If you are setting up external IP extensions, a TalkSwitch VoIP network, or a VoIP
service that doesn’t handle port forwarding, port forwarding is required.
If port forwarding is required, and your router supports uPNP (Universal Plug and
Play), ensure uPNP is enabled. The TalkSwitch system will use uPNP to
automatically set up port forwarding, and the Automatic (uPNP Enabled) link
will appear. No router configuration is required.
If port forwarding is required but your router doesn’t support uPNP, or automatic
port forwarding doesn’t work, the Manual Port Mapping Required link will
appear. You will need to configure the router as described below.
1. Select the IP Configuration page.
2. If required, click the Manual Port Mapping Required link. The Manual Port
Mapping window appears. It lists the packet type, port number, IP address
and protocol of each required port.
3. To access the router configuration:
a) Click the link containing the IP address of the gateway. The default
browser starts, and prompts you for the router’s user name and password.
b) Enter the router’s user name and password. The browser shows a
setup screen.
c) Navigate to the screen used to set up port forwarding. See your
router documentation.
