I have 2 phones, and 1 fax machine. The fax machine is my home network printer which has faxing capabilities. More information on the printer can be found on the Printers Page. The reason for two phones is to have 2 phone lines, one for the home and one cellular.
The home phone is an Ooma HD3 cordless handset which is connected to an Ooma Premiere account. The phone has a color LCD screen to show actions, and act as a CID unit. The phone contacts are added through the management website.
The second phone is my Pixel 3a XL which hosts my cellular phone line with Google Fi. This is the number that most people know, and the one that I had the longest. This is the telephone line that is on my contact cards, but all phone lines are on my contact directory.
