A new Ookla study conducted in Manila compares voice performance over carrier VoLTE networks with over-the-top (OTT) voice applications. According to reporting from Business Line and The Hindu, the study’s findings indicate that carrier VoLTE delivers better voice quality and more consistent reliability than OTT alternatives in the tested conditions. The coverage emphasizes that the comparison is focused on measurable aspects of voice experience, including how well calls perform and how consistently the network handles voice traffic. Both outlets describe the results as showing that carrier-managed VoLTE services outperform OTT apps on the dimensions of call quality and reliability. While the two articles share the same headline framing and core conclusion, neither provides additional details in the supplied text on the specific methodology, sample sizes, app list, or exact performance metrics. The shared takeaway is that, in Manila, network-based carrier VoLTE performs more robustly for voice services than OTT apps during the study period.
