Talkswitch CT.TS005.003904 User Manual page 104

• External — The phone is an external IP extension located outside the office, and is
connected to the TalkSwitch unit over the internet. A VoIP-enabled TalkSwitch unit
is required.
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 you are setting up an external IP extension, select the Time Zone of the IP phone.
3. Ensure the Phone MAC Address is complete:
• The Phone MAC Address will be complete, if you connected the phone to the LAN and
used it to select the extension number.
• You can select the Phone MAC Address using the MAC Assignment window, if you
connected the phone to the LAN, but did not use the phone to select the extension
number. To use the MAC Assignment window:
i) Click MAC Assignment. The MAC Assignment window appears and lists TalkSwitch
IP phones of the selected type that are connected to the LAN.
ii) Select the MAC address of the IP phone for the current extension, and then
click Select.
• You can enter the Phone MAC Address manually, if you did not use the phone to select
the extension number. This is required if you are setting up an external IP extension.
The MAC Address is a 12-digit alphanumeric string located in the barcode on the box the
phone came in. It allows the TalkSwitch unit to connect to the IP phone and
automatically configure it.
