ITU model for the Calculation of Costs, Tariffs and Rates for Telephone Services
Negotiating tariffs or rates is a delicate matter, whether it is for a new operator entering a liberalized market or a regulator wishing to set affordable tariffs for national calls without compromising competitiveness among operators.
COSITU is a practical tool from ITU's Market, Economics and Finance Unit to automate:
the calculation of costs,
taxes related to the exchange of international traffic (accounting, settlement and termination rates),
interconnection rates between local operators, and
tariffs for national and international telephone services taking into account the impact of Universal Service Obligations decided by public authorities.
This model can be applied to both fixed and mobile services.
