D&S Communications is not now nor has ever been an authorized repair center for Polycom, Spectralink, Cisco or any other manufacturer. We provide third-party repair services for products manufactured by a number of companies. No products repaired by D&S are supported under the original manufacturer warranty. D&S provides our own warranty coverage for phones we repair. D&S makes no claims of affiliation or alliance with any of the manufacturers for the purposes of repairing their equipment.
