VOIP Routers

There are hundreds of different models of routers available, this is list of routers that may be of interest to VOIP users.

Small Routers with Multiple WAN Interfaces

Having multiple connections to the Internet from different providers can be a challenging configuration puzzle. Some routers are designed to make this easy for simple installations.
  • Astrocom Ecessa ClariLink - multiple WAN interfaces with load balancing and automatic call failover
  • DrayTek multi-WAN routers have special VOIP prioritization features to insure voice goes out first.
  • Linksys RV082 10/100 8-Port VPN Router with 2 WAN interfaces
  • SmartShare Systems FairRouter Dynamic QoS router that automatically detects VoIP traffic (incl. Skype) and ensures high sound quality.
  • SmartNode VoIP routers from PATTON Electronics are industry-renowned for set-it-forget-it reliability. And they come with free support! SmartNode integrates IP and TDM communications for Enterprise and Carrier access networks, offering VoIP gateways combined with IP access routing, WAN transmission, and VoIP border router functionality. SmartNode scales from 1 to 2,048 VoIP or fax calls with various telephony interfaces including analog FXS/FXO and digital ISDN BRI, PRI, DS3 and STM-1.


Small Routers with QOS and built-in VOIP ports

Small NAT Routers with SIP Proxy

Do-it-yourself Linux or BSD Routers with QOS

  • Mesh Router Linux Distribution
    • wired and wireless support
  • Monowall (FreeBSD)
    • just boot and run
    • web based configuration
    • includes real-time traffic graphing
    • magic shaper wizard aids in setting up traffic shaper rules
    • configs stored in convenient XML format
    • PC version runs on slow old PC with dual NICs. Boots from CD and stored setups on floppy. No HD required.
    • Embedded versions run on Soekris Engineering and PCEngines small format boards. Boot from and store setups to CF card.
    • includes VPN server and client capability.
    • may be configured as router & wifi access point.
    • can enforce VPN over wifi
  • pfSense (FreeBSD)
    • fork of M0n0wall
    • pfSense has very nice QoS for VoIP and traffic shaping, different from m0n0wall.
    • embedded version runs also on generic PC hardware, but unlike m0n0wall the output is directed to the serial port in this case. Therefore, for the embedded version you need a null-modem cable to connect from the serial port of your PC to the serial port of the router. Under Windows XP you can use HyperTerminal with settings for the serial connection of 9600 bits per second, 8 data bits, no parity, 1 stop bit and flow control set to hardware to see the output when the router boots. On linux you can use minicom as your terminal emulator.

  • ZeroShell - A live CD and CompactFlash router for embedded devices with web interface
    • QoS and traffic shaping capabilities
    • QoS classifier that using Layer 7 filters allows to classify VoIP protocols such as SIP, H323, Skype and MSN Messenger
    • VPN Lan tp Lan and Host to Lan
    • Captive Portal
    • DNS
    • DHCP
    • Bridge and VLAN
    • etc.


Bandwidth Shapers

StreamEngine-based product

StreamEngine is a technology by Ubicom, that is incorporated in other vendor's network devices. Lets you prioritize your WAN's outbound traffic based on a proprietary protocol. Few adjustements are needed/possible.
