We can’t be out of service for too long. Will there be much downtime if we change our system?

In many cases, we can install your new system while your old system is still up and running. We can transfer your lines and extensions to your new system and be up and running in a few minutes. Each install is unique and we perform a sight surveys to determine install time. TDLI will work with you and install systems after business hours and on weekends if needed.

We can’t afford too much capital outlay at this point. What are our payment options?

TDLI offers many payment choices; we offer one dollar buy out and fair market value leasing options with your choice of monthly terms, hosted and managed hosted solutions where you just pay per user per month, and we take all major credit card as well as company check or cash.

Can we get anything for our old system?

Because we repair and refurbish used equipment, in most cases TDLI can offer you cash for your old out of date equipment. We recycle and re-use what we can and responsibly dispose of what we can’t.

How do you handle ongoing maintenance and service issues? What is your response time if we have major problems?

TDLI maintains and supports everything we sell. You can call or email with simple user questions anytime. We offer extended warranty maintenance plans that cover the cost of equipment if it fails after the manufacturers warranty expires and a gauranteed 4 hour response time for major system failures. Our customers are entitled to one free service call every year and discounted service rates when they sign up for a maintenance plan.
