Multiple handset use
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:
You have two ways to call multiple devices. When the handset is not in use:
Press and hold PUSH TO TALK until the handset shows Connecting
to group....
Press PUSH TO TALK. Press CID or DIR to choose Group. Press
SELECT or press PUSH TO TALK 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 TALK when you want to speak. Speak
towards the handset. Your voice is broadcast to all devices.
3. Release PUSH TO TALK after speaking.
4. Any extension can reply (see Answer a PTT call on page 84).
