  5. Analyst Quotation “Increasingly, the enterprise market seeks communications servers that support voice and data convergence, and that are highly scaleable. In addition, an ‘all-in-one’ hardware solution with a single software interface that is capable of managing voice and data communications leads to greater ease of implementation, management and potentially lower operational costs. Any solution that combines these features merits attention.” — Jay Lassman, Research Director at Gartner

  27. Quote from Burton Group “We've been telling our clients that SIP is the key to truly open IP telephony solutions but there have been very few solutions available for the enterprise. Zultys Technologies is among the first to offer a trueSIP IP telephony solution with the features most enterprises require. Their product strategy is entirely based in SIP - starting with the MX1200 Enterprise Media Exchange - supporting voice, video, instant messaging, chat and presence capabilities that are interoperable with a range of other standards based SIP user agents and phones. The fact the MX1200 scales from 25 to 1200 users with fax, voice, video and data in one box, without additional hardware and only one software interface to manage it all, is also compelling for enterprise IT managers” —Ray Kaneipp, VP of Networks & Telecom Strategy
