Understanding Business Drivers for VoLTE: Dialable VoIP and VAS vs. OTT Voice Services

With increasing awareness of IP as a cheap source of transport, more people are aware of VoIP and OTT alternatives

There are many reasons for justifying Voice over LTE (VoLTE) beyond the obvious efficiencies for voice services.  Some of the business case drivers include:

  • Revenue retention
  • Preparation/foundation for RCS
  • HDTV and HD voice services
  • Next Generation Apps (Augmented Reality and others)
  • Small carrier opportunities (roamers and vacation spots)

Arguably, the biggest driver is simply “Dialable VoIP”.
