Called New Residential Customers: Yes, I can convert Bus number to Residential; however, must be done through the Business side of the company. I learned that changing from Bus to Non-Residence service would only save me $10 +/- and that being the case, I may just as well wait until my advertising expieres (May 2013) and then decide.
I was also looking into adding a 3rd Cell Phone & number to my existing plan, but realized that there would be some degree of inconvenience since the phone would then have to be positioned centrally within the home for answering. Also, it would have to remain on "charger" 24/7. Although, it could be call forwarded when desired, too. And, if the power goes out, so does the cell phone whereas the landline will still work even if the power is off to the house/street, area, whatever. And, with a residential line I will have a listing in the telephone directory...I don't have one now except for the business number.
Decisions, decisions... Alas, my mind is being overburdened with what if's. Guess I stop and "smell the roses" and revisit at a later date.
Thanks everybody for you useful pointers.
