6921 Firmware Issue

[harris.h]

Hello

We have recently upgraded our 6921 phone firmware from version  9-0-3-0 to 9-2-2-6, to our surprise the services (ext mobility and phone messenger)

have gone off the phone.

I have then reverted to another firmware version prior to 9-2-2-6, which is 9-2-1-1-sr, this has brought back the services back to the phone.

The problem appears to be inherent in the latest code 9-2-2-6.

Any ideas or similar problems please.
