FusionPBX

Set up ProSBC between an ITSP SIP trunk and a FusionPBX server, covering trunk creation, extensions and remote worker access.

Introduction

This article describes how to set up a Telcobridges ProSBC for interworking between an ITSP’s SIP Trunk, or remote client access for a FusionPBX server.

NOTE: TheSIP Trunk uses G.711 in this test. There is no transcoding available.

Prerequisites

  • ProSBC devices must be installed as described with respect to release 3.0.x/3.1.x. Release 3.0.x is not supported for TCP connections installation guides.

  • FusionPBX. For additional information about FusionPBX, visit FusionPBX offical web site.

Example Environments for SIP Trunking with FusionPBX
