Our Services

Converged Solutions for the Modern Enterprise

At FSIT Networks, we believe that critical infrastructure requires specialized attention. We are not generalists; we are focused engineers dedicated to the convergence of Network Engineering and Unified Communications. While others treat Voice as just another application, we treat it as a precision ecosystem—optimizing your routing, switching, and security layers to ensure your communication platforms perform flawlessly.

Network Architecture & Design

A growing business needs a network that grows with it — not one that fights you every step. We design and document high-availability Cisco infrastructure built for where you're going, not just where you are.

Cisco Unified Communications

Voice issues are almost never just a phone problem. We specialize in complex Cisco UC environments — CUCM, CUBE, SIP trunking — and we fix what other engineers call too hard.

Specialist Consulting & Audits

Need a senior Cisco engineer without adding headcount? We embed with your IT team or MSP to audit environments, resolve escalations, and deliver the documentation that should have existed from day one.

What We’ve Delivered

  • "Multi-site UC deployment."

    Designed and deployed a multi-site Cisco Unified Communications environment for a 150-user organization across three locations — including CUCM cluster configuration, CUBE SIP trunk architecture, and full dial-plan documentation. Delivered on time with zero post-launch voice outages

  • "Network audit & remediation."

    Audited a 200-device Cisco network for a growing professional services firm — identified undocumented routing loops, misconfigured QoS policies, and missing redundancy paths. Delivered a full remediation plan and rebuilt the core architecture from the ground up.

  • "MSP escalation / specialist consulting."

    Brought in as a Cisco specialist by an MSP to resolve a long-standing SIP trunking issue their team couldn't crack. Diagnosed a CUBE misconfiguration causing intermittent call drops, implemented a fix, and delivered documentation the client's internal team could maintain going forward.
