Avaya 3600 Series Manual Do Utilizador

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 

. The PTT call session will be 

pre-empted and no PTT audio will be heard. 

After the PBX call is over, press 

 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 

, the PTT display will be shown after the ring has stopped. 

To start a telephone call during a PTT call session, press the 

key. This causes the two-way radio to be pre-empted as 

described above. 

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 

 button.
