FXO/FXS ports are essential for connecting traditional phone lines and analog devices to your PBX system. The number of ports needed varies based on how integrated your system is with analog lines. For example, the Grandstream UCM6304A with 4 FXO and 4 FXS ports is versatile for mixed environments, while the Grandstream UCM6300A with no FXO/FXS ports suits fully digital setups. A variety of port configurations cater to different infrastructure requirements.
