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 ve handsets are registered, and a maximum of one-to-
three calls when six or more handsets are registered. The rst 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:
f Press and hold PUSH TO TALK until the handset shows
Connecting to group....
f 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).
Note: After PUSH TO TALK is released, the PTT call remains open for a short time. If no one presses
PUSH TO TALK within 10 seconds, the PTT call ends automatically.
