Why Mobile Networks Answer Calls Differently

Root Cause: Asymmetric Interconnection agreements

The inconsistency in call answering across mobile networks, particularly between Reliance Jio and Bharti Airtel, stems from asymmetric interconnection agreements. Airtel’s interconnection points with Jio allocate only 50% capacity for Jio‑to‑Airtel calls, even though Airtel handles the majority of traffic. This imbalance leads to call drops and under‑utilised bandwidth, as Jio’s free‑calling service generates far more traffic than Airtel can accommodate.

Impact on Call Volume and Failures

Jio reported over 280 million call failures in a three-month period, while Airtel argued its infrastructure was adequate based on Jio’s forecasts. The dispute escalated to TRAI, which proposed penalties for Airtel, Idea, and Vodafone for alleged agreement violations. Jio cited under-preparedness by incumbents, whereas Airtel blamed Jio’s rapid subscriber growth for increased congestion.

Key Statistics

Business Implications and Mitigation Strategies

Asymmetric interconnection agreements can cause call drops, higher costs, and a poor customer experience. For outbound-calling operations and call centres, understanding these dynamics is essential when planning communication strategies.

How Cloud Telephony Helps

Cloud telephony provides a more reliable alternative to traditional telecom networks. By moving to cloud infrastructure, businesses can avoid many interconnection bottlenecks and gain features such as call analytics, predictive dialling, and AI-driven voice handling-all of which improve outbound efficiency and call-centre performance.
