If you think that this is being done for the consumer’s benefit, then you are wrong. The real reason is that the ring duration has an impact on the operator’s revenue. Here is how.
For example, if a Reliance Jio user calls an Airtel customer and Reliance Jio reduces the ringing time for outgoing calls to 20 seconds only, the calls may be cut off even before the Airtel customer has the time to pick it up.
Seeing the missed call, the Airtel customer calls back to Reliance Jio’s network.
So, for Reliance Jio, what started as an outgoing call, has been converted into an incoming call. In India, operators pay inter-operator fee, technically known as Interconnect Usage Charges. This charge is paid by the operator on whose network the call originates, to the operator on whose network the call terminates. So, in the above example, instead of Reliance Jio paying the fee, it now starts earning the fee, because of the shorter ring duration
Why the call ring duration matters to Airtel, RJio
