How to get the best from your Yealink AX83H Wi-Fi Cordless to Your Phone System
And get the most out of its smart features
If you’ve just unboxed your shiny Yealink AX83H Wi-Fi cordless handset, you’re probably itching to get it connected and working with your phone system. Good news — it’s easier than assembling flat-pack furniture.
Below is a simple step-by-step guide plus a walkthrough video so you can see exactly what’s happening as you do it.
Watch the full setup & feature demo above — all the essentials are covered!
Step 1 — Power & Wi-Fi Setup
- Power up your Yealink AX83H.
- Navigate to Settings > Wi-Fi.
- Choose your network and enter the password.
- Wait for the “Connected” confirmation.
Why it matters: Connecting to Wi-Fi gives you mobility — no desk cables holding you down. As long as you have a good WiFi network, your phone will work wherever there is WiFI coverage.
Step 2 — Register with Your Phone System
You’ve got two options here:
A) Auto-Provision (if your phone system supports it)
Most modern VoIP phone systems (like the ones we set up at KAT) can automatically provision Yealink devices. Once connected to Wifi let the phone do its thing and it will reboot itself pre configured onto your phone system.
B) Manual SIP Registration
Grab your SIP credentials from your phone system (extension, password, server) and store them into:
Menu > Accounts > SIP Account
Pro Tip: Make sure the SIP server address and port are exactly right — tiny typos can cost you hours of hair-pulling.
️ Step 3 — Test a Call
Once registered:
Make a test call
Try voicemail (if enabled)
Transfer a call
This confirms everything is talking to each other properly.
Great Features You Should Definitely Try
Here’s where the AX83H stops being “just a phone” and starts being a productivity tool:
✨ Seamless Wi-Fi roaming
Walk around your office without losing the call. Real talk: this is game-changing for reception teams and floor staff.
HD audio & noise reduction
Calls sound crisp even in busier environments.
️ Visual voicemail & call logs
Quickly see who called and why — perfect for busy admins.
