W52P Handset Firmware Upgrade

[trilan_steveg]

Hi there, I am installing my first ever W52P with 2 handsets.

All is working well, the only problem I have is upgrading the 2nd handsets firmware (it doesn't)

Under status the 2nd handset firmware column is blank.

I know I could do it via a pc and cable but Once this unit is out in the field I don't really want to have a 400 mile round trip every time I need to upgrade the firmware.

Is this by design or do I have an issue? Base unit is on newest FW and so is handset 1 now.

No idea why this may help but it is installed on a 3CX.

Also if anyone knows if there is a way to do the Autoprovision on the handset 2+ I would be grateful.

Thanks in advance

Steve

Possible cause is that the firmware of the handset is not equal to the base firmware.

You can flash the firmware of the handset “Over the air” but if this is not possible for what kind of reason, you have to use the cable and pc.

Personally it think you have an issue and it could be that the handset contain “customized” firmware, not Yealink’s native 26.xx.0.1 but something like 26.40.115.1 or 26.40.188.1
If your handset have this firmware, then you have to ask your reseller for the latest firmware.
