Hello! I’m Jonathan Marino — a Cisco VoIP & Unified Communications Engineer with over 12 years of experience designing, deploying, and optimizing enterprise voice systems. My focus is delivering scalable, secure, and high-performing communication solutions that help organizations stay connected across locations, teams, and time zones.

I specialize in the full Cisco UC suite, including CUCM, Unity, UCCX, Webex Calling, Cisco Expressway, IM & Presence, Jabber, and CUBE voice gateways. Whether I’m rolling out a multi-site Webex deployment or troubleshooting SIP trunking in a hybrid environment, I take pride in delivering results that are reliable, measurable, and aligned with business needs.

Throughout my career, I’ve worked in fast-paced environments where uptime and clarity matter. I’ve authored technical documentation, led UC upgrades from 10.x to 14.x, deployed secure MRA access for remote users, and supported 500+ endpoints with confidence and care.

My work is driven by a mix of technical precision and real-world collaboration — with clients, teams, and vendors alike. Outside of work, I stay close to the latest in voice, network, and cloud tech — always exploring new ways to simplify and elevate how people connect.

Thanks for visiting — feel free to check out my resume, projects, or get in touch.
