VOIP Telephone Systems, Network Wiring and Technology Products

Cloud Hosted or On-Premise Solutions: We have it!

We offer communication systems from small to enterprise-sized businesses with 1 to 128 remote offices and between 5-10,000 users such as the Zultys "All In One" VOIP System that can be purchased as an appliance, or can be Hosted in the Cloud.  Either solution utilizes the same growing and evolving  feature set; Gigabit IP telephone units, and end user experience. Whether your employees are local or spread across the country.  If you have a phone system over 10 years old, it could very well be costing you more money to own than a new solution.  We can show you how to migrate to a modern solution customized for your organization.

Structured Tele-Data Network Wiring:

Do you have an expansion planned, putting up a new building, or are moving to another office suite?  Let us determine whether the current wiring plant is suitable or needs help.  Our staff installs structured wiring to ensure that your telephone equipment and data network function at optimum speeds and in an organized and neat manner. We are a licensed low voltage installer within the City of Syracuse. As a certified Hubbell premise wiring installer, ITS can provide a 25-year Hubbell warranty and can certify the cables with testing reports.
