Analog Telephone Adapters - Connect Your Analog Telephone to VoIP
An Analog Telephone Adapter (aka Analog Adapter or ATA) is a device that allows traditional (analog) telephones to be used with voice over IP (VoIP) services. Typically an Analog Adapter will have two or fewer FXS or FXO ports
and two or fewer RJ45 Ethernet ports. FXS ports are used to connect the device to analog
telephones. FXO ports are used to connect the device
to Central Office lines. RJ45 Ethernet ports are used to connect the device to data networks. Generally analog adapters are about the size of two packs of playing cards. Analog Adapters are commonly used for residental VoIP services, connecting remote offices and fax machines.
