Yep - that's right, its 24 hours a day, 7 days a week, all year. All of the call answering services are setup into our call answering platform and are answered by operators. We staff the phones all day every day. Obviously, we don't get many calls after 10pm at night, so it's skeleton staff until 7am the next day - but we always do our best to answer every call that comes through.
We get this question so many times so hopefully this has straightened it out.
