What are the types of VoIP adapters?



Types of VoIP Adapters

Single FXS – As the name implies, these adapters come with a single FXS port that can connect one instrument(telephone) to the VoIP service.
Dual FXS – These are slightly more expensive adapters that offer dual FXS ports for users who want to connect to two instruments(telephones) or one instrument and a fax machine.
FXS/FXO – These adapters include both FXS and FXO ports to connect a single telephone and a single POTS line. These combination adapters are typically used to provide fail-over or used in case of emergencies.
Now you might be thinking, “What if I need to connect more than two telephones or POTS lines? ”

Businesses that use more than one line will require VoIP gateway. VoIP gateways perform the same essential functions as a VoIP adapter but are built to scale (up to 48 ports).
