Known Issues

  1. The Netgear DGND3700 comes with SIP-ALG enabled by default, it varies by specific model and firmware revision if this can be disabled at all.
  2. It will need to be determined by you or your IT if your particular model and revision is able to have SIP-ALG turned off. Using a Netgear DGND3700 with SIP-ALG is not recommended and will cause frequent issues with your phone system.
  3. DNS relay/proxy is enabled by default, which causes DNS lookup timeouts on Polycom phones, this is also known as URL Calling Disabled.  That setting needs to be disabled to prevent intermittent or frequent registration failures. 
  4. WAN Pings is disabled by default, which is an optional setting that is needed to allow the router to respond to our Call Quality Monitoring and Troubleshooting Ping Server. This will make troubleshooting any potential issues more difficult to pinpoint.


  1. The DGND3700 is a gateway (modem/router) equivalent of the Netgear WNDR3700.  It requires the same changes as most other Netgear routers to make it compatible with Intermedia service.
  2. See the article Instructions for Netgear Routers.
