Who do you call when you need help on your system?

ISI's National Technical Assistance Center!

ISI offers support from our National Technical Assistance Center from 7 am to 7 pm Central Time, Monday thru Friday, under the terms of the Premium Service and Support Agreement. This Center can be reached via a toll-free number or by email and is staffed with certified technicians proficient in Windows operation systems, networking functions and the Infortel product lines. These technicians are available to handle "routine" questions as well as handle any problems that may arise through to resolution.

More than 98% of trouble tickets are resolved through remote diagnostic routines, which allow our technicians access to not only the Infortel software application but to buffer boxes, as well. Should the problem resolution require parts replacement, these are normally available within 24 hours. ISI also maintains a staff of Field Service Technicians, available for on-site visits, should the need arise.

The Customer Support section of our website offers a wealth of information, including Frequently Asked Questions, electronic Product Quick Reference Guides and more information about how to reach our National Technical Assistance Center.
