Mid-Size Business VoIP Communication System
Our client, a mid-size business with multiple departments, was relying on legacy phone lines that were expensive to maintain and offered no visibility into call volume or routing efficiency.
The primary challenge was building a VoIP system that handled call routing and extensions across departments reliably, while giving management usable call analytics for the first time.
Without call data, management had no way to see which departments were overloaded or where call handling was falling short of expectations.

Challenge
Our client, a mid-size business with multiple departments, was relying on legacy phone lines that were expensive to maintain and offered no visibility into call volume or routing efficiency.
The primary challenge was building a VoIP system that handled call routing and extensions across departments reliably, while giving management usable call analytics for the first time.
Without call data, management had no way to see which departments were overloaded or where call handling was falling short of expectations.

Solution
Zyber Zing designed and deployed a VoIP communication system built on <strong>Asterisk</strong> and <strong>SIP trunking</strong>, replacing the client’s legacy phone lines.
A Node.js and PostgreSQL backend manages routing rules and extensions, giving administrators a way to make changes without contacting a vendor.
Call recording and a dedicated analytics service give management visibility into call volume and routing performance that the legacy system never provided.
Routing, recording, and analytics run as separate services, keeping call handling reliable even as reporting and admin features are used in parallel.

Department and extension-based call routing.
Call Recording
Recorded calls for training and quality review.
Call Analytics
Volume, duration, and routing reports for management.
Self-Service Admin
Manage extensions and routing without vendor calls.
Issue Alerts
Flags dropped calls and routing problems.
Lower Infrastructure Cost
VoIP replaces costlier legacy phone lines.
