IP extension details area
1. Set the Location. Choices are:
• Internal — The phone is an internal IP extension located within the office, and is
connected to the same LAN as the TalkSwitch unit.
• External — The phone is an external IP extension located outside the office, and is
connected to the TalkSwitch unit over the internet. See External IP extensions on page 2
2. If you set Location to External, select the Time Zone that matches the location of the
IP phone.
3. Select the MAC Address of the phone:
• You can select the Phone MAC Address from a list of automatically-detected phones
connected to your LAN. To use this method:
i) Click the Select… button. A MAC Selection window appears and lists TalkSwitch IP
phones of the selected type.
ii) Select the MAC address of the IP phone associated to the extension, and then
click Select.
• You can enter the Phone MAC Address manually. This is the required method if you are
setting up an external IP extension. The MAC Address is a 12-digit alphanumeric string
located in the barcode on the bottom of the phone and the box the phone came in.
Note that multiple IP extensions can share the same base.
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.
