Telecom equipment and solutions provider Ericsson remained number one in wireless voice core business. GENBAND maintained its
revenue share lead in the wireline voice core market.

The overall carrier IP telephony market revenues experienced a 10 percent
annual decline in the third quarter of 2011 as quarter-over-quarter growth in
the Voice Application Server (VAS) segment failed to offset declines in the
Media Gateway, Softswitch and Session Border Controller (SBC) segments.

Two areas of strengths in the market were evident: Voice Over Long Term
Evolution (VoLTE) infrastructure spending and, similar to last quarter,
business-focused VAS services.

“Based on recent interviews with vendors and service providers, we found
that 3Q11 was the first quarter of significant revenue recognition for IP
Multimedia Subsystem (IMS) equipment for LTE voice services,” said Chris
DePuy, analyst at Dell’Oro Group.

“It is exciting to see early signs that VoLTE infrastructure spending is
underway. While the services will initially focus on voice, we expect service
providers to offer new messaging and entertainment offerings to customers that
will compete with Over The Top services such as Skype.  We will be
watching for handset availability over the next year to confirm that VoLTE
services are rolling out as planned,”DePuy added.
