T28P foward call doesn´t work with 2.73.0.50

[Tato]

Hi, we have several Yealink T series phones in our company.
We recently update some firmware and foward call doesn´t work.
We update from 2.61.0.80 to 2.73.0.50
We have to downgrade to 2.72.0.30 to make foward call work.

Firmware Version: 2.72.0.30
Hardware Version: 1.0.0.39

I need to do seomething to get foward call work on new firmware version?

Regards,
