CX-E Interoperability

Do you have multiple vendors — Avaya, Cisco, Microsoft — all working together and playing an important role? Is the private, hybrid or public cloud in your future? Would you like it all to work together for a powerful, unified communications solution? There is one solution that offers it all.


Welcome to interoperability. CX-E is the industry’s most interoperable UC platform on the market because it works with what you already have. Now, your existing call control solutions, email systems, mobile devices, presence engines and data infrastructure can all work in harmony. No other UC platform offers a higher level of interoperability. CX-E allows you to make the most of your existing and future UC infrastructure — it’s UC your way.

Such interoperability doesn’t just happen by chance. Three decades of innovation and an extensive interoperability lab ensure a seamless connection to your existing and future communications landscape.
