CAMPBELL, CA--(MARKET WIRE)--Jul 23, 2008 -- A new study by Infonetics Research that provides a broad view of service provider thinking and plans for voice over IP, including service provider perceptions of leading VoIP vendors, names Acme Packet, Alcatel-Lucent, Cisco, and Sonus as the "top VoIP equipment manufacturers," with Cisco emerging as the most familiar manufacturer.

According to the study, Service Provider Plans for VoIP, which surveyed service providers in North America, Europe, Asia Pacific, and Latin America-Caribbean, the top 3 technical challenges these carriers face are competition, migration to IMS, and capex reduction.

"Service providers are operating in a capped capex environment now -- meaning, generally they purchase equipment only when they need it. There are some areas in which most carriers are increasing their capex, though: growth areas tied to additional revenue, such as VoIP," said Stéphane Téral, principal analyst at Infonetics for service provider VoIP, IMS, and mobile infrastructure.

The study is based on formal interviews conducted by Infonetics' senior analysts with incumbents, IXCs, competitive operators, vertically integrated service providers, and specialists. The 85-page study examines the trends, drivers, barriers, and implementation plans of VoIP service providers, and features VoIP network architecture plans, a VoIP vendor scorecard, and service provider feature wish-lists for VoIP products, including trunk media gateways, softswitches, voice application servers, media servers, and session border controllers.

Other highlights from the study:

 
--  40% of respondent service providers don't plan to complete their
    migration to Class 4/tandem switching until after 2009, suggesting they
    have enough capacity to handle international voice traffic growth
--  The top retail VoIP service offered by service providers to their
    residential and business customers is voice over broadband
--  In a series of questions asking service providers to rate Alcatel-
    Lucent, Cisco, Ericsson, Huawei, Nokia Siemens, Nortel, and Sonus, those
    familiar with the vendors rated Sonus highest for technology, product
    roadmap, security, management, and price-to-performance ratio
--  55% of respondents have already installed Acme Packet's session border
    controllers
