To send a PTT message
Navigate to the Channel you wish to message with Push-to-talk. Press and hold the spacebar to talk live.
To Page a User
You are only able to Page an individual user, not a Group Channel or Admin Defined Channel.
Navigate to the User you wish to Page and click the Page icon located to the right side of their name.
After clicking on Page, a confirmation prompt will appear, click Yes.
The receiver of the Page can either accept or ignore the Page. A record of if the Page was missed, accepted, or rejected will be chronologically placed in the channel thread.
