FXO ports are crucial for connecting your IP PBX system to the traditional PSTN (Public Switched Telephone Network), allowing for seamless integration with existing phone lines. When selecting FXO ports, consider the number of lines you need to connect and whether the system supports your desired call volume. The Grandstream UCM6300 Audio Series offers a range of options, from the UCM6302A with 2 FXO ports, to the UCM6308A with 8 FXO ports, providing scalability for different business sizes. The variety ensures that you can select a product that matches your specific needs.
