This white paper discusses the challenges of maintaining an internal fax infrastructure and argues that cloud-based fax services provide a lower-cost alternative. It notes that maintaining internal fax servers is costly, requiring significant spending on hardware, software, support personnel, and telecom providers globally. As IT budgets are cut, companies are reconsidering these costs. The paper predicts that the market for internet fax services will double from $750 million in 2008 to $1.5 billion by 2013 as more enterprises outsource fax to cloud providers and save money.
