Multiple handset use

Push-to-talk (PTT)
You can directly broadcast messages to the speakerphone of a 
group of handsets. Any handset you call can respond by pressing 
the PUSH TO TAL� key to begin two-way communication. 
Only one handset can talk at a time. To do so, press and hold 
PUSH TO TAL�. 
You must release PUSH TO TAL�, so another person can respond.
Only one PTT session can be active at a time.
While PTT is in use between two handsets, other handsets cannot use the 
intercom feature but can access the answering system.
When you attempt to place a PTT call to another handset which is 
accessing the answering system or on an intercom call or outside call, 
your handset screen shows Not available at this time.
NOTE: The PTT function is not available when QUIET mode is on.
