First time set up of Yealink SIP Phone
Published 8 April 2025 revised.
Only Dialpad Admins can provision Yealink deskphones against a User or Room Phone license.
Before doing the SIP Configuration, it's important to request sip_phones to be added to your account. Request from support@untangled.com.au
This procedure is for Yealink T3, T4, or T5-series desk phones whose front display shows anything except Dialpad Activate.
This procedure also applies to new Yealink or Poly cordless phones that need to be configured to a Dialpad user or room license.
Preparation Checklist:
-
Power Source: Ensure the phone is connected to a power source (via adapter or PoE - Power over Ethernet connected from the deskphone internet port to your router. A PoE powers up your Yealink deskphone too).
-
Network Connection: Connect the phone to the same network as your desktop as this is needed to be able to access the deskphone GUI or log in page.
-
IP Address: Find the phone’s IP address via Menu > Status or pressing OK when idle.
-
Admin Credentials: Have the admin login (default: admin/admin) for the web interface.
-
SIP Server Info: Get SIP account details from Untangled. This is your username, password, and server information.
-
Web Browser Access: Use a browser to access the deskphone’s GUI for configuration.
- AnyDesk app: Download via anydesk.com/download so our support team can do all the work by remote accessing your computer
Factory Reset: To configure a Yealink T series deskphone previously set up with a different provider, a factory reset must be performed first.
