I have 2 separate setups to concern myself with. The first is my personal telephone numbers. This is a cellular, home, forwarder, fax, and voicemail number. All of these numbers will have the same last 7 digits of the phone number leaving the first 3 digits are different. While the purchase of the three numbers will be considered as a significant purchase, the phone service is not. I will be the sole user of the office that would be on the fourth floor. In that office will be my 412 number, and my 724 number.
In addition to the numbers I will have, I will also have 2 telephone numbers intended exclusively for the residence. If I was to order a pizza, I will use the residence number. Also, the intercom system will be tied to the residence phone line. In addition to the residence phone number, there will be a residence fax number. This fax number will go to the provider who will convert the fax into a .pdf and email it to me. I will decide if it needs printing.
In addition, if I was to have foster children, then they will receive a telephone number. If they are not mature enough to have a cellular phone, then the phone number will go to their house phone which will be located in their bedroom. If they are expecting a telephone call, they can carry the wifi phone with them. This will teach them responsibility while they will learn how to use the phone properly. When they are ready, a cellular phone will be their primary device.
