Project overview.
A Unified School District needed to migrate 75 geographically distributed school sites from a legacy on-premises telephony platform to Cisco Webex Calling. PM2 NET delivered end-to-end professional services across readiness assessment, cutover planning, Webex Calling provisioning, service validation, issue remediation, and post-cutover stabilization. The project created a standardized, cloud-based unified communications environment with improved reliability, scalability, and service continuity across the district.
Client Background
The client is a Unified School District operating a highly distributed educational environment across 75 school sites. Reliable voice communication is essential for daily campus operations, administrative coordination, emergency response readiness, family communication, and staff collaboration. The district’s legacy on-premises telephony platform needed to be modernized to support future growth and cloud-based collaboration capabilities.

Challenge.
The district’s existing voice environment was built on a legacy on-premises telephony platform that had to be migrated to a modern cloud-native unified communications architecture. Because the district’s 75 sites were geographically distributed, the project required careful coordination, standardized deployment methods, and repeatable cutover processes.
Voice services are operationally critical in an education environment, so each migration had to be executed with minimal disruption. PM2 NET needed to validate network readiness, confirm call quality, coordinate PSTN number porting, align dial plans, transition users and devices, and verify service functionality after each cutover.
The project also required rigorous oversight to maintain consistency across all locations. Any site-specific exceptions, configuration issues, or service interruptions needed to be identified quickly, remediated efficiently, and used to refine subsequent migrations.
(03)
Result.
PM2 NET’s Professional Services Engineering team provided comprehensive delivery across the full migration lifecycle, using a disciplined and repeatable framework designed for a large multi-site education environment.
During the pre-migration readiness phase, PM2 NET performed network readiness assessments, including WAN/LAN capacity review, QoS validation, and firewall rule verification. The team also reviewed Session Border Controller configuration and completed interoperability validation to support a stable transition.
PM2 NET prepared the telephony environment by validating PSTN number porting readiness, aligning dial plans, and mapping users to the new platform. Webex Calling users, devices, and locations were pre-provisioned to support controlled site cutovers and reduce risk during migration windows.
For migration and cutover execution, PM2 NET created structured cutover plans with defined maintenance windows for each site. The team provided real-time remote engineering support during migrations and managed the controlled transition of users, devices, and DID ranges to Cisco Webex Calling.
After each cutover, PM2 NET performed feature and service validation. This included end-to-end call flow testing for internal calls and PSTN inbound and outbound calling, as well as voicemail, auto-attendant, hunt group, call routing, directory synchronization, and user experience validation. Performance monitoring was also used to confirm call quality and latency thresholds.
To maintain deployment consistency, PM2 NET used centralized issue tracking for site-specific exceptions and provided rapid root-cause analysis and remediation. A continuous feedback loop helped refine each subsequent site migration, improving efficiency and reducing risk across the full rollout.
Following cutover, PM2 NET completed final service validation, health checks, troubleshooting, escalation support when required, and confirmation of operational readiness before each site was signed off.
The Result
PM2 NET helped the district transition from a legacy on-premises telephony environment to a modern Cisco Webex Calling platform across 75 locations. The migration delivered high service availability with no unplanned outages, helping preserve uninterrupted communication throughout the transition.
The district gained standardized voice services across all school sites, improving operational consistency and simplifying long-term management. The new cloud-based UCaaS architecture also improved call reliability and created a more scalable foundation for future collaboration needs.
By using a controlled, repeatable migration framework, PM2 NET reduced operational risk and improved operational visibility across the project. The district now has a resilient, future-ready unified communications platform aligned with the evolving needs of modern education.
Key Outcomes
Migrated 75 school sites from legacy on-premises telephony to Cisco Webex Calling
Maintained high service availability with no unplanned outages
Standardized cloud-based voice services across all district locations
Validated call flows, voicemail, auto-attendants, hunt groups, routing, and user experience
Created a scalable UCaaS foundation for future collaboration and growth
