The SIPfoundry user community is diverse and global and has one thing in common: The need to evolve an existing legacy (IP) PBX installation to a cost-effective, modern, all software IT application for all things communications. After 7 years of development starting in 2004, sipXecs has emerged as a comprehensive solution that offers voice, video, unified messaging, conferencing, instant messaging, presence, mobility and collaboration in one simple to install and easy to use application.

Among the sipXecs users are many smaller companies with between 50 and a few hundred users, often distributed over more than one location.  These companies like the simplicity by which they can self-administer the system, integrate with other applications, and improve their overall business processes bringing together different means of communications.

sipXecs has proven to scale and operate reliably up to about 10,000 user production installations.  Many large organizations start out with sipXecs as a pilot project trying to see whether it could be a viable solution to take the place of much more costly solutions.  In a Cisco CallManager environment sipXecs can be deployed alongside CM, providing a much more cost effective alternative that is easier and simpler to manage, that offers equivalent functionality. CM and sipXecs are connected over SIP trunks and CM users can access sipXecs provided services such as voicemail and conferencing.  For Avaya / Nortel customers sipXecs provides a natural evolution path from a legacy system.  Tested interoperability and the ability to even re-use Avaya / Nortel 1100 series IP phones provides compelling economics in support of a transition to sipXecs.  Try it out - there is nothing to loose. 

Social Business starts with communications

Presence enabled communication will change the way you communicate for ever. Software based communication and collaboration is an integral part of a modern IT environment and as enterprises transition from legacy telephony solution to software based communication and collaboration, the two worlds merge.  sipXecs is built to communications enable other IT applications, creating a truly unified and social environment.

Avaya / Nortel migration of the installed base

Still using an SL-100 Meridian-1 system or Communications Server 1000 (CS1000)?   Before the acquisition of Nortel by Avaya, the sipXecs technology was positioned as Nortel's straight line migration from legacy (IP) PBX solutions to a pure software based enterprise communications product.  You can trust sipXecs to perform well in providing a step-by-step migration with interoperability into the old world and investment protection along the way.

Cisco CallManager cap & grow

Started with a Cisco CallManager deployment and realized that extending CM to your entire enterprise might be cost prohibitive?   sipXecs provides equivalent functionality at significantly lower cost and interoperates with CM.  You can use sipXecs as a substitute for Unity voicemail and deploy sipXecs alongside CM with SIP trunking interop.  This has proven to be a winning solution saving significant cost without compromising user experience.

Microsoft environment looking for an OCS / Lync alternative

sipXecs has its background on the SIP Voice over IP (VoIP) side and provides a compelling alternative to an existing legacy (IP) PBX.  With its ability to integrate into the Microsoft environment, sipXecs is also a credible alternative to Microsoft OCS.  sipXecs integrates with Active Directory (AD), Exchange unified messaging, as well as Outlook.

sipXecs and commercial derivatives thereof are in widespread use.  It has been sold by Nortel and Avaya through channels such as Dell and IBM and it won TMC product of the year award in 2008.
