Explanation
One or more of the following factors might apply:
• You must log into the Extension Mobility service.
• You must enter a client matter code (CMC) or forced authorization
code (FAC) after dialing a number.
• Your phone has time-of-day restrictions that prevent you from using
some features during certain hours of the day.
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 requires multiple selected calls. Be sure that you have selected at least
one call in addition to the active call, which is selected automatically.
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.
You will be disconnected from a call that you have joined using Barge if the
call is put on hold, transferred, or turned into a conference call.
The other party might have call forwarding enabled.
