Mukesh Ambani-owned Jio has alleged that two crore calls between the two networks fail every day as Airtel has not provided adequate number of ports of interconnect (POI). Reliance also accused that Airtel's existing customers were not being allowed to shift to other networks and "urgent steps are required to be taken in the interest of customers of both operators", and said that last week, Airtel had agreed to increase the number of POIs only after "(telecom regulator) TRAI's intervention."
