Analog telephony, also known as Plain Old Telephone Service (POTS), is the service the local phone company typically delivers to your home.
What is Fxo in router?

What does a VoIP Gateway do?
What is a VoIP gateway? A VoIP gateway is a piece of hardware with the standard purpose of converting TDM telephony traffic from the PSTN into digital packets IP packets for transport over an IP network (such as your LAN).
What causes FXS?
FXS is caused by changes in a gene that scientists called FMR1 gene when it was first discovered. The FMR1 gene usually makes a protein called FMRP. FMRP is needed for brain development. People who have FXS do not make this protein.
What is analog gateway?
Analog VoIP gateways are small stand-alone appliances which allow you to convert voice media between FXO and FXS connections and VoIP connections. They are the most cost-effective solution for businesses with a legacy phone system infrastructure which want to connect to a VoIP network, such as a SIP trunk.
What is PSTN line?
PSTN stands for Public Switched Telephone Network, or the traditional circuit-switched telephone network. This is the system that has been in general use since the late 1800s. The phones themselves are known by several names, such as PSTN, landlines, Plain Old Telephone Service (POTS), or fixed-line telephones.

A network device that converts voice and fax calls, in real time, between the public switched telephone network (PSTN) and an IP network. The primary functions of a VoIP gateway include voice and fax compression/decompression, packetization, call routing, and control signaling.
What do FXS and FXO mean and how do they work?
If you want to use analog telephone lines with your phone system, you need one FXO port per line. To connect analog phone lines to an IP phone system you need an FXO gateway. This allows you to connect the FXS port to the FXO port of the gateway, which then translates the analog phone line to a VoIP call.
Which is an example of an FXO port?
FXO is the port used by analog devices, example: FXO port of an analog phone, modem, fax (these devices are often called FXO devices), FXO port of an analog telephone exchange used to connect lines. FXO media gateway (media gateway with FXO port) is necessary to connect analog line to VoIP PBX.
How is the FXO interface connected to the PBX?
In analog telephony, FXO interface of the analog device is connected to the FXS interface of the analog line provided by the telephone company (the wall jack). FXS interface (analog telephony line) is connected to the FXO gateway, which, in its turn, is connected to the IP PBX.
What’s the difference between FXO and FXS Wildix?
FXS interface provides telephony services and supplies battery power, provides dial tone and generates ringing voltage. FXO interface receives telephony services and generates off-hook and on-hook indications at the FXS end of the telephone circuit.
