Enterprise VoIP Modernization

445 Phones. Two Locations. Zero Business Disruption.

The problem

A leading sports and entertainment organization was operating on an aging Avaya VoIP system that no longer aligned with modern technology and security requirements. The outdated infrastructure created a growing need for modernization, from the underlying servers and voice gateways to the phones employees relied on every day.

With operations spanning a major entertainment arena and a warehouse fulfillment center, the challenge extended beyond replacing equipment. The organization needed a complete communications upgrade without disrupting daily business operations.

What we did

Acordis modernized the organization's voice environment with a Cisco-based solution, replacing legacy servers, voice gateways, SIP trunk infrastructure, and all 445 phones across both locations.

Our team configured the new hardware with current firmware, updated the supporting software, and applied security patches to bring the environment in line with modern security requirements.

To minimize disruption, all equipment was staged, configured, and tested before migration. The final cutover was carefully scheduled during off-hours, allowing the transition to take place without impacting users during business operations.

Acordis also provided user training to help employees become comfortable with the new Cisco phones and their enhanced capabilities.

Where it landed

The organization now operates on a modernized Cisco VoIP platform with updated software, current security patches, and enhanced phone functionality.

The transition was completed with zero business-hours downtime, providing a more secure, reliable, and capable communications foundation across both locations.

The result is a modern enterprise communications environment built to support daily operations and make collaboration easier for employees.
