IP Multimedia Subsystem Core Revenues Grew Over 80% Year-Over-Year, According to Dell'Oro Group Beneficiaries Include Alcatel-Lucent, Ericsson, Huawei, Mavenir and Nokia Siemens

REDWOOD CITY, Calif., March 7, 2013 /PRNewswire/ -- Dell'Oro Group, the trusted source for market information about the networking and telecommunications industries, announced today that while the overall Carrier IP Telephony market revenues declined 5% versus the year-ago period, sales of IP Multimedia Subsystem (IMS) Core systems were through-the-roof.  IMS sales were driven by operator capital spending on current as well as planned launches of the new Voice Over Long Term Evolution (VoLTE) service.

"VoLTE is creating both opportunities and disruption in equipment spending patterns. We expect a significant increase in VoLTE services in 2013, with as many as twenty operators carrying native Internet Protocol voice from handsets by year-end," said analyst Chris DePuy.  "While IMS and Wireless Application Server spending accelerated in 2012, we expect further spending will be stimulated by the availability of VoLTE-capable handsets in the next several months.  Spending on certain wireline voice projects has been postponed as operators prioritize on wireless voice systems upgrades."

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 under $2 billion.
