The Verizon T42S IP desk phone is a Voice over IP (VoIP)
business phone with nine programmable line keys. The desk
phone and the line keys support the integrated service features
of One TalkSM from Verizon. The T42S features work the same
way on your desk phone, smartphone and tablet computers.
Initial setup
If your T42S desk phone was not connected and set up by
your IT account administrator, verify the following with
your administrator:
1. You have a One Talk number
2. Your user information has been updated in the One Talk
Admin Portal with your 911 address and email address
3. Your number has been included in any business
group features
Connecting the phone to power and Ethernet
Power
You have two options for power: AC power (wall outlet) or
Power over Ethernet (PoE). Your system administrator will
advise you which to use.
Viewing E911 location information
Enhanced 911 (E911) is a location technology that enables
emergency responders to know the geographical location of a
caller who dials 911. Your One Talk account administrator will
configure your location. Contact your administrator if your E911
address is missing or inaccurate.
Note: This device will not function unless an initial E911 address
has been added.
To view your 911 address, press the Address line key to the
right of the LCD screen.
Network
Connect the included standard Ethernet cable (or other
standard Ethernet cable) between the internet port on the
phone and the port on the wall or on your PoE-capable switch/
hub device.
Startup
After your phone is powered on, the system boots up and
performs the following steps:
Dynamic Host Configuration Protocol (DHCP)
The phone attempts to contact a DHCP server in your network
to obtain valid IPv4 network settings by default.
Automatic phone initialization
When your One Talk phone is connected to the network and
powered on, it will automatically start the initialization process.
The LCD screen displays “Initializing, please wait during this
process.” The phone finishes the initialization by loading the
saved configuration.
The desk phone is ready for use.
