Global Deployments & Managed Services: Zoom Phone for Multi-Site & Global Organizations (by GIS)

• You reduce incident variance by removing site-specific telephony rules and one-off configurations.
• You can roll out feature changes and security updates globally with one playbook and one calendar.
• You gain clear ownership for moves, adds and changes instead of shared responsibility across sites.
• You simplify vendor management by routing most voice issues through a single managed services partner.

Central IT defines one global dial plan, numbering scheme and call routing model that every site must use. A managed services provider configures Zoom Phone, handles carrier relationships and runs standardized change, and incident processes. Local offices give up direct control of trunks, carriers and PBX rules, and instead submit requests into a single queue with defined SLAs. Runbooks, topology diagrams and inventories are maintained centrally, and updated when a site is added, moved or reconfigured. Reporting is pulled from one global dashboard, not stitched from multiple regional systems.

This week, list your current telephony contracts and site-specific dial plans.

• Map current sites, carriers and PBX configurations into a single inventory.
• Define a draft global dial plan, numbering scheme and call routing policy.
• Assign one accountable owner for global voice operations and escalation.
• Engage a managed services partner to validate the design and propose a phased migration plan.
