In the Binar episode in TNG Picard just hits his comm badge and is talking to a Starfleet Base or something. Were the Comms badge always able to operate like this , allowing the crew to talk to anyone in the Galaxy. Or was this just a one off for this episode?
Also on TOS they would get on the internal communication devices (on the wall) and say something like bridge to Captain Kirk and somehow it would be directed to wherever Captain Kirk was. If he was in the Gym or walking through a corridor. If the internal sensors on the ship were good enough to always know where Captain Kirk was surely they would know that Finney was still on the ship or where various aliens were on the ship at all times (Klingons, Khan, etc).
Don't start me on the doors (opening/closing) in TOS...
