Challenge

Their existing on-premises Cisco telephony infrastructure was complex, outdated, and spread across multiple global locations. This resulted in inconsistent user experiences, increased maintenance costs, and operational inefficiencies. Managing multiple systems also created challenges in scaling their communication solutions, hindered collaboration between global teams, and complicated compliance with security and regulatory requirements.

To minimise the impact to their operations, the client required a phased approach to transition basic telephony users to Microsoft Teams Phone System, with more complex scenarios and integrations planned for subsequent phases.

Solution

Natilik proposed a structured, three-phase solution to address the client’s needs:

  • 1.

    Discovery and pilot

    Natilik’s collaboration experts conducted a technology assessment covering telephony, security, and
    compliance, followed by a 40-user Microsoft Teams Pilot across four global locations to test system performance and user experience.

  • 2.

    Design and transition of basic users

    The Natilik team used Phase 1 insights to create a migration plan, transitioning users from Cisco telephony to Microsoft Teams Phone System, configuring the dial plan, and integrating Spectralink DECT.

  • 3.

    Complex scenarios and integrations

    Finally, the team handled advanced telephony needs, including Teams handsets, compliance recording, analogue devices, and SBC survivability. Conducted workshops, configured Cisco CUBE and Spectralink DECT, and provided testing and user training.

Outcome

The client achieved enhanced collaboration and communication by unifying their telephony system under Microsoft Teams, enabling global teams to seamlessly connect through a single platform for faster decision-making and more effective remote collaboration. The system was streamlined by consolidating multiple on-premises solutions into a centralised, cloud-based platform, simplifying management and offering flexibility to support future growth. Integration with Spectralink DECT ensured mobile users, such as on-site staff, stayed connected to Teams for real-time communication and improved responsiveness. A carefully structured, phased transition plan led by Natilik minimised disruption, ensuring continuous business operations while smoothly integrating new technology.
