Linksys E-Series Setting Up: Advanced How to enable Voice over IP on your network Do I need to configure Voice over IP? VoIP (Voice over Internet Protocol) is a technology for using the Internet as an interface for telephone communications. To use VoIP, you need to get an account with a VoIP service provider. The VoIP service provider typically provides you with a telephone adapter (TA) that connects to your network. If you do not use your network to make phone calls, you don't need to change the default settings. The SIP (Session Initiation Protocol) ALG (Application Layer Gateway) feature allows SIP packets, used by some VOIP service providers, to traverse (go through) your router's firewall. To configure the router for VoIP: Administration > Management 1. Log into the browser-based utility (see "How to open the browser-based utility" on page 21). 2. Click the Administration tab, then click the Management page. 3. If your VoIP service uses SIP, select Enabled next to SIP ALG. - OR - If your VoIP service uses other NAT traversal solutions such as STUN (Session Traversal Utilities for NAT), TURN (Traversal Using Relay NAT), or ICE (Interactive Connectivity Establishment), select Disabled (default). How to configure UPnP What is UPnP? UPnP (Universal Plug and Play) allows devices connected to a network to discover each other and automatically create working configurations. Examples of UPnP-capable devices include web cameras, online gaming applications, and VoIP devices. UPnP is enabled by default. To configure UPnP: Administration > Management 1. Log into the browser-based utility (see "How to open the browser-based utility" on page 21). 2. Click the Administration tab, then click the Management page. 3. To use UPnP, select Enabled (default) next to UPnP. Otherwise, select Disabled. 4. To allow changing router settings while using UPnP, select Enabled (default) next to Allow Users to Configure. Otherwise, select Disabled. 5. To prevent local network users from disabling your Internet connection through UPnP, select Disabled (default) next to Allow Users to Disable Internet Access. Otherwise, select Enabled. How to use a router as an access point How can I use my old router as an access point? If you have a large area to cover with your wireless signal, or if part of your home has weak signals due to interference, you can use your old router to extend the range of your wireless network. This is a complex process, so this procedure assumes that you have some networking knowledge. TIP Check the documentation for your old router. Some brands of routers include either a switch on the outside of the case or a software option to convert it to an access point. If either of these options is available, follow your old router's instructions to convert it to an access point. NOTE You may need to contact your VoIP service provider to determine the type of NAT traversal configuration they use. 30Cisco E1500 Manual
