Once upon a time, I had three “full service” phone numbers, plus my mobile number. Two (including the mobile number) were used for business, another number for personal calls, and the last for faxing.
Faxes, of course, are yesterday’s news for the most part. But some companies and some individuals still use them, so I needed that capability. I also wanted to keep the other phone numbers active to separate personal and business activities.
But there was the cost of maintaining extra phone numbers, and I wanted to cut costs. My solution is as economical as I can make it without giving up those numbers and faxing capability.
