This includes through their management console and manually through the web GUI of the T27G. Was using 3cx provided Firmware, T27G-69.84.0.95, but also tried Yealinks T27G-69.84.0.90.

Currently on:
Version
Firmware Version 69.83.0.55
Hardware Version 69.0.0.0.0.0.0

Hi,

Please follow next steps and try again:

- Reset the phone(s) to Factory default and do not re-provisioning.
- Download the T27G-69.84.0.90.rom file directly from the Yealink site (http://support.yealink.com/documentFront...entId=138)
- Manually update the phone(s) with the downloaded file
- Reset to Factory default and check on the new firmware version
- Re-provisioning the phone

Hope this will help.
