Despite the myriad of challenges yet to be overcome, IP Telephony is no longer simply an interesting technology for early adopters and risk-takers, but rather a telecommunications solution with a great number of business advantages.

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:

• Will there be a wholesale conversion to Voice over IP (VoIP), as many industry pundits predict, or a long migration to this new technology?
• Will businesses rush to deploy IP phones to every employee?
• How quickly is the VoIP market growing and what trends influence its growth?
• Which equipment vendors lead the markets?
• How fast will IMS products (i.e., CSCF and HSS) displace NGN product sales?

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