The Carrier IP Telephony market continues to be highly dynamic, as service providers transition their real-time voice and video communications from the legacy circuit switch core network to the IP Multimedia Subsystem (IMS) core network.

To take advantage of the opportunities in this market, component manufacturers, equipment vendors, service providers, and financial institutions need to answer critical business questions including:

  • How will the IMS Core segment affect the market for fixed and mobile core equipment?
  • What happens to capital spending as Voice over LTE (VoLTE) services emerge?
  • How is vendor consolidation impacting the market?
  • How fast is the market for IMS core equipment transitioning away from circuit switch core equipment?
  • What impact does 5G have on the IMS Core market?
  • Who are the winners as the market transitions to Network Function Virtualization (NFV)?

To answer these and other important questions, Dell’Oro Group delivers both quarterly reports and 5-year forecasts on the Carrier IP Telephony market.
