The projected revenue represents a fivefold increase over the next 5 years.
According to the study, OTT application providers such as Skype and WhatsApp would experience a significant rise in traffic and revenue potential as 4G network rollouts accelerate, thereby increasing their capability to offer high-quality VoIP (Voice over IP) calls.
OTT Focus on New Revenue Streams
“As most mVoIP services were offered as a free or low cost service, only a small minority of OTT players had generated significant revenues from the service,” the study says.
It argued that the more successful service providers had developed indirect or adjacent revenues on the back of the core voice offerings, with a number offering in-app purchases or – as with Daum Kakao – a social networking platform.
Operators Fight Back
With the traditional operators’ voice revenues witnessing sharp decline as a result of OTT voice activity, a number of operators have adopted new business models mimicking those of OTT players.
“The new business models include directly offering functionality such as VoLTE (Voice over LTE) and Wi-Fi calling through the handset,” the study says.
The study also argued that white label OTT services, such as the fring alliance, are becoming increasingly important in helping operators compete with the OTT business model. However, it cautioned that such initiatives historically had mixed results, with both Telefonica’s TuMe and O2’s TuGo service having been discontinued.
Other key findings from the report include:
- VoLTE will see widespread adoption among MNOs, with operator billed VoLTE revenues approaching $100 billion by 2020, representing 12% of the global operator billed service revenue including voice and data services.
- HD voice adoption has been steadily rising since 2009, with over 130 operators worldwide offering Mobile HD Voice.
