Set up Your Network for VoIP

Before installing Voice-over-IP (VoIP), it is important to verify that there is adequate Internet bandwidth to support it, a properly configured Quality of Service (QoS) router for call quality, and a battery backup to protect you from power outages.

  • Bandwidth: Determine how much bandwidth you need for your VoIP in your network. Your network must have sufficient capacity to carry the VoIP traffic.
  • Router: 8x8 recommends the use of a router with QoS capabilities to prioritize delay-sensitive voice and video traffic. A high-quality router increases your call quality.
  • Quality of Service: QoS can have a significant impact on the audio (and video) quality of your VoIP phone system.
  • Power outage: VoIP fails when the power goes out. A battery backup system and a power-over-Ethernet switch can save you during power failure.
