VoIP Adapter Selection Guide - VoIP Phone Adapters
Generally, a VoIP adapter is used to connect an analog telephone to a voice over IP service provider (VoIP provider) or VoIP PBX. VoIP phone adapters convert the analog
signal of a phone into voice over IP which then uses the Ethernet (digital) connection to send the call to a VoIP provider or VoIP PBX. Device configuration is usually through a web browser on a local computer or voice commands through a connected analog telephone. There are two types of VoIP adapters, the most popular are simply used to connect an analog telephone to a VoIP service provider or VoIP PBX. These VoIP adapters have one or two FXS ports (think station) for connecting analog telephones or fax machines to. This adapter will also have one or two Ethernet ports to connect to the Ethernet network. The other type of VoIP adapter contains FXS ports and one or two FXO ports (think office) for connecting analog telephone lines to. These are useful if you would like to have an analog fail over in case your internet connection drops out. This type of VoIP adapter will also contain one or two Ethernet ports to connect to the Ethernet network.
