Voice Channel Signaling Security 
 
Implementing features, see also Manager E Voice Channel Signaling Security

Definition  
This feature is a security device, which prevents tone injections in the voice channel. This avoids data corruption in the voice channel. A station configured as a fax machine automatically receives signaling security. In this state, no tones whatsoever are injected in the voice channel. Users cannot override this connection.
optiPoint 500 and OpenStage TDM telephones can also be protected by programming the feature "Call Waiting Rejection" in the database. Callers will not be able to camp on and will continue to receive busy tone.
This feature can only be set via database. For optiPoint 500 and OpenStage TDM telephones with display, refer to the "Requirements/Conditions" table below for an alternative.

This feature does not function with ISDN terminals.  
Recalls  
Recalls are postponed until the stations are free.  
Call waiting  
The call waiting tone can also be suppressed from telephones with a display (optiPoint 500, OpenStage), using a procedure (*87=Call waiting tone off; #87=Call waiting tone on. This has no effect on display signaling.  
Call hold  
A station on hold always has signaling security.  
Conference  
If a station in a conference has activated call waiting rejection, an unprotected station can still be camped-on.
