IP extension details area
If you connected a TalkSwitch TS-9112i, TS-9133i or TS-480i IP phone to the LAN and used it to
select an extension number, the IP Extension Details area for that extension will be complete.
If necessary, perform the following steps:
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. 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 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.
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.
