Voice over IP may be getting more attention right now, but fax over IP could be a quick, simple way to enter the VoIP network realm and save money in the process.
How extensively does your enterprise use fax among internal points? In some industries, such as health care, this can be a surprising amount of your traffic. I have seen 30% to 40% fax traffic among the offices of a multicenter health system.
When you look at your fax usage, also consider overnight delivery and courier usage and whether any can be replaced by quality fax. Remember that some documents, such as legal forms, must still be handled in physical form.
