Zoom Phone & UCaaS Leadership (by GIS): Zoom Phone Migration by GIS (Immediate Cost Savings)

Finance and operations leaders are treating the move to Zoom Phone as a near-term cost control lever, not a long-term infrastructure project. The shift is from fragmented carrier contracts and PBX maintenance to a single, metered UCaaS line item that finance can model within current planning cycles. This requires IT, workplace and finance to align on which call flows, sites can migrate immediately for savings, and which require phased change. The opportunity is to swap fixed voice costs for a usage-based model you can forecast with current usage and invoices.

• Reduces overlapping spend on legacy voice circuits, maintenance and underused licenses within the current fiscal year.
• Simplifies budgeting by turning multiple carrier and support contracts into a single predictable service line.
• Improves meeting and call reliability by running voice on the same platform already used for conferencing.
• Gives finance clean, auditable usage data to refine automated forecasting models for communications spend.

Teams stop treating telephony and meetings as separate projects, design one consolidated call, and meeting environment around Zoom. IT maps current DIDs, hunt groups and critical lines, then tags them as immediate migration, phased migration or hold. Workplace teams coordinate device needs, porting windows and user change impact per site. Finance plugs the proposed Zoom Phone footprint and calling patterns into their models, replacing assumptions with current usage and carrier invoices. Support owners update runbooks so every call issue, number change or routing adjustment has a clear path and a single platform to troubleshoot.

This week, pull the latest carrier invoice for your highest-cost location and note the top three cost drivers for a Zoom Phone migration sketch.

• Collect carrier, PBX maintenance and conferencing invoices for the last six months.
• Export current Zoom usage data for voice-related traffic and meeting density by site.
• Group all phone numbers and call queues by business criticality and migration readiness.
• Schedule a working session with GIS to validate a phased Zoom Phone cutover plan with quantified savings.
