Push-to-talk (PTT)
�TT 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.
