The situation
This is the voice-specific workstream from the same global information services engagement documented in the Persistent Value Creation case study, scoped to $2,520,000 a year in in-scope voice spend across a disparate, legacy on-prem environment.
Why this was hard without help
A global voice transition affecting 23,000-plus users touches every region differently. PSTN needs vary by user and by geography, and legacy on-prem systems tend to carry years of oversubscription that nobody has gone back to correct, multiplied across a workforce this size, that's a meaningful hidden cost.
What Resourcive brought
A transition from disparate legacy on-prem voice to Microsoft Teams, grounded in user-level PSTN-need analysis that cut years of oversubscription rather than carrying it forward into the new platform. Multi-direct-routing partners covered APAC and EMEA, with implementation and service delivery managed throughout.
Results
Documented outcomes
- 49% spend reduction on the voice workstream, $1.2M in 1-year annualized savings.
- 23,000+ userstransitioned to Teams with regional direct-routing coverage.
- Years of oversubscription identified and corrected through user-level analysis.
Part of a larger engagement
This voice transformation was one of three workstreams in the same client's broader Persistent Value Creation engagement, alongside a colocation renewal and a China network redesign.
