"Voice services are viewed as an essential service by operators and their customers, despite increased demand for data-oriented services," said Chris DePuy, Vice President at Dell'Oro Group. "As high-speed LTE networks are now reaching broad coverage in many regions, and wider availability of VoLTE handsets are expected later in 2013, we expect to see significant subscriber growth in these networks," concluded DePuy.

The forecast report also includes Voice over LTE (VoLTE) subscribers, IMS Core equipment, Softswitch and Media Gateway equipment, and Enterprise Session Border Controllers.
