QoS, or Quality of Service, refers to configuring your network to support high-quality telephone calls. Most customers simply connect their Panasonic TGP550 to their Internet router and start using the service. In some situations, you may improve performance by enabling QoS. It may also be necessary to configure your firewall to allow the Base Unit to have unrestricted communication with the ACN network.
A static IP address is not supported on this device. Your Panasonic phone system requires a network DHCP configuration, which is commonly built into Internet routers. If your business network doesn't require a static IP address, you have a DHCP server.
