In order to resolve this and create a more reliable connection some faxing protocols have been designed. Two such protocols are known as g.711 and T.38. When a service provider detects a fax signal, the appropriate protocol will automatically be used.

Most VoIP service providers do offer a fax service with a VoIP line. If you subscribe to a business VoIP package you will most likely get a free dedicated fax line as part of the package. If you subscribe to a normal residential VoIP package, then adding a fax line is usually an option available to you at an extra cost. The monthly fee for a fax line usually includes a limited number of minutes for sending out faxes, and unlimited minutes for receiving faxes. Obviously, you will need to pay for any outgoing faxes once you exceed your monthly free quota, although you will billed at a lower rate compared to regular fax charges.

Another setting which you may need to consider is the baud rate. Currently most VoIP providers provide support up to a 9600 baud rate, so you will need to adjust the baud setting on your fax machine or software.

Again, check with your VoIP service provider all the requirements for setting up a fax service.

Setting up the fax equipment is fairly simple. All you need to do is plug in your fax machine (or modem if using software) into an Analogue Telephone Adapter (ATA), which is in turn connected to your broadband modem. You can then send and receive faxes as normal.

If you do experience problems, you may need to double check your fax settings or consult with your Service Provider.
