Note: SIP ALG, if supported by the firewall/router, should be Disabled at both locations
Configuring the router
The Router Port Forwarding area of the IP Configuration page displays the type of
gateway device (i.e. the type of router), the IP address of the gateway (i.e.
router), and whether router configuration is required.
A router is a gateway between the local area network and the Internet. Most
routers have a firewall to block unwanted data from the Internet. For voice data
to reach the TalkSwitch system through the firewall, port forwarding is required.
Port forwarding allows the router to map ports to the IP addresses of the
TalkSwitch units. Valid Internet data will use the ports to go through the firewall
to the TalkSwitch units.
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 in the talkswitch system configuration.
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.
d) Set up port forwarding using the information from the Manual Port
Mapping window. See your router documentation for instructions on how
to map ports. For information on configuring routers and mapping ports,
visit http://www.portforward.com/.
4. To check the status of each port through the firewall, click Check Firewall.
The Firewall Test window appears.
5. Select the services you want to check.
6. Click Test Ports. The system will check the ports for the selected services.
Configuring the router manually
If you cannot access the router configuration through the IP Configuration
page, configure the router manually.
1. Open the router configuration and navigate to the screen used to set up
port forwarding. See your router documentation.
2. Map port 5060 (Type: UDP) to the TalkSwitch unit acting as local proxy.
Port 5060 is the default port for forwarding SIP signaling data to the
TalkSwitch system (typically unit 1).
If required, you can map a different port. In this case, connect to the unit
using TalkSwitch software, select Troubleshooting --> VoIP Settings and
enter the port in the SIP signalling port field.
3. Map the following ports (Type: UDP) to the TalkSwitch units. These RTP
ports forward voice traffic to the TalkSwitch system by default.
If required, you can map different ports. In this case enter the first port in
the Starting RTP port box of the VoIP Settings window.

4. If you are setting up external IP extensions, map port 69 (Type: UDP) to
the TalkSwitch unit acting as local proxy. Port 69 allows the TalkSwitch
system to configure external IP extensions.
5. If you are setting up TalkSwitch IP phones as external IP extensions, map
port 8484 (Type: TCP) to the TalkSwitch unit acting as local proxy. Port
8484 allows the TalkSwitch system to configure TalkSwitch IP phones as
external IP extensions.
6. Map ports 9393, 8485 and 8486 (Type: TCP) to the TalkSwitch unit acting as
local proxy. Port 9393 allows remote configuration of the TalkSwitch
system.
7. If available, enable Quality of Service (QoS) to give voice traffic priority
over data.
8. Save the configuration to the router.
