    I have over a decade of VoIP networking experience deploying and configuring iPBX's (3CX, ShoreTel), Skype for Business/Lync, Session Border Controllers and Gateways (AudioCodes, Sonus, Edgewater). My experience ranges from complete project management to individual SBC/GW implementations. My core focus has been VoIP connectivity and the applications that accompany it like Call Recording (Cloud & On-Premise), Office 365 and Exchange. The vast majority of my time has been spent implementing on-premise systems (60%) and hosted systems (40%) for small and medium businesses. I have interfaced with Tier-1 Carriers, (ATT, Verizon, Centurylink, Level(3)) all the way down to pure SIP based service providers such as (G12, Flowroute, PureIP).
