Multiple handset use

Push-to-talk (PTT)

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 two 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 begin a PTT call to a group of handsets:

Press and hold PUSH TO TALK when the handset is not in use.

Press PUSH TO TALK when the handset is not in use. Press TONE

the connection is made, both your and the destination handsets display
