Since day one, Eyepea has been strategically focusing on Open Source technologies.
The Open Source model is indeed the only way to build solutions respecting the following criteria:

  • Low Cost of Ownership
  • Richness of functionality
  • Integration possibilities

Low Cost of Ownership: the hardware we use is standard server hardware from companies like HP or Dell and not expensive proprietary hardware from traditional PBX vendors. The software we use is mostly license-free as opposed to PBX vendors that charge you for every option/extension.

Richness of functionality: comparing the flexibility, extensibility and power of an Open Source VoIP Solution with a traditional PBX or contact center solution is somewhat akin to comparing a personal computer with a calculator. Our solutions offer an extremely advanced set of features only available in outrageously expensive systems.

Integration possibilities: the solutions we offer are completely open and their core is based on IT standards rather than telephony standards. Their integration with other applications within your company (CRM, ERP, Website...) offers an incredible richness of functionality.

Our offering is extensively leveraging the following Open Source projects:

  • Asterisk is a VoIP software platform that can be used for numerous applications.

    It is the world's leading open source IP-PBX, telephony engine, and telephony applications toolkit. Offering flexibility unheard of in the world of proprietary communications, Asterisk empowers developers and integrators to create advanced communication solutions.

    Its name comes from the asterisk symbol, "*". More information can be found on

    Eyepea and Asterisk:

    Asterisk is the basis of many deployments and developments done by Eyepea. We particularly appreciate the power, the flexibility and the openness of Asterisk.

    All the telecoms engineers of Eyepea have been certified on Asterisk (dCAP certification), proving of their competence.

    Eyepea is a regular contributor to the Asterisk project.

  • sipX ECS (Enterprise Communications Server) is an open source voice over IP-PBX platform best suited for large scale deployments.

    In contrast to its main open source competitor Asterisk, sipX does not
    play the role of a back-to-back user agent. This approach led to a modular and highly scalable system. All major components of sipX are implemented as servers and do not necessarily have to reside on a single
    machine only.

    Eyepea and sipX

    Eyepea selected sipX as its architecture makes it much more appropriate than Asterisk for large deployments where scalability and redundancy is key.

    sipXecs is used by Eyepea as platform for large enterprises or for service providers.

  • OpenSIPS (Open SIP Server) is a mature Open Source SIP server. With a very flexible and customizable routing engine, OpenSIPS 'unifies voice, video, IM and presence services in a highly efficient way, thanks to its scalable (modular) design.

    OpenSIPS is one of the fastest SIP servers, with a throughput that confirms it as a solution up to enterprise or carrier-grade class.
    OpenSIPS project is a continuation of the OpenSER project. Inheriting the OpenSER spirit of openness to the community and the will of progress (a continuous work to develop, enhance and extend the code), OpenSIPS continues and extends the OpenSER vision through a strong process of consolidation.

    OpenSIPS can be used as:

    • SIP registrar server
    • SIP router / proxy (lcr, dynamic routing, dialplan features)
    • SIP redirect server
    • SIP presence agent
    • SIP back-to-back User Agent
    • SIP IM server (chat and end-2-end IM)
    • SIP to SMS gateway (bidirectional)
    • SIP to XMPP gateway for presence and IM (bidirectional)
    • SIP load-balancer or dispatcher
    • SIP front end for gateways/asterisk
    • SIP NAT traversal unit
    • SIP application server
