PBX Management

Managed PBX operations—extensions, trunks, IVR tweaks, and health checks on a monthly plan.

PBX Management covers day-to-day PBX operations after go-live: extension changes, trunk adjustments, IVR tweaks within capacity, and health monitoring review. Ideal when your business phone system needs a steady operator rather than a project every time someone joins.

From $149 / seat / month

Who it’s for

  • SMBs and mid-market teams on FusionPBX / Asterisk-class PBXs

  • Companies after a PBX deployment needing continuity

Problems we address

  • Extension and ring-group changes backlog for weeks
  • IVR updates require hunting for the original installer
  • Trunk issues surface only when calls fail
