ESI In-House Phone Systems for SMB.

Small & Midsize Small Business Phones.

An ESI Communications Server is a powerful tool around which you can build your organization's entire telecommunications strategy and you don't have to know it all in advance. Technology Solutions specializes in helping you determine the best phone system for your organization and then installing and supporting your choice.


The ESI-100 or the ESI-50 can be a traditional digital business phone system, a fully standards-based IP telephony system, or any mix of the two. The choice is entirely yours, and the mix can easily change when your needs do.
