To move forward, the Yealink base must first be pointed at the Teams SIP Gateway provisioning server; only after that will the handset show the Teams sign‑in UI where the verification code from Teams Admin Center can be used.

Follow these steps in order:

1. Configure the SIP Gateway provisioning server URL
   • In the Yealink W70B web UI, go to the Auto Provision (or Provisioning) page where it asks for Server URL.
   • Enter the SIP Gateway provisioning URL for the correct region, for example:
     • EMEA: http://emea.ipp.sdg.teams.microsoft.com
     • Americas: http://noam.ipp.sdg.teams.microsoft.com
     • APAC: http://apac.ipp.sdg.teams.microsoft.com
   • Leave username/password as they are if they are pre‑filled by the device; they are not used for Teams SIP Gateway.
   • Save/apply and trigger Auto Provision so the base contacts the SIP Gateway.
   • After successful provisioning, the device should reboot and then show the Teams logo and a soft button for sign‑in on the handset.
   If the device is remote and not using DHCP options, this manual configuration in the web UI is required.
2. Ensure the device is on supported firmware
   • SIP Gateway only works with compatible devices on minimum supported firmware. If the W70B is not on a supported firmware, update it first, then repeat the provisioning step above.
3. Use the verification code from Teams Admin Center Once the device shows the Teams sign‑in UI:
   • In Teams Admin Center, go to Teams devices > SIP devices > Actions > Provision devices.
   • Under Waiting on activation, select the device and choose Generate verification code (already done in this case).
   • On the handset, dial the enrollment feature code followed by the verification code:
     • Dial: *55*<verification-code>
       • Example: if the code is 123456, dial *55*123456.
   • This validates the one‑time verification code and enrolls the device.
4. Complete user sign‑in
   • Back in the Provision devices pane, under Waiting for sign in, select Signed out for that device.
   • In the Sign in a user dialog, an authentication URL and pairing code are displayed.
   • On a PC or mobile browser, go to the authentication URL, sign in with the corporate credentials for the common area/resource account, and enter the pairing code.
   • After successful sign‑in, the handset should show the assigned phone number and username (if supported).

If Auto Provision in the Yealink UI appears to “do nothing,” verify that:

• The Server URL exactly matches the regional SIP Gateway URL (no typos).
• The device has network connectivity and can reach the internet.
• The device model/firmware is supported for SIP Gateway.
