Two-player voice chat inside trigger volumes?

Hi all.

I’m basically trying to make a two-player game in which, at certain points in the map, voice chat is enabled by a trigger volume - so for instance, the two players are completely separated. They cannot talk or communicate, and eventually they meet at a window - while they’re by the window, they are able to talk through the microphone to each other.

From what I’ve seen there’s not really an (obvious) answer for doing this via Blueprints, unless I’ve missed something – if not, I have no knowledge of C++. Would this be simple enough to do in C++ in an otherwise blueprint-based game for someone who isn’t familiar with C++?

Any help would be fantastic, thanks!
