See this document for router and firewall requirements.

Fewer than 3 phones:

Internet:

Shared with PCs: 10 Mbps / 3 Mbps

 Notes:

In offices with more than 10 phones, a business-grade internet connection is a must. In most areas, Cable or Fiber is preferable to DSL.

Connecting PCs through phones in passthrough, or a shared LAN is not recommended.

Internet and phones may warrant an Uninterruptable Power Supply, if power loss would be an issue.

Internet connection should be tested to demonstrate the following:

 Consistent <100ms ping times to portal.nwvox.com

 Less than 5% packet loss on a ping test of 100 or more packets.

 Traceroute should not show more than one gateway device present on the network.

 Phones absolutely can not be behind a firewall, especially SonicWall devices.
