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-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 able to use this feature. Other handsets can only use PTT for 
one-to-one calls.
