The call failure rate (CFR) is the percentage of calls to an ISP or
any network provider that fail to get through. The CFR is commonly used as a statistical measure in
assessing Internet service providers. Companies can also measure the CFR for their own employees
who dial in for access to the company's network. Rating companies report on the CFRs for major ISPs
like AOL, Ameritech and Mindspring. Visual Networks, formerly Inverse Network Technology, is one
the best known benchmarking company of ISPs.
