Can I use a fax with iPhone™ service?
A. In most cases the answer is Yes. The success is related to your internet speed connection, its quality and your fax machine. A fax requires 64K to function and many internet connection (Lite & Ultra Lite) variations do not provide constant speeds that a fax needs. We recommend that you have “full” high speed internet (1-3 Megs) for faxing. Your fax machine also plays a factor in its compatibility with internet based telephone services. There is no adjustment to be done on our part. You will just need to try.
