Push-to-talk (PTT)
PTT call to multiple devices
When there are multiple handsets registered to the phone system, PTT 
supports one-to-group calls. PTT supports a maximum of one-to-four calls 
when one to five handsets are registered, and a maximum of one-to-three 
calls when six or more handsets are registered. The first three or four 
registered handsets will be able to use this feature. Other handsets can only 
use PTT for one-to-one calls. 
To call multiple devices:
Using a cordless handset:
1. You have two ways to call multiple devices. When the handset is not in use:
Press and hold PUSH TO TAL� until the handset shows  
Connecting to group...
Press PUSH TO TAL�. Press qCID or pDIR to choose Group. Press 
SELECT or press PUSH TO TAL� and your handset shows Connecting 
to group...
When the connection is made, both the caller and the destination parties 
hear a beep. The speakerphones on all other devices automatically activate.
2. You need to press and hold PUSH TO TAL� when you want to speak. 
Speak towards the handset. Your voice is broadcast to all devices.
3. Release PUSH TO TAL� after speaking.
4. Any extension can reply (see Answer a PTT call on page 78).
NOTE: After PUSH TO TAL� is released, the PTT call remains open for a short time. If no one 
presses PUSH TO TAL� within ten seconds, the PTT call ends automatically.
