Sadly, yes they are all same region.

hardware ID on working phone : 61.0.0.14
on broken one: 61.0.0.11

Firmware 61.81.179.1
vs
61.83.188.3

When i click on line status, on the working phone it just shows the number.

On the phones that don't work, it shows the number, then a small red icon underneath showing a phone icon and a stop sign.

Hi,

What could be the cause is that the new W56H and base run on "Deutsche Telekom" special edition (xx.xx.179.xx) firmware and therefore do not communicate well with both used handsets (xx.xx.188.xx).
You could consider upgrading the W56P / W60P base to the latest xx.xx.0.xx firmware, if possible, so that everything communicates properly again. This is at you own risk or contact DT first.
The handsets can be upgraded with the latest firmware via OTA.

Please tell me the model (W52P/W56P/W60B) and firmware of the base.
Here you find the Yealink firmware:
W56P - http://support.yealink.com/documentFront...mentId=110
W60P - http://support.yealink.com/documentFront...mentId=206

It is a W60B
firmware: 77.83.179.1

Hi,

Please contact DT or your reseller and ask if the devices will work with each other if the firmware (77.83.179.1 <-> 61.83.188.3) is different.

FWIW: My W60B running on f/w 77.83.0.85 work with W53H running on f/w 88.83.188.7 so I guess the issue is not caused by the .188 firmware.
