ESI On-Premise IP Business Telephone Systems

​​Samsung IP telephone systems provide wired, wireless and mobility solutions via a 'Converged Communications  Platform.' These business phone systems provide a wide range of communication platforms that empower your business with access to voice and mobility solutions throughout your office complex and remote sites.​​ 

While the use of on-premise phone systems continues to stand the test of time, there are some applications in which a Cloud based or Hosted solution best meets the needs of a business, school or organization. 

A Cloud based solution uses the same technology as an on-premise IP system, utilizing a Local Area , Network (LAN) to power IP phones.  Rather than connecting them to an on-premise IP phone system, IP phones are connected through an Internet connection to a Cloud 

based provider. To help our customers who could benefit from such 

technology, we offer ESI's Cloud PBX business telephone solution. 

ESI systems deliver the benefit of a complete business telephone solution.  They merge the enhanced capabilities of an on-premise IP phone system with cost savings offered by cloud-based SIP trunks.  Gain benefit from, but minimize your dependence upon, the Cloud while maintaining local administrative control over your phone system.   If your company is not ready for SIP trunks for your local service (dial tone) ESI systems can support your analog phone lines until you are.
