We start by extensively testing and evaluating the telephony product to see if it, in fact, needs to be repaired. If it does, then we take it apart, repair it, and, before reassembling it, test it again to make sure it's fully functional. And, unlike a lot of resellers, it’s not just a simple pass/fail tester we hook it to. Our facility has a complete switch test lab where we plug the products into working switches. This way, we know it’ll actually work in a real-world application.
