FXO ports are crucial for connecting your IP PBX to the traditional Public Switched Telephone Network (PSTN). When choosing FXO ports, consider the number of lines you need to connect and future scalability. Options range from no FXO ports to systems with several, such as the Grandstream UCM6308 with 8 FXO ports. A higher number of ports can support more PSTN lines, offering greater flexibility and redundancy. The Grandstream UCM6304 and Grandstream UCM6304A also offer multiple FXO ports, making them excellent choices for businesses needing robust PSTN connectivity.
