Are there any fax machines that work with internet phone service 100%?
No. The use of fax machines is seen by many as a “Dying Art form”. Many people have already started using “Fax to Email” type services. Not because of VOIP, but because they are on the road a lot, and don’t have carry fax machines with them. With more and more broadband, people are using scanners and sending jpegs and docs end to end. Things that need faxing are being emailed to a fax to email service which automatically converts the doc and faxes it to the other end. It’s more convenient, you can save the received docs, you don’t have to have or find a fax machine. If you are a VOIP user, and you really have to fax a lot, then you should look into a fax-to-email service. They aren’t that expensive each month. Then you don’t have any more problems. If you insist upon having a fax machine you will want to maintain a standard phone line for your fax machine and use your broadband phone service for your phone calls.
