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 WT 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

described above.
Incoming PTT call

The PTT “receiving alert” sound will play softly in the speaker

End Call button.
