this site is accomplished in a few steps:

  1. Navigate to Configuration > Sites.

  2. Select Provider/Port from the selection list.

  3. Enter a name which you will recognize in the Site Name field.

  4. Click the button Labelled Define Site.

Once the site exists, we will need to set up site restrictions to allow or deny calls to pass through the gateway. Please reference Solution #00004848 for steps to create any new routes necessary.
