There are two different types of analog gateways:

  • FXS Gateways are analog gateways fitted with FXS ports which help you connect legacy telephones and analog phone systems to IP telephony networks.
  • FXO Gateways are analog gateways fitted with FXO ports which help you connect analog telephone lines to your IP-based phone system or help you connect your legacy phone system network to a VoIP network or SIP trunk.

Sangoma Gateways are available in both FXS and FXO varieties with 4 or 8 ports.
