Kolkata: The Telecom Regulatory Authority of India (TRAI) plans to bar full-mobility telecom service providers (GSM or CDMA-based) from preferance or exclusive outgoing call charges within their own networks. They will be required to offer the same outgoing rate to terminate calls on rival full-mobility networks

Once a full-mobility service provider decides on a particular outgoing tariff, it will have to offer the same rate to terminate all outbound call traffic to any rival full-mobility network.
