The Device Level of the logged of phone that has a physical Add on unit connected to it will need to have the Add On programmed.

The Device Profile of the logged off phone does not need it (red lights will show) but the Device Profile of the User that you want to log on needs to be programmed for the Add on

Till I am not able to understand the solution, extension mobility is working, BLF is working when IPPhone are logout.

When IPPhone are login for extension mobility, the BLF function is not working..Please point the config I am missing.

you have to understand the difference between the Device Level (the physical phone on the desk) and the Device Profile (software that can log on to any phone)

The Profile should contain the Information that a Add On Unit is supported and should have the correct key layout programmed.

The Physical Phone needs to have the Add On Unit installed and the Device Profile of the Phone needs to be programmed that a Add On unit is installed.

Only then wehn you log on to a phone with an add on unit the device profile will be able to use the device level of the phone.
