• You must log into the Extension Mobility service.
• You must enter a client matter code or forced authorization code after
dialing a number.
• Your phone has time-of-day restrictions that prevent you from using
some features during certain hours of the day.

The softkey that you
want to use does not
appear One or more of the following factors might apply:
• You must press more to reveal additional softkeys.
• You must change the line state (for example, go off-hook or have a
connected call).
• Your phone is not configured to support the feature associated with
that softkey.
Join fails Join requires multiple selected calls. Be sure that you have selected at least
one call in addition to the active call, which is selected automatically. Join
also requires the selected calls to be on the same line. If necessary, transfer
calls to one line before joining them.
Barge fails and results
in a fast busy tone You cannot barge an encrypted call if the phone you are using is not
configured for encryption. When your barge attempt fails for this reason,
your phone plays a fast busy tone.
