This article describes how to set up your router so that it is best configured for your Voice Services.

  1. Make sure that your internet service provider meets the Minimum Network & ISP Requirements and VoIP Bandwidth Requirements.
  2. Make sure that you are using one of the Recommended LAN Configurations.
  3. Make sure the router meets and is configured to the Router/Gateway Requirements
    • Preferably select a router from the Recommended Routers List. These devices meet all of the Router/Gateway Requirements and also have a robust Bandwidth Management (BWM) system that effectively aids in preventing call and fax quality issues sometimes caused by network congestion.  These devices can help to guarantee high-quality service.
    • You may also have success with any router listed as serviceable in the Full Router & Gateway List By Make/Model list.  These devices meet all of the Router/Gateway Requirements, but either do not have Bandwidth Management (BWM) or lack an effective BWM system, causing the router to be unable to prevent call and fax quality issues sometimes caused by network congestion.  These devices will work well in most circumstances.
    • If your router is not in the Full Router & Gateway List By Make/Model list, or if it is listed as something other than compatible or serviceable for the Router/Gateway Compatibility Status Type, please call our Voice Support team so that a voice hardware specialist can check the router for you.
  4. You will connect your VoIP phones to the router ports or, more likely, to a Recommended Switch that connects them to the router.
