Service Provider Voice Core Market Outlook is Stabilizing, Forecasts Dell'Oro

Voice over LTE and IP Multimedia Subsystem Are Growth Catalysts

REDWOOD CITY, Calif., Feb. 4, 2013

REDWOOD CITY, Calif., Feb. 4, 2013 /PRNewswire/ --Dell'Oro Group, the trusted
source for information about the networking and telecommunications industries,
reported that service provider voice core equipment spending over the next
five years is expected to remain approximately constant at nearly $7 billion
per year. This market has been in decline over the past five years. Growth
segments such as IP Multimedia Subsystem (IMS) Core, Voice Application Servers
and Session Border Controllers (SBC) are forecast to offset declines in mature
product segments such as Softswitch and Media Gateway.


"What has changed is that service providers are now offering commercial Voice
over LTE systems in Korea and the United States. The underlying IMS
architecture enables not just voice, but also messaging, file transfer, and
video calls. As service providers deploy these services, they will be more
effective in competing with Over-the-Top services that consumers purchase
directly with their smartphones," said Chris DePuy, Vice President at Dell'Oro
Group. "We expect to see a significant increase in IMS-based commercial
deployments over the next year," concluded DePuy.

Projections for the Session Border Controller market remain essentially
unchanged despite volatile results from some vendors in this market. The
forecast report also includes Voice over LTE (VoLTE) subscribers, IMS Core
equipment, Softswitch and Media Gateway equipment, and Enterprise Session
Border Controllers. Markets are covered for vendors such as Acme Packet,
Alcatel-Lucent, Broadsoft, GENBAND, Huawei, Metaswitch, Nokia-Siemens
Networks, Sonus, and ZTE.
