  Users could press the EndCall softkey or simply hang up the call to terminate the conference call. 
 
Note:   
  The party that starts the conference call has to remain in the conference for its entire duration, you can 
put the party on mute but it must remain in the conversation. Also, this is not applicable when the 
feature "Transfer on Conference Hangup" is turned on. 
  The option "Disable Conference" has to be set to "No" to establish conference. 
  When using Easy Conference Mode, use SEND key to dial out the second call instead of using #, 
even when # could be used as SEND in normal phone calls. 
 
VOICE MESSAGES (MESSAGE WAITING INDICATOR) 
 
A blinking red MWI (Message Waiting Indicator) on the top right corner of the phone indicates a message 
is waiting. Dial into the voicemail box to retrieve the message by entering the voice mail number of the 
server or pressing the Voicemail button (Voice Mail User ID has to be properly configured as the voice mail 
number under Web GUI->Account x->General Settings). An IVR will prompt the user through the process 
of message retrieval. 
 
SHARED CALL APPEARANCE (SCA) 
 
The  GXP2140/GXP2160  phone  supports  shared  call  appearance  by  Broadsoft  standard.  This  feature 
allows  members  of  the  SCA  group  to  shared  SIP  lines  and  provides  status  monitoring  (idle,  active, 
progressing, hold) of the shared line. When there is an incoming call designated for the SCA group, all of 
the members of the group will be notified of an incoming call and will be able to answer the call from the 
phone with the SCA extension registered.   
 
All the users that belong to the same SCA group will be notified by visual indicator when a user seizes the 
line and places an outgoing call, and all the users of this group will not be able to seize the line until the line 
goes back to an idle state or when the call is placed on hold (with the exception of when multiple call 
appearances are enabled on the server side). 
 
In the  middle of  the  conversation, there are two types of  hold: Public Hold  and  Private Hold. When a 
member of the group places the call on public hold, the other users of the SCA group will be notified of this 
by the red-flashing button and they will be able to resume the call from their phone by pressing the line 
button. However, if this call is placed on private-hold, no other member of the SCA group will be able to 
resume that call.   
 
To enable shared call appearance, the user would need to register the shared line account on the phone.
