The idea is taken from cs. ingame teamspeak.
I think noone has mentioned it earlier but i might be wrong. I do not know if this is possible from a technical point of view but definitely , it would be a cool thing. That kind of communication is better. Sometimes you don't pay attention to what people are texting in game and you may overlook the valuable information , like ' where's the efc ' whereas if someone said it through the ingame ts, you would have heard that. If someone does not like to talk , he doesn't even have to. It's push to talk. But it's better to hear the information than look for it in a heap of dialogues. I find this better than the radio thing. Definitely it's faster and it's a facilitation , especially for the newcommers. Also you are learning faster if you are receiving some tips from better players. People can talk with eachother , not just about the current action but generally about everything that is related to Soldat. All this can be made by ingame ts. You start to talk just by pressing one button , for example 'f'. When you don't want to hear all these conversations there should be a disable button too.
