Critically important information for all devices.

The routers above are recommended because they have:

  • A long track record of success with many customers that own these devices that we have worked with extensively.
  • Bandwidth Management/Rate Control, which is an important feature to have when using a VoIP system.  It's effective at ensuring excellent call quality and effective at resolving call quality problems in many cases.
  • Some necessary configuration changes, as is the case with all routers, but they work well after the changes are made.

Feature comparisons are based on the following models:

  1. AirStation N600 DD-WRT Router WZR-600DHP
  2. ZyXEL USG20W
  3. SonicWall TZ215
  4. Cisco Meraki Z1 Cloud Managed Router
