Esna has been Acquired by Avaya
Acquisition accelerates communications-enabled applications for effortless engagement.

SANTA CLARA, CA - Avaya today announced it has completed the acquisition of Esna Technologies Inc. (Esna), a provider of real-time collaboration and communications software, to accelerate the adoption of communications-enabled applications for both enterprises and midmarket companies. Through the acquisition, Avaya will enable end-users to easily access multi-vendor communications capabilities – voice, video, IM/presence, conferencing and messaging – from within cloud-based business applications using their device of choice.

  • Will enable the integration of multi-vendor communications into cloud-based applications
  • Embedded, browser-based client will provide end users with one-click access to unified communications without leaving the applications or devices they are using
  • Will increase productivity and customer satisfaction through ease of use while reducing IT requirements for infrastructure and application deployment 

A tightly integrated, Esna-enabled Avaya Communicator web client will be available for both the Avaya IP Office® and Avaya Aura® platforms with out-of-the-box video and voice capabilities that can be embedded into public or private cloud-based business applications. The ‘headless’ thin client helps improve engagement, productivity and mobility by reducing the disruption caused by shifting in and out of applications or changing devices. For end customers, decreased effort in communicating with a company and improved experience of using multimodal ways to engage can lead to higher satisfaction, increased sales and faster resolution.
For IT departments, the flexible, open approach delivered by Avaya and Esna can allow their company to leverage their existing, multi-vendor communications infrastructure and easily integrate new technologies from Avaya and other vendors into cloud-based applications – an approach that can help companies avoid vendor lock-in. Further, a thin client can speed the introduction and adoption of new technologies for more successful deployments. Developers will be able to create new innovative web and mobile applications that are more dynamic and increase competitive differentiation.
Founded in 1989, Esna is headquartered in Richmond Hill, Ontario. The transaction includes the acquisition of intellectual property, assets, employees and customers of Esna. Esna is now a wholly-owned subsidiary of Avaya.
