Voice and messaging traffic lost to over the top (OTT) players such as WhatsApp, Facebook and Skype will cost network operators $14 billion (€11 billion) in revenues globally this year, up by 26 per cent on 2013. According to latest research from Juniper Research, a number of markets including Italy, Spain and the UK have seen operator mobile voice revenues fall to less than 60 per cent of their value five years ago. The research suggests that a combination of IM, VoIP and social media substitution was primarily responsible, resulting not only in lost revenues but also in additional costs due to the scale of signalling traffic. However, new revenue streams could have the potential to deliver cumulative revenues to operators in excess of $66 billion over the next five years. Release
