VOIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet. If you have a reasonable quality Internet connection you can get business phone service delivered through your Internet connection with 702Ring.
How does VOIP work?
A way is required to turn analog phone signals into digital signals that can be sent over the Internet. This function can either be included into the phone itself (See: VOIP Phones) or in a separate box like an ATA.
