Since the magic jack is connected to the home server, it will be on 24 hours a day 7 days a week. Also, the jack is connected with a wireless phone. The 2nd wireless phone is placed in the living room in which the volume is so low. Good thing I figured it out how to adjust it and now it can be heard loudly anywhere in the house. Hope nobody will dial this magic jack during middle of the night or early morning. Chow!
