To install the 3CX VoIP server on a Windows Server, it's important to follow specific system requirements and steps. This guide will walk you through the process from preparations to final configuration, including connecting to Internetports SIP trunk.

System Requirements and Prerequisites

  1. Step 1: Check System Requirements

    To run 3CX, you need a Windows Server that meets the minimum requirements for RAM, CPU, and storage space. Ensure your operating system is compatible with the version of 3CX you are installing.

  2. Step 2: Open Necessary Ports

    To ensure communication between 3CX and your phone systems, make sure the following ports are open: UDP/TCP 5060 for SIP, TCP 5090 for WebRTC, as well as other relevant ports depending on your configuration.

Download 3CX Installation File

    Go to the official 3CX website and navigate to the download page to get the installation file. Make sure you download the correct version for your Windows Server.

Run Installation Wizard and Select License

  1. Step 4: Start the Installer

    Run the downloaded installation file. Follow the instructions in the wizard to install 3CX on your server.

  2. Step 5: Choose License Model

    Select an appropriate license model for your needs. You can choose from different options depending on the number of calls and users you plan to have.

Basic Configuration: Country, Prefix, Codec

  1. Step 6: Configure Basic Settings

    Once installation is complete, log into the 3CX administration interface. Here you configure basic settings such as country, internal number prefix, and default codec.

Connect Internetport SIP Trunk

  1. Step 7: Retrieve SIP Credentials from Customer Portal

    Go to Customer Portal, navigate to Services, and retrieve your SIP credentials for the SIP trunk you want to connect.

    Use the retrieved credentials to configure a new SIP trunk in 3CX. Enter the IP address, ports, and authentication details obtained from the Customer Portal.

Verify System Functionality

  1. Step 9: Test Connection to SIP Trunk

    Once configuration is complete, test the connection by making a test call through the newly created SIP trunk. Ensure that audio works correctly and there are no issues with connectivity.

Common Issues

  • Error message about insufficient memory: Check that your server has enough RAM and storage space for the 3CX installation.
