Virtual Voice Mail 
Functionality   
With this feature, phone downloads the voicemail into a .wav file and stores it on the phone for the user. 
Users don’t have to dial feature codes and go to the BroadSoft server to listen to their voice mails. Also, 
users can pause/resume their voicemail message at any time they want.   
Note
: Currently this feature works with Broadsoft server. 
Shared Call Appearance (SCA) 
The  GXP2130/GXP2140/GXP2160/GXP2170/GXP2135  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 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 (except for 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. 
In addition, they would need to navigate to "Settings""Programmable Keys" on the web UI and set the 
line key mode as "Shared Line". If the user requires more shared call appearances, the user can configure 
multiple line buttons to be "shared line" buttons associated with the account. 
Call Forwarding Rules Enhancement 
Users can access their call forwarding from the phone without erasing the configured numbers. On the 
phone,  you can  access  through  “MenuphoneCall FeaturesAccount X”  When disabled  the  LCD 
screen will look like the following figure.
