What does the little walkie talkie symbol in the upper left portion of screen mean?

When exploring new areas or starting a mission I sometimes get a walkie talkie symbol in the upper left portion of the screen. I know that sometimes you get like a binocular symbol or an arrow symbol signifying that something was added to the map.

What does the walkie talkie mean?
