About Dave Fitterer

When a government agency’s phones go dark at 2 AM, it’s not just an outage — it’s a 911 call that doesn’t connect, a field officer who can’t reach dispatch. That’s the weight I carry every time I touch a network.I’m a Network Engineer with 20+ years in enterprise telecom, specializing in VoIP architecture, Cisco BroadWorks administration, Sonus/Ribbon Session Border Controllers (SBC), and SIP trunking for Public Sector clients. Currently with XO Communications (a Verizon partner), I design and maintain the voice infrastructure that keeps government agencies connected — reliably, securely, and without drama. I work entirely remote and am open to the right full-time or contract opportunity where deep telecom expertise is what the job actually requires.Over two decades, I’ve engineered voice networks where failure simply isn’t an option. From BroadWorks provisioning and SBC configuration to SIP troubleshooting across complex multi-vendor environments, I’ve kept mission-critical communications running for public sector organizations that depend on every call going through. I don’t just fix what’s broken — I build systems designed to stay up.I grew up on a farm in North Dakota, and that shaped how I work: show up, do it right, and stand behind it. I’m also a Viome Certified Nutrition Coach — which sounds like a left turn, but it reflects the same mindset I bring to engineering: precision, continuous learning, and long-term performance over quick fixes. If you’re building or maintaining a remote telecom team and need someone who’s done this at scale for government and enterprise clients, I’d welcome the conversation.
