Hotels, serviced residence, serviced offices, IT service providers, and any businesses that offer phone services require a call accounting system that gives them the flexibility to charge its customers and manage its suppliers. frSIP® integrated call accounting module allows you to capture all call charges whether it was a call forward, a call transfer, a call placed from a public terminal, or a call placed by the operator on behalf of a customer. Bill your customers in any way you want by having different tariff plans and call prefixes. Lower your cost and boost your profit with risk-free least cost routing that can fail-over to other suppliers in the event the cheapest provider is unable to process the call.
