How to enable Voice over IP on your
network
For
ALL
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 25) .
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) .
noTE
You may need to contact your VoIP service provider to determine
the type of NAT traversal configuration they use .
