VoIP Routers

VoIP router specifications can fill up a notebook. A VoIP router is a complex piece of equipment used to forward data packets from one network to another. Internal routing tables tell the VoIP router how to forward the data packets. VoIP routers may be used in business settings to separate the Local Area Networks (LANs) into subnets for load-balancing purposes and to filter traffic for security purposes. A VoIP router may also be used in the home with an Internet connection in order to route traffic to and from a PC.

Some VoIP routers are built as dual router-gateways. A VoIP gateway serves to translate analog voice into digital data packets between VoIP networks and traditional PSTN / POTS networks. The combination of a VoIP router and a gateway in one box can mean that applications such as firewalls can be optimized in one area.

Three of the most important features to look for in any VoIP router are the presence of a firewall, Quality of Service (QoS) deployment and other security features. A VoIP router also needs to accept typical phone service features such as call waiting, caller ID and call forwarding. A firewall is necessary to prevent many hacker attacks that are associated with any Internet device. Denial of Service (Dos) attacks can be particularly difficult when sending voice over an IP address that is being flooded by such an attack.


If a VoIP router, however, has a QoS system already in place, this will help matters immensely. A VoIP Qos system typically gives priority to data packets over other kinds of traffic such as downloading files to a PC or surfing the Internet. Downloading and surfing may be a bit slower because of QoS but usually this is not noticeable. If no QoS is on the router, however, voice can be degraded to the point of being of very unacceptable quality. Some routers' QoS systems will reserve part of the Internet bandwidth just for voice data transmission while a call is active and then release the bandwidth after the call has completed.

Besides a firewall, other security features to look for in a router include intrusion prevention system (IPS), Virtual Private Network (VPN) and encryption of data. VoIP routers, such as those made by Cisco, include three core security features of Secure Connectivity, Threat Defense, and Trust and Identity. Secure connectivity involves the use of VPN to assure quality and reliability. Threat defense involves responding and defending against network attacks using a secure firewall. Trust and identity means authorization, authenticationand accounting of data by use of public key infrastructure and data encryption-decryption.


VoIP routers are many in the marketplace now days. The first decision to make is whether to buy a router for home or business use. Once this is decided, then it is time to check out your own needs or that of your organization. Then it is time to check out the specifications from the different VoIP router manufacturers to get the device that will work best for your unique situation.
