BT T48G User Manual

BT T48G IP PHONE.

USER GUIDE.

999 or 112 emergency calls.

Your BT Cloud Voice phone number is
registered to a specific address, so when
you make a 999 or 112 call from your
phone number, that’s the address the
emergency services will see. If you use
your BT Cloud Voice service at a different
address, the registered address does not
automatically change. So if your work
location changes let your BT Cloud Voice
service administrator know as they
might also need to change your
registered address.

You might not be able to make 999 or
112 calls when there’s a power or
network failure or if using the service
through an app on a mobile device.

There are two options for power and network connections. Your system administrator
will let you know which one to use.

AC power (optional)

To connect the AC power you need to:

1. Connect the DC plug on the power adapter to the DC5V port on the phone, then
connect the other end of the power adapter into an electrical power outlet.

2. Connect a standard Ethernet cable (included) between the Internet port on the
phone and the one on the wall or switch/hub device port.

Power over Ethernet (PoE)

Using a standard Ethernet cable (included), the BT T48G IP Phone can be powered
from both a PoE-compliant switch or hub. Simply connect the Ethernet cable
between the Internet port on the phone and an available port on the in-line power
switch/hub.

Connecting the network
and power.

PHONE INSTALLATION.

Note:

If an in-line power switch/hub has
been provided, you won’t need to
connect the phone to the power
adapter. Just make sure the switch/
hub is PoE-compliant. The phone
can also share the network with
another network device such as a
PC. It’s an optional connection.
Important! Don’t unplug or remove
power to the phone while it is
updating firmware and
configurations.

When all the connections are made, your BT T48G IP Phone is pre-loaded with
everything it needs to provision the BT Cloud Voice Service automatically.

1. When the phone is connected to the network port giving it network access, it’ll
carry out a series of firmware updates (you’ll need to allow it time to do this).

• Your phone has provisioned correctly if this symbol

is showing against

the phones line key.

• Your phone has not provisioned correctly if this symbol

is showing

against the phones line key.

2. Once complete, the phone will now show the line number against a line key.
