TelecomLead reports that "OTT voice providers are expected to generate more than $10 billion in service revenues by 2020, representing a 5-fold increase over the next 5 years. Juniper Research said OTT application providers such as Skype and WhatsApp would experience a significant rise in traffic and revenue potential as 4G network roll-outs accelerate, increasing their capability to offer VoIP (voice over IP) calls.
As most mVoIP services were offered as a free or low cost service, a small minority of OTT players had generated a significant revenues from the service.
Because of sharp decline in voice revenues as a result of OTT voice activity, traditional operators have adopted new business models by offering functionality such as VoLTE (Voice over LTE) and Wi-Fi calling through the mobile handset"
