Router & Firewall Guide

VoIP depends on the strength of the local network, and the backbone of the network is its router/firewall. There are many choices in choosing a router/firewall. Some guidelines are:

  • Avoid home-grade routers - always use business class firewalls. Linksys routers will work if a solution is needed quickly, but lack features such as the ability to establish QoS and customize the firewall rules.
  • Avoid Netgear, D-LInk, and Asus routers. There are consistent issues with these routers, and replacing them usually fixes the problem.
  • Cyberoam, Sophos, SonicWall, and Ubiquiti Edgerouter series firewalls are recommended. These have proven to be consistent, and information about these routers can be accessed here.
  • While the Cisco RV series is recommended below, only newer models (RV120+) fall under that. Older models like the RV042 are not recommended.
Not Recommended Recommended
Netgear Sonic Wall
D-Link Sophos
TP-Link CyberRoam
Linksys Ubiquiti Edgerouter
Cisco RV042 Cisco Meraki

Typically, routers/firewalls purchased from general office supply stores do not have the ability to establish best practices for setting up the network. Stores specializing in electronics carry a better assortment of business grade routers/firewalls. It's essential to have the right device in place for a quality VoIP solution.
