The ESI eSIP Evolution Series™ is an award-winning on-premises phone solution that delivers the power, scalability, security and flexibility to optimize the communications of any business. A robust set of productivity-enhancing features put a world of control at the user’s fingertips. Advanced call handling options, built-in recording functions, conferencing and three-way calling, visual voicemail and many other easy to use features promote efficient user activity regardless of their role.
While compatible with the entire ESI ePhone line-up of enterprise phones, the rise of the modern distributed workforce demands that on-premises solutions can’t be tethered to only a desktop phone. The ESI eSIP Evolution Series™ offers users a desk phone (in-office or remote), a smartphone app, or a PC-based softphone to use without compromising quality or call handling options.
The power of the ESI eSIP Evolution Series™ comes from its industrial-grade Quad Core processors, T1 DSP voice processors, and extended-life power units; however, the solution’s strength doesn’t add to the complexity. The advanced plug-and-play capabilities, comprehensive auto-provisioning and a step-by-step online programming portal make it faster to deploy than many competitive on-premises solutions. Plus, enhanced disaster recovery options, built-in security with an internal firewall, and available monitoring and threat detection make this a reliable and resilient solution that your customers can depend on for years to come.
