ESI Communication Servers


ESI makes a wide array of powerful business phone systems which are essentially called communications servers. These servers allow businesses the flexibility to start small with a feature rich phone system for as few as 3-users at a single site and grow both the company and their phone system seamlessly as they change  into a large company with many branches.

 The ESI-1000, the ESI-600, the ESI-200, the ESI-100, or the ESI-50– can be deployed as traditional digital business phone systems,  fully functional-IP-based telephony systems, or any combination of the two. The choice is yours, and the systems can easily change when your needs change.

  • •Business phone system
