When I was trying to approach to the source of the sound, I noticed that my colleague was doing the same thing too. We were searching for the source of the voice because no one was in the building except us! It sounded like a woman shouting and saying 'Hello! Hello!'. So we confirmed out it was from a mobile phone. So? Nothing unusual right? People make calls and uses their loudspeaker at times but still something was unusual there... She kept on talking but I guess that the woman didn't know that there was no one there! The weird thing is that the conversation went on like 5-8 minutes (she should by now realize that there is on one there)! She was still talking alone and her tone was more like sobering or something. In her speech there was some vulgar words like 'F**k you!' and something else. She was speaking in Tagalog language and I can't understand a thing (except for the 'Hello' and those vulgar words). I guess it could be some girlfriend of someone who was love sick? Beats me!
Anyway, I guess the phone was set to auto-answer and it can be at times invites some unsatisfied people who could get angry over it as they thought you answered their call but it turns out no one was there! So watch out as technology which should help us can backfire if we're careless! :P
