Installing the 3CX SBC (Session Border Controller) for Windows

Introduction

Required Details

Install and Configure 3CX SBC for Windows

Introduction

The 3CX SBC is deployed to remote offices where there are more than 2 or 3 IP Phones, to direct only their signaling through the 3CX Tunnel and keep the media streams local which reduces the amount of internet bandwidth that local calls between phones use. SBC will bundle all SIP traffic over a single TCP port which simplifies your deployment by reducing firewall configuration. In addition 3CX SBC will add stability & security and allow you to easily manage and provision your IP Phones remotely.

3CX SBC for Windows should be installed on a Windows machine which is not used by users. If you have up to 20 phones with a maximum of 10 BLF keys per device in your remote office you can use 3CX SBC for Raspberry Pi. For more than 20 phones, then it is recommended to use 3CX SBC for Windows or Debian.

Required Details

To configure 3CX SBC you will be asked for some details from your 3CX Phone System as well as a dedicated Windows installation free of any other server service application, such as DNS, DHCP or SQL.

You will need:

  1. The “Password” for your 3CX Phone System Tunnel. You can find by going to your 3CX Management Console, Expand the “Settings” node > “Security” > “3CX Tunnel” tab > “Tunnel Password” field.
