I have a client with the screen sometimes not showing a softkey transfer button when calls are answered.

Cisco Phone Model #7962 with a 7915 module.

Trouble occurs when one user forwards calls to reception. When forwarded calls are answered, the screen does not show a transfer button. Issue is intermittent, and comes on occasionally.

Screen should show these soft keys: hold, end call, transfer, more
4 buttons with three screens:

screen 1: hold, end call, transfer, more
screen 2: park, xxxx, conference list, more
screen 3: select, join

Has anyone had the same issue and resolved it?
I am guessing it shows screen 3 and she doesn't see a "more" button, or the "back" button to go to screen 1, but the question remains, why would it show a different screen? ...and only when receiving calls that are forwarded?
