As mobile VoIP becomes more prevalent, organizations must ensure that their voice communications exhibit the carrier-class quality that the public switched telephone network (PSTN) has provided for many years. Call quality remains a high priority of CIOs to ensure that their entire organization remains productive outside of the office, able to effectively connect with partners, and serve customers without disruption. Low-quality calls discourage communication, thus affecting how well employees collaborate outside of the traditional office.

Maintaining high call quality becomes imperative as more calls are being transmitted via networks and protocols not built for carrier-class voice quality. In other words, inconsistent network conditions presented by wireless and VoIP technologies are becoming more prevalent in business voice communications.

To test how effectively the RingCentral solution maintains a high quality of service, ESG Lab tested voice connections in both normal and adverse conditions. ESG is an IT analyst, research, validation, and strategy firm that provides market intelligence and actionable insight to the global IT community.

RingCentral delivered great results!

According to ESG Lab report author and Senior Validation Analyst, Tony Palmer, the RingCentral platform achieved scores around 4.0 on a scale of 1.0 to 5.0, indicating good quality. Importantly, the scores remained in this range when ESG Lab simulated adverse conditions related to network congestion, packet loss, and jitter.

On this scale, 5.0 would be equivalent to a face-to-face, in-person conversation. Therefore, achieving a mean opinion score (MOS) in the 4.0 range under these conditions shows that RingCentral delivers high-quality voice communications consistently.
