When selecting a Dual FXS product, the number of FXS ports is crucial as it determines the number of analog devices you can connect. Most Dual FXS products come with 2 FXS ports, ideal for small setups involving two analog phones or a combination of a phone and a fax machine. For instance, the Grandstream HT802 and the Poly ATA 402 both provide 2 FXS ports, offering flexibility for various configurations. These options ensure you have the necessary connections for your specific needs in a VoIP ATA.
