Introduction
The TL7912 is a cordless headset and base that allows you to
have handsfree phone conversations. The package also comes
with the TL7100 handset lifter, making it convenient to answer
and end calls right from the headset. It can be used in different
ways depending on your needs. Choose from the following three
options. Connect your TL7912:
To a traditional corded telephone (pages 15-16). Connect the
headset base to a corded telephone and install the lifter on
your corded telephone. You can use the headset to remotely
control the lifter for answering or hanging up a call.
To both a corded phone and computer (pages 17-20).
Connect the headset base to a corded telephone and install
the lifter on your corded telephone. Use the USB cable to
connect the headset base and your PC. You can make and
answer VoIP calls through Skype or Microsoft Lync, or landline
calls using the AT&T Softphone Call Manager. You can also
use the voice command feature to make or answer calls after
you have installed the AT&T Softphone Call Manager.
Install the AT&T Softphone Call Manager using the
CD-ROM provided in the package.
-OR-
Visit www.telephones.att.com/downloads to download
the software. Unzip and install the file after download.
For installation and operation instructions of the software, refer
to the Installation and Operation Guide which can also be
found in the CD-ROM provided or the web site stated above.
To a telephone line only (page 21). If you do not want to
install the lifter on the corded handset, you can simply connect
the headset to a telephone wall jack through the line splitter
provided. Use the telephones on the same telephone line to
make or answer calls. The headset is a supplementary device
that can join the calls.
