It’s no secret that Mukesh Ambani’s Reliance Jio has been at war with the Cellular Operators Association of India(COAI), which essentially means incumbent operators like Vodafone and Airtel, over points-of-interconnect(PoI).
Jio alleges that incumbent telecom companies are not allowing internet telephony calls to their networks by denying the requisite interconnection.
Jio claims that’s why calls from its network to other carriers and vice versa are not getting completed.
