VoIP and regular calls using all the handsets.
Note: If you have a wireless network that operates over the typical
2.4GHz frequency and you want to use cordless phones, it is best if
you use 900MHz or 5GHz phones; that way, you will minimize any
chance of interference.
Install the X5v Where Your Phone
Line Enters Your Home (USA Only)
In many homes, there is a telephone jack where the phone line
enters the house. This box is called the "demarcation point." It
marks the point where the Phone Company's wiring ends and your
wiring begins. This is an excellent place to install your X5v and
connect it so that it provides VoIP capability to all the phones in
your home.
There is a catch. To use the ADSL line, you need to connect your
X5v gateway to the demarcation point's jack and to either a wired
or wireless network. If you have a wired network, you simply run a
network cable to the gateway as you would in a typical installation
scenario. If you don't have a wired network, plugging the gateway
into an 802.11 wireless access point is a fast, inexpensive, and
convenient way to deliver your ADSL connection to one or more
computers without running wires.
To connect your phones, disconnect the modular plug at the
demarcation point and plug it into the X5v's jack marked
PHONE. (If the demarcation point doesn't have a modular plug,
you will need to unwrap the wire that is providing the connection.
You may have to call a technician if you do not have a modular
plug.) Then connect one end of the phone cord that came with the
X5v into its ADSL jack and the other end into the jack on the
demarcation point. With the computer's power off, check that your
phones work normally.
