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.

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.
