Good now those operators get liberty not to pay BSNL till BSNL files a case and then for time that court gives verdict
This is just false propaganda by BSNL that private operators are not paying!
Well my friend i will explain you how this interconnect works. The controversy started because BSNL wanted operator's to pay higher carriage fees applicable for intra circle calls then what was agreed in the past. There are 2 parts towards the cost of termination of a call, 1) NLD Termination rate - 0.20/- per minute. This is fixed by TRAI 2) Carriage fees: The exact value is not fixed by TRAI and is left to operators to settle among themselves. This is only applicable when you are not terminating a call to that particular SDCA to which you are calling. Since its not possible or economical for pvt operators to interconnect with all the BSNL SDCA exchanges, they usually hand over the call to BSNL at limited locations and BSNL then takes that call over its own network. They now want pvt operators to pay more, and as per the pvt operators more than what was agreed in the past.
BSNL then blocked the private operators, who then approached TDSAT and got a verdict in their favor, which BSNL did not
honor. Its a simple case of BSNL running out of money and thinking of ways to collect more

Ever since the ADC (access deficit charge) has been removed, they are looking for non std means to increase revenue!
Myself being en EX- Vodafone employee who was taking care of interconnects has no way affected my nature of post i.e. calling BSNL's bluff!
