Incoming PBX call during a PTT 
call 
A telephone call may be answered while in a PTT call session. To 
announce an incoming call, the handset will ring with a low-volume 
ring and display the system message. 
To answer the call, press 
Start Call
. The PTT call session will be 
pre-empted and no PTT audio will be heard. 
After the PBX call is over, press 
End Call
 as usual to go back on 
hook, at which time PTT goes out of pre-empted mode and 
becomes active again.  If an already active PTT call has not ended, 
the PTT audio starts playing again. 
If the user does not answer the telephone call by pressing 
Start Call
the PTT display will be shown after the ring has stopped. 
Making a PBX call during a PTT 
call 
To start a telephone call during a PTT call session, press the 
Start 
Call 
key. This causes the two-way radio to be pre-empted as 
described above. 
Incoming PTT call during a PBX 
call 
The PTT “receiving alert” sound will play softly in the speaker 
audio, if a PTT session is started during a PBX call.  You may 
continue your PBX call normally, or you may switch to the PTT call 
by ending the PBX call by pressing the End Call button.
