Market research firm Infonetics Research released excerpts from its new Mobile VoIP Services and Subscribers report, which tracks native mobile voice over IP (a.k.a. voice over Long Term Evolution, or VoLTE) and over-the-top (OTT) mVoIP service revenue, subscribers, and deployments by world region.Â
 “The adoption of over-the-top (OTT) mobile VoIP services is growing rapidly but it is not without challenges. With free applications and extremely low revenue from users, it is tricky for application providers without the deep pockets of larger companies like Google, Microsoft, and Telefónica to have a sustainable long-term business model. Despite the fact that we expect mobile VoIP subscribers to grow nearly 10-fold from 2010 to 2015, there is relatively little money to be made from it in the near term,” poses Diane Myers, directing analyst for VoIP and IMS at Infonetics Research.
Stéphane Téral, Infonetics Research’s principal analyst for mobile infrastructure, adds: “As LTE becomes the universal mobile infrastructure, TDM voice – which is a $500 billion-a-year business – will migrate to VoLTE (native mobile VoIP). In the near term, though, two key challenges need to be addressed: the world needs widely available LTE handsets that support VoLTE – and we’re nowhere near that stage – and Single Radio Voice Call Continuity (SRVCC) needs to be finalized so that voice calls work seamlessly between LTE and legacy networks. Make no mistake: VoLTE is the future; it will just take many years to get there.”
