Operational IP Phone Features
BLF and XML softkeys/programmable keys monitor the states of an extension. 
The extension states can be one of three states: "busy", "ringing" and "idle". If the 
monitored extension is in the "ringing" state with an incoming call, and "Directed 
call pickup" is enabled, pressing the BLF or XML key can pick up the incoming 
call on the monitored extension.
Playing a Ring Splash
You can also enable or disable the playing of a short "call waiting tone" when 
there is an incoming call on the BLF or XML monitored extension. If the host 
tone is idle, the tone plays a "ring splash".
You can enable/disable “Directed Call Pickup” and “Play a Ring Splash” using the 
configuration files or the Aastra Web UI.
Note: 
The Asterisk and Epygi Quadro 4x/16x IP PBX servers support 
this feature.  For details about Asterisk support, contact Aastra Technical 
Support.
Note: 
Both the “Directed Call Pickup” feature and the “Playing a Ring 
Splash” feature are disabled by default.
