2. If you are setting up an external IP extension, select the Time Zone of the IP phone.
3. Enter the Phone MAC Address. This is a 12-digit alphanumeric string located in the barcode.
The MAC address allows the TalkSwitch unit to connect to the IP phone and automatically
configure it.
4. Choose File > Save. The system will create a configuration file that the phone will download
when the phone is restarted.
Configuring the system for external IP extensions
If you are setting up an external IP extension:
1. Ensure your TalkSwitch system is connected to a network.
2. Ensure that you have set up a public IP address for the TalkSwitch system.
3. Ensure the router is configured at the TalkSwitch location. There should be no need to make
any adjustments to the firewall at the remote location.
4. All VoIP lines are shared by default. You can also reserve VoIP lines for external IP
extensions.
5. External IP extensions will use the preferred codec selected for the TalkSwitch profile. The
default preferred codec is G.729. You can select a different preferred codec for the
TalkSwitch profile.
Configuring the router
If you are setting up an external IP extension, you must ensure the router is configured.
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.
