Yealink T21P_E2 firmware

[gaselec]

About 2 weeks ago both Yealinks shown below started to display 'Not supported 52.84.0.95' I updated one phone using the 3CX system and it now displays 52.84.0.140 . See below.
No functions seem impaired in limited testing. This is a non critical system. However we have a large number of refurbed Yealinks going into a project which have all been brought up to 52.84.0.95. I thought this was the current recommended FW version and can't see mention of .140 anywhere.
Running Version 16.0.1078 on local VM
Comments please.

Hello,

52.84.0.140 is the latest version supported by 3CX, you can see our latest by following this link

As for the existing phones, you can provision them when you deploy and upgrade them from their PBX.
It is however a good idea to set them up on a test PBX and upgrade them from there so they are ready to deploy when the time comes.

Many thanks for prompt and informative reply. My search didn't show this up for some reason, my fault.

Sadly they were all set up on a test PBX a month ago just as you suggested - and then shipped! But it's not a large system and easy to do.

Yep, and if the deployment will be done soon then I think you won't have any issues provisioning and then upgrading them on site. Might just add a bit of time on the day of deployment
