Getting To Know VoIP Devices
The VoIP market is populated by VoIP devices. There are various types out there and vary in model and sizes to be applied for different services and solutions. You will notice one common, that is most devices come with single or multiple ports so a user can plug telephone lines and Ethernet cable.
The ports are known as...
- RJ-11 or FXS port - where you plug your corded or cordless, fax telephones and a PBX (Private Branch Exchange). In telephony the term FXS (Foreign eXchange Station) is used where you connect a telephone to back side of your VoIP device such as ATA and gateway.
- FXO (Foreign eXchange Office) port is where you plug a PSTN (Public Switched Telephone Network) line to your VoIP device meaning the line that comes from your phone company.
- RJ-45 port - this is where you plug your Ethernet cable to your Internet modem/router.
