Yeastar PBX systems are among the advanced solutions widely popular in companies and institutions due to their ability to manage internal and external communications with high efficiency and reasonable cost.
If you’re considering installing a PBX system for your office or company, this comprehensive guide will walk you through the installation process step by step in an easy and organized manner. We’ll cover all the details, from planning to operation, focusing on best practices to ensure a successful process.
Part One: Planning for PBX Installation
Before starting the installation, it’s essential to create a clear plan that meets your PBX needs. Begin by determining the number of required internal and external lines. For example, if your company has 20 employees, you may need a system that supports at least 20 internal lines, along with an appropriate number of external lines based on your daily call volume—perhaps 2-4 external lines for small businesses.
Next, select a suitable location for the Yeastar PBX unit. It’s preferable to choose a well-ventilated spot, away from humidity and excessive heat, and easily accessible for maintenance. Ensure there’s a nearby and stable power source, and consider using an uninterruptible power supply (UPS) to guarantee continuous operation during power outages.
Part Two: Required Tools and Equipment
You’ll need a set of basic tools and equipment for the installation, including:
If you plan to integrate the PBX with VoIP technology, ensure you have a high-quality router and Cat5e or higher Ethernet cables. This step is optional but adds significant flexibility, especially if you intend to use internet-based calling.

Part Three: PBX Installation Steps
1. Inspecting Components
Upon receiving the PBX unit, carefully inspect all included components. Verify the presence of the main unit, line cards (if using analog lines), power supply, and any additional accessories like compatible desk phones. If you notice any shortages or damage, contact the supplier immediately.
2. Installing the Main Unit
Secure the PBX in the pre-selected location. If the device comes with a wall mount or rack, use it to firmly install the unit. Ensure it’s tightly fixed to avoid vibrations that could affect performance or cause connection disruptions.
3. Connecting External Lines
Start by connecting the external telephone lines to the PBX input ports, typically labeled "Line In" or "PSTN." Use RJ11 connectors and carefully attach each external line, ensuring the wires are secure and there are no loose connections that could weaken the signal.
4. Connecting Internal Lines
Next, connect the internal lines that will link desk phones to the Yeastar PBX unit. You can extend cables from the PBX to each office or internal connection point using suitable telephone wires. Number each internal line (e.g., 101, 102) to simplify programming and management later.
5. Connecting the Power Source
Connect the PBX to the power source using the provided power adapter. Monitor the operation indicators on the main unit to confirm the device is functioning correctly. If the indicators don’t light up, check the electrical connections or replace the adapter if necessary.
Part Four: Programming the PBX
Once the physical connections are complete, it’s time to program the PBX to meet your specific needs. You can access the programming interface via a computer connected to the PBX over the network or through a dedicated desk phone if the system supports this feature (refer to the manual for confirmation).
1. Assigning Internal Numbers
Assign an internal number to each phone connected to the PBX. For instance, set 101 for the first office, 102 for the second, and so on. Be sure to document these numbers for easier management and maintenance.
2. Setting Up External Call Routing
Configure the external call routing rules based on your needs. You can designate a specific internal line (e.g., the reception desk) to directly receive incoming calls or activate an Interactive Voice Response (IVR) system if supported by your Yeastar PBX model, allowing callers to select their destination via a voice menu.
3. Activating Additional Features
Take advantage of advanced Yeastar PBX features like call recording, voicemail, and internet calling if using VoIP technology. These options can be easily configured through the programming interface, tailored to your team’s requirements.
Part Five: Testing the System
After installation and programming, test the PBX to ensure everything works as expected. Begin by making an external call from an internal line to verify sound quality, then check the reception of incoming calls on the assigned lines. Also, confirm that features like call transferring between lines, call waiting, and the IVR system (if applicable) operate smoothly.
