  1. Bryan

    Purchasing the switch from Headsets direct was very easy. I had some questions about compatibility and called in they were very helpful. I have them the model number of the Cisco phone that I use and they not only confirmed the product was compatible they told me the settings that needed to be checked so I could easily use it right away
