Yealink T31P Desk Phone
The Yealink T31P is the simplest desk phone Netexem installs: a backlit 2.3-inch screen, two line keys, PoE and HD voice for $50, or free with a service agreement, from Netexem in Tustin for businesses across Orange County and Southern California. Call 714.444.0550 for a quote.
It rings, answers, holds, transfers and joins a conference, with the same clear sound as the pricier models and nothing to learn. This page lists the specs, where it belongs, the few settings people look up, and how it compares with the T33G, the T34W and a cordless handset.

Who the T31P is for
A warehouse wall, a loading dock, a lobby courtesy phone, a kitchen, a break room, a spare desk, an exam room or a workshop bench: places that need a phone on the wall or the counter, not a screen full of names. The backlit display shows who is calling, two line keys cover the main line and one more, and the headset port suits a parts counter that talks all day. A desk that transfers calls or watches colleagues' lines wants the T33G, T34W or T73W; a person who walks the floor wants a cordless handset instead.
Yealink T31P quick guide
The steps people look up most, in plain words. Menu names match the T31P's own screen.
How to factory reset a Yealink T31P
- With the phone idle, press and hold the OK key until it asks whether to reset to factory settings, then confirm.
- From the menu instead: Menu > Settings > Advanced Settings (default password admin) > Reset Config > Reset to Factory Settings > Reset > OK.
- Leave it powered on until it has restarted completely.
Note: A Netexem T31P sets itself up again after a reset: back on the network, it downloads its settings and returns with your extension and voicemail. Call 714.444.0550 first; most problems are fixed remotely.
How to find the IP address of a Yealink T31P
- With the phone idle, press the OK key, or go to Menu > Status.
- The IPv4 address is on the first line of the status screen, with the firmware version below it.
You only need this to open the phone's web page from a computer on the same network. On Netexem service we handle that for you.
How to change the ring volume and ringtone on a Yealink T31P
- While the phone is idle, press the volume key left or right to set how loud it rings; the screen shows the level.
- To pick a different ring, go to Menu > Settings > Basic Settings > Sound > Ring Tones and choose one with the up and down keys.
- Press Save. Silence it for a meeting with the DND soft key; press it again when you are back.
How to use a headset with a Yealink T31P
- Plug a wired headset into the RJ9 headset port on the back of the phone (the one with the headset icon), not the handset port.
- Tap the headset key once; while its light is on, every call goes to the headset instead of the handset. Tap it again to switch back.
- With a Yealink wireless headset, the EHS35 adapter lets the button on the headset answer and hang up.
No USB and no Bluetooth on this model: for those, see the T34W or T73W.
Voicemail, call forwarding, hold, conference calls and intercom work the same on every Netexem phone; see the Netexem phone system user guide.
The full Yealink manual covers every feature; the T31P datasheet lists the specifications. Netexem customers can simply call 714.444.0550 and we walk you through it.
Yealink T31P compared
T31P vs T31W
T31W: $60
The same phone with Wi-Fi built in, $10 more: the pick for a desk with no network cable.
T31P vs T33G
T33G: $70
$20 more buys a colour screen, 4 buttons and Gigabit ports; the better pick for a desk that transfers calls.
T31P vs T34W
T34W: $80
Colour screen, 4 buttons, Wi-Fi and USB for $30 more; the phone for a spot with no network cable.
T31P vs W70P
W70P: $129
A cordless base and handset instead of a desk phone: for a warehouse or shop where the person, not the desk, needs the phone.

Yealink T31P questions
How much is the Yealink T31P from Netexem?
$50 one-time per phone on the month-to-month plan, or included free with a service agreement. Phone service is $19.99 or $29.99 per user per month, fixed, with free installation, training and number porting and no long-term contract.
What is the difference between the Yealink T31P and T31G?
Network speed. The T31G has Gigabit ports; the T31P has 10/100 ports, which is plenty for a phone and fine for a computer that does ordinary office work behind it. Everything else is the same. Netexem stocks the T31P; a Gigabit desk usually steps up to the T33G.
Does the Yealink T31P support PoE?
Yes. With a PoE switch the network cable powers the phone and no outlet is needed. Without PoE it uses the 5 V power adapter, which Netexem supplies for $5.
What is the default password on a Yealink T31P?
The factory default admin password is admin, for the phone's Advanced Settings menu and its web page. On Netexem service the default voicemail password is 1234#; change it after your first login.
Who installs the Yealink T31P?
A Netexem technician from our Tustin office installs it on site anywhere in Orange County and Southern California and trains your staff on install day. If you install yourself, we ship the phones to your office anywhere in the US; the phone sets itself up when plugged in and we guide you by phone or screen share.
