A VoIP router combines the functions of an Analog Telephone Adapter (ATA) and a high-speed internet router. Its features are similar to a cable or DSL router, except for an additional ATA port that connects to the telephone. It typically has a wide-area network (WAN) port for connecting to a high-speed cable or DSL modem, one or two ATA ports for linking up analog telephones, and two to four LAN ports for connecting to a PC network.
Connecting a VoIP router allows the analog telephone to function as a VoIP phone without blocking Internet access to the computer. It also allows the use of a software-based phone on the computer for making VoIP calls. It helps save on space, cable connections, and call costs, as it eliminates the need for individual ATAs.
Types of VoIP Routers
Kinds of VoIP Routers include the following:
Service provider-specific VoIP router
This VoIP router is designed to work with a particular VoIP service provider. It usually comes with bundled software to access various features and provide an interface for operation.
Generic VoIP router
A generic VoIP router can work with any VoIP service provider. It can be easily configured through a web browser. It provides flexibility and convenience, as it can change VoIP providers without changing the hardware.
Choosing VoIP Routers (Buying tips)
Security: Look for a VoIP router that comes with a firewall to get various degrees of internet privacy and security depending on your preference.
Ports: Choose a VoIP router with multiple ports for connecting to multiple computers of VoIP devices.
