Multiple handset use

Push-to-talk (PTT)
PTT call to group
When there are multiple handsets registered to the phone system, PTT 
supports one-to-group calls. PTT supports a maximum of one-to-five calls 
when one to five handsets are registered, and a maximum of one-to-four 
calls when six or more handsets are registered. The first four registered 
handsets will be eligible to use this feature. Other handsets can only use PTT 
for one-to-one calls. 
To call the group using a cordless handset:
1. You have three 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 TONE  followed by # (pound key). 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.
