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 four registered handsets will be able to use
this feature. Other handsets can only use PTT for one-to-one calls.
To call a group of handsets:
1. Press and hold PUSH TO TALK until the 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 device can reply (see Answer a PTT call).
