Installation PortSIP SBC v11.x

❗ Important If your PortSIP PBX is running version 22.x, you must install PortSIP SBC version 11.x in order to use the latest WebRTC application.

Supported Operating Systems

PortSIP SBC supports the following operating systems:

  • Debian: 112.x

  • Ubuntu: 22.04, 24.04

Preparing the Server for Installation

The following tasks must be completed before installing PortSIP SBC.

System Preparation

  • Ensure the system date and time are correctly synchronized.

  • Linux: Perform installation using a user with sudo privileges.

  • Windows: Installation must be performed using the Administrator account.

  • Assign static IP addresses:

    • If the server is located on a LAN, assign a static private IP address.

    • If the server is on a public network, assign both a static public IP and a static private IP.

  • Install all available OS updates and service packs before installation.

  • Do not install PostgreSQL on the PortSIP SBC server.

  • Disable all power-saving options for the system and network adapters (set the system to High Performance mode).

  • Do not install TeamViewer, VPN software, or similar tools on the host machine.

  • The PortSIP SBC must not be installed on a server acting as a DNS or DHCP server.

Firewall and Network Requirements

The following ports must be permitted by the firewall and must not be used by other applications:

  • UDP: 5066, 25000–34999

  • TCP: 5065, 5067, 8883, 10443

Additional requirements:

  • All commands must be executed in the directory:

  • If deploying on a cloud platform (such as AWS or Azure), you must also open these ports in the cloud provider’s firewall / security group.

Prerequisites

This guide assumes that you have already installed the PortSIP PBX by following the guide:

Installation of the PortSIP PBX

Installing PortSIP SBC and PBX on the Same Server

The PortSIP SBC can be deployed on the same server as the PortSIP PBX.

In this configuration:

  • The PBX handles SIP calling directly

  • The SBC provides WebRTC services and enables Microsoft Teams Direct Routing

Example Server Configuration

  • Private IP: 192.168.1.72

  • Public IP: 66.175.221.120

  • Domain: uc.portsip.cc, Resolved to: 66.175.221.120

  • A trusted SSL certificate (not self-signed) is installed for uc.portsip.cc, refer to the guide: Certificates for TLS / HTTPS / WebRTC

Execute the commands below on the PBX server to install the SBC:

Configure the SBC

After installation, follow the guide: Configure PortSIP SBC on the Same Server as PortSIP PBX

Installing PortSIP SBC on a Separate Server

In most deployments, the PortSIP SBC is installed on a separate server from the PBX.

In this architecture:

  • The SBC acts as the front-end edge component

  • The PBX remains transparent to end users

Example Server Configuration

  • PBX Server (Private IP): 192.168.1.72

  • SBC Server (Private IP): 192.168.1.73

  • SBC Server (Public IP): 66.175.221.120

Domain Configuration

Install PortSIP SBC on Linux (Separate Server)

Step 1: Initialize the Environment

On the dedicated server used to install the PortSIP SBC, execute the following commands:

Step 2: Install the Docker-Compose Environment

If prompted with:

Enter Y and press Enter.

Step 3: Create and Run the SBC Docker Instance

Configure the SBC

After installation, follow the guide: Configure PortSIP SBC on a Separate Server
