its not just 1 call, all calls are free on christmas, but my battalion has put a 15 minute time limit on calls, and its going to be so packed , people seem to come out of nowhere on holidays for the phones, usually its empty at the phone center . we have video conferences every once in a while but those are short too, and its for married soldiers generally cause they host it back in garrison and not many family members live even in the same state as our duty station, also we have webcams but the internet is so dreadfully slow here its a pain trying to get it to connect
