Manual answering is when a fax has to be answered by an operator who presses a “receive” button.
The most common reason we hear about is that the fax machine shares a line with a regular phone line, and fax traffic is very light.
Instead of using a distinctive ring 2nd phone number, extra fax line, or other solution, some users prefer to be at the machine when it rings and presses “receive” if it sounds like a fax.
The challenge with manual receiving is that if the user is not there to press “receive,” the fax will not be received. Instead, the call will go to voicemail or not be answered.
