DGCA directs IndiGo to replace PW engines on 97 A320neo planes by 31 Jan


telecom regulator has ruled that an incoming voice call on a mobile phone must ring for at least 30

Operators would have to maintain the time duration of alert for an incoming voice call, which is neither answered nor rejected by the called party, to 30 seconds for cellular mobile telephone services, the Telecom Regulatory Authority of India (Trai) said on Friday. “However, originating network may release an unanswered call after 90 seconds in case the call release message is not received from the terminating network."


Airtel, the country’s second-largest operator by revenue, had in September said it had cut the ringing time for outgoing calls to a rival network to 25 seconds from 45.

Every second reduction on the ringing time saves spectrum resources for us," Mahipal Singh, associate vice-president of Jio, had said on 16 October in an open house held by the regulator. “94% calls on Jio’s network are answered within 25 seconds," he said, adding that the ringer time should be outside regulatory

While Bharti Airtel had said the ringing time be set at 45 seconds and argued that networks receiving the call must be allowed sufficient time, Jio had batted for a reduction to 20-25 

Rival Airtel, on the other hand, said the timer should be set based on the preference of the network which is receiving the phone call.

network should be allowed sufficient time to answer the call. This should be 45 seconds," Ravi Gandhi, chief regulatory officer, Bharti Airtel, had then said.

Also, every call that lands on a mobile network fetches it money. The interconnect usage charge or IUC is levied by mobile networks handling incoming calls from rival networks, and is a source of revenue for telcos such as Airtel and Vodafone Idea who enjoy

Jio, which reduced its outgoing call ringer time to 25 seconds, has more outgoing traffic than incoming. Jio’s outgoing traffic was 64% of its total voice traffic as of June end

Jio, however, has argued that globally, most operators have an average ringing time of only 15-20 seconds, and 25 seconds ringing time on Jio network is in line with global practice.

The reverse also has implications. Configuring duration of ringing time on lower side might save resources but may leaf to concerns over network performance
