The enterprise session border controller (SBC) market
grew 55 percent compared to 1Q10 as growth driven by strong adoption of SIP
trunk and hosted unified communications (UC) services, according to Exact
Ventures.

While Acme Packet leads both the Enterprise and Service
Provider segments of the SBC market, in 1Q11 its market share in the Enterprise
segment was half of its share of the Service Provider segment.  

Cisco continues to leverage its strong presence in the
enterprise IP PBX market for second position, while Ingate and Sipera, long
standing E-SBC and security focused vendors, round out the top four positions.

Beyond these vendors, the market for enterprise SBCs
remains fragmented, with perhaps 20 additional vendors vying for pieces of the
market. This fragmentation will work to provide strong competition,
driving prices downward.

Early market share is key because as the market grows,
economies of scale will help the larger vendors be aggressive on price as well
as to continue to fuel the research and development required to remain
competitive.  

We expect that as this occurs, the market will
consolidate,” said Greg Collins, founder and principal analyst at research
firm Exact Ventures.

In 1Q11, the market for IMS Core equipment contracted on
a sequential basis due to seasonal factors, but was up 20 percent compared to
1Q10, but accounted for just 3 percent of the total wireless and wireline NGN
Voice and IMS Core market, which is up from 2 percent in 1Q10.  Nokia
Siemens, Alcatel-Lucent, Ericsson, and Huawei, respectively led the IMS Core
market in 1Q11.
