I haven't been in too many lounges and I don't if you are referring to Star alliance lounges only. I have never been in a Star Alliance lounge.
The US domestic lounges that I know of that have complimentary drinks are DL, NW, CO, HP.
Every DL lounge I have been in has computers with internet access.
I couldn't tell you anything about free local calls.
I hope this helps. Sorry, I have no knowledge of UA lounges.
