3 Design your network for voice Get to know your network Internet Base Connection Modem Firewall Router Switch Devices Wireless access point Your ISP provides your broadband connection through a DSL, cable, wireless (Wi-Max/ Clearwire), or other type of connection. A broadband modem converts the base Internet connection into an Ethernet TCP/ IP connection, so your equipment can feed standard Internet language to the network. A firewall helps prevent outside intruders from accessing your internal network. A router enables multiple devices in your network to share your Internet connection. Use a switch to plug multiple devices into the router at once, (similar to a power strip). Provide wifi access for your office by connecting a wireless access point to your switch. Connect computers, network printers, IP phones, servers, or other networkenabled hardware to your network. Note: A typical home or small-office multi-function router provides firewall, routing, wifi, and switch capabilities all in one box. Larger offices tend to use separate devices to perform each function. RingCentral Office 3

4 Optimize your network for voice More speed means better quality, so get the fastest Internet connection that fits your budget. Allocate 64kbps upload and download for each call in addition to data traffic for your PCs and use properly configured QoS-enabled routers and switches. (If choosing between the two, purchase a QoS enabled router over QoS-enabled switches.) Purchase a QoS-enabled router if you haven t already. We recommend and document the configuration for several QoScapable routers, both with and without included WiFi access points. See our separate document for specific recommended models and how to configure them. Configure your QoS-enabled router Configure your QoS-enabled router to support QoS according to the manufacturer s included documentation. Alternately, if you purchase a RingCentral recommended router, you can configure it according to our documentation. Use the following to configure your router if not purchasing a RingCentral-recommended model: ToS bits: 101 (5) UDP port ranges: , , If you use your modem to perform routing functions, disable the router functions of your modem and use a separate QoSenabled router. Designing your network Larger offices may require additional work to support voice. There are two approaches: Shared networks Design your network to support QoS, so that data and voice can share a single network. You ll need to be sure you have enough bandwidth available to meet all your voice and data needs. You may need to combine multiple broadband or wireless broadband connections using a load-balancing router. Separate networks Keep data from sharing voice bandwidth by separating voice and data networks. You don t need QoS-enabled routers and switches to deploy a separate networks approach for larger offices commonly available gear will suffice. Shared network approach Modem Router Switch PCs, phones, and other devices Use a load-balancing router to split load over multiple modems. The router MUST be QoS-enabled and configured. Switches should be QoS-enabled. Use multiple switches if necessary (switches RingCentral Office 4

6 Addendum: Wireless Broadband support Configure wireless broadband for small offices. Plug a recommended router into the wireless broadband modem, and configure it as documented. Do not use a modem as a router. Use a RingCentral recommended switch if you need more ports than the router provides. Depending on the speed, a single modem will suffice for a small office with less than 8 phones and light Internet use. Modem Router Switch Devices Connect a router to the modem. Do not connect a switch or any other device to the modem. avoid using power cords for the phones RingCentral Office 6

7 Configure wireless broadband for larger offices Larger offices may require multiple broadband modems to distribute the network load. Separate phones into their own network using one or more modems or connect phones and PCs together in the same network to one or more modems, but use a QoS-enabled router to prioritize voice traffic. Shared network approach Modem Router Switch PCs, phones, and other devices Use a load-balancing router to split load over multiple modems. The router MUST be QoS-enabled and configured. Switches should be QoS-enabled.
