Several years ago, when we were buying our first house, we had a fax machine. This made it very easy to send and receive the various paperwork for that process. Since we had voicemail on or main line, we could not leave the fax machine set up to receive faxes unattended. (The fax machine would answer the phone to see if it is a fax transmition, but if it wasn't there was no way to send the call back to voicemail.)
We solved this problem by having a second phone line installed, for the fax machine. This worked great, but became a waste when we were sending or receiving faxes. So we decided to cancel the second phone line, and sign up for a eFax number. This worked great, and eventually we signed up for an upgraded account, when we wanted a fax number in the same area code as our home number.
We periodically receive faxes, but never send faxes through it... Until this week. I needed to sign and fax some documents, and since we don't still have the fax machine, I was thinking that I would have to make a trip to Kinkos to fax these documents. But then I remembered that we have the new multi-function printer that has a scanner. This hadn't been set up yet, so this was a good opportunity.
