I will choose Simplisafe as my security provider. I will also choose the most expensive plan to assure that I have all of the features available to me. I will have to figure out what they would need to do if they needed to call me, and give them the appropriate number in turn. This could likely be the forwarding number which will ring the cellular, and home phone line at the same time. The office will host my home phone when I am not home, and that door will be locked to protect the office’s resources.
