REDWOOD CITY, Calif., May 15, 2013 /PRNewswire/ -- Dell'Oro Group, the trusted source for market information about the networking and telecommunications industries, announced today that while Carrier IP Telephony market revenues declined 19 percent overall versus the year-ago period, sales of IP Multimedia Subsystem (IMS) Core, Session Border Controller (SBC) and Voice Application Server (VAS) systems grew 10 percent. As Voice over Long Term Evolution (VoLTE) services has emerged as a major driver to the growth of these three products segments, another trend is starting – the virtualization of the telecom core.
"Service Providers have been pushing telecom equipment vendors to deliver software-based core networking functions in over the past several months," said Chris DePuy, Vice President of Carrier IP Telephony research at Dell'Oro Group. "A handful of vendors are prototyping control-plane oriented functions such as IMS Core and Voice Application Servers in response to customer demand. This important architectural shift is sure to re-shape the telecom landscape in the coming years."
The overall Carrier IP Telephony market, which includes devices used to serve both circuit switched subscribers and Voice over IP (VoIP) subscribers, reached revenues of just over $1.4 billion.
