Warning: Using an external IP extension to call an emergency service number 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.
2. If the phone can be used as an external IP extension, select the Time Zone of the IP phone.

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. See Connecting to a network on
page 218.
2. Ensure that you have set up a public IP address for the TalkSwitch system. See Public IP
address on page 35.
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. See Router port forwarding on page
36.
4. All VoIP lines are shared by default. You can also reserve VoIP lines for external IP
extensions. See Reserving VoIP lines on page 53.
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. See Setting codec options on page 56.
