Configuring the TS-850i/TS-860i for use outside
the office
An external IP extension is located outside the office (e.g.
an office phone within the home), and connects to your
TalkSwitch system over the Internet. The TalkSwitch
system must be equipped with a VoIP module.
Checking the firewall
Run the firewall test to ensure the appropriate ports are
forwarded from the router at the TalkSwitch location to the
TalkSwitch unit acting as proxy. There should be no need to
make any adjustments to the firewall at the remote
location. For more information, see
Router port forwarding
in Help within the TalkSwitch management software.
1. Launch the TalkSwitch management software.
2. Select the
IP Configuration
page.
Warning:
Calls to an emergency service number using
an external IP extension will not send the correct
address to the emergency operator. We strongly
recommend that you apply a warning label to any
external IP extension stating:
If an emergency call is made from this phone, you
must provide your address to the emergency
operator.
