Should I be compensated for my on-call time?

I work in IT support for a health care company. Every few weeks, I have to be on-call. During this time, I am required to have my laptop and a wifi hotspot (provided by the company) nearby at all times. I am required to abstain from alcohol during this time as well. This on-call time begins 30 minutes after I leave the office and continues until the first member of my team arrives the next workday, usually 30 minutes before I arrive. This also includes the entirety of weekends, from Friday evening through Monday morning, day and night. We are held to a 15-minute response time, meaning, if I miss a call, I am required to respond to it within 15 minutes to the best of my ability. If it is found that I did not meet his response time, I can be written up or otherwise reprimanded. My question is: Should I be paid for the entire time I am on-call? I am currently only paid for the time I actually spend on the phone/PC, but I don't believe this response time allows me to live normally.
