Voice core market to decline modestly


The service provider core voice equipment spending is
expected to decline at a 2 percent rate through 2015, according to Dell’Oro


While the majority of carrier voice equipment revenues is
expected to decline, the VoIP-only segment, which includes Voice Application
Servers (VAS), Session Border Controllers (SBC) and IP Multimedia Subsystem
(IMS) devices, is projected to grow over 20 percent annually.


Since 2002, spending on legacy equipment that connects
wireline circuit switched networks to new Voice-over-Internet-Protocol (VoIP)
networks has totalled to over $20 billion. This large worldwide investment
has resulted in widespread deployment of VoIP networks.


“We expect a robust growth of 43 percent in the
wireless VoIP-only market through 2015, as emerging high-speed wireless
networks experience voice upgrades,” said Chris DePuy, analyst at Dell’Oro Group.


“In addition, we expect so-called Over-The-Top (OTT)
services such as Skype and Google Voice to provide both challenges and
opportunities to the voice equipment industry during our forecast period.
Despite our expectation of a net loss of wireline subscribers over the next
five years, we expect the wireline VoIP-only segment to experience high
single-digit growth through 2015, driven by service provider upgrades to an all
IP network,” added DePuy.


The report also shows how Voice over LTE (VoLTE)
subscriber estimates and wireless VoIP-only 5-year revenue forecast relate to
each other in this high growth market.
