SIPfoundry sipXecs IP PBX Release 4.0 Addresses Mid-Enterprise Organizations With Cost-Effective Unified Communication Solution

Market share of open source IP PBX unified communications solutions continues to grow worldwide

WESTBOROUGH, MASSACHUSETTS--(Marketwire - June 23, 2009) - SIPfoundry (, a not-for-profit open source community, today announced a new major release of sipXecs, an open source enterprise IP PBX unified communications (UC) solution.

The SIPfoundry sipXecs IP PBX solution competes in the market for UC and IP PBX solution offerings as an open source alternative to traditional products from Cisco Inc., Avaya Inc., Shoretel Inc. and others. At times when budgets are tight and IT managers must think twice before committing to significant new purchases, system upgrades or expensive locked-in multi-year maintenance agreements, the sipXecs IP PBX solution represents a serious alternative that is cost-effective, fully open, interoperable and standards based.

The inherent flexibility of the sipXecs IP UC system makes it easy to offer a comprehensive unified experience to employees in virtually any organization as well as in collaboration with their partners and customers. This open software provides seamless integration with industry leading solutions, such as Microsoft Outlook, Active Directory, and Exchange, IBM Lotus and Sametime, Counterpath Bria and several other softphones. The native sipXecs UC capabilities are extensive and include capabilities such as unified messaging, click-to-call, find-me / follow-me, personal auto-attendant, personal conferencing, and support for high definition audio, real-time and intuitively easy-to-use communication using voice, video, instant messaging, conferencing and presence.

Release 4.0 of sipXecs adds critical new functionality, such as SIP trunking, Web Services (SOA), new collaborative applications and cluster management that bring a lower total cost of ownership to the organization.

With SIP trunking organizations have access to SIP services from Internet Service Providers (ITSPs) including BT, ATT, Bandtel,, Cbeyond, and even Skype. The SIP trunking gateway, now built into the sipXecs IP PBX replaces traditional Session Border Controllers (SBC) and offers all the necessary Network Address Translation (NAT) capabilities. The end result is a very cost-effective solution, combining low upfront cost with low operating cost.

The Web Services (SOA) open API for business process integration, a new conferencing application, seamless remote worker support, click-to-call capabilities, enhanced reporting, as well as significant enhancements and upgrades to the plug & play support for the many third party phones and gateways make this ideal for businesses today.

The new cluster management allows the deployment of a centrally managed, distributed sipXecs IP PBX system that provides both scale and redundancy - two critical mid-enterprise requirements. With the new capabilities introduced in release 4.0, the sipXecs IP PBX is now a good fit for both the SMB market (10 to 300 users), as well as the mid-enterprise and branch office market (150 to 10,000 users).

A commercial version of the SIPfoundry sipXecs IP PBX unified communications solution is available from Nortel ( under the brand name Software Communication System (SCS). It is sold with full commercial support through Nortel, as well as Dell, IBM, and other distribution partners worldwide.

The sipXecs IP PBX effort has experienced rapidly accelerating development and market acceptance, with many new developers joining the project over the past year.

Ease of use continues to be a hallmark of the sipXecs IP PBX solution. As many companies around the globe have experienced firsthand, sipXecs is simple to use and easy to install. Users quickly become self-sufficient significantly reducing IT expenses and technical training requirements. The Web management interface is extremely intuitive and the phone auto-discovery feature eliminates the complexity associated with IP phone configuration.
