Every PBX feature, hosted.
Extensions & Hunt Groups
3–5-digit internal dialing, ring strategies, simultaneous ring, and intercom across every site.
Visual IVR Builder
Multi-level menus with conditional branches, drag-and-drop editor, and one-click publish.
Smart Dial Plans
Working hours, holidays, after-hours voicemail, and calendar-aware DND per site. Supports STIR/SHAKEN call authentication standards.
Park, Page & Flip
Call park, flip between desk and mobile, call screening, and overhead paging site-wide.
Two weeks. Zero downtime.
Week 1
Port numbers & rebuild dial plan
Ringflow ports your numbers and rebuilds your dial plan in the visual builder — no CLI needed.
Week 2
Provision phones & run parallel
Desk phones and softphones provision automatically. Both systems run side-by-side with zero pressure.
Cutover
Flip the switch, keep the safety net
Go primary on Ringflow. Old system stays warm until you're confident — decommission on your timeline. Call recording activates on day one.
How It Works
Replace your PBX hardware in three steps.
Map your extensions
Import your existing extension list or build from scratch. Assign direct numbers, departments, and call permissions per user in minutes.
Build hunt groups and IVR menus
Use the visual drag-and-drop editor to create ring groups, sequential or simultaneous hunt logic, and multi-level auto-attendant menus.
Port your existing numbers over
Ringflow handles the full porting process. Most US numbers transfer in five to ten business days with zero downtime for your callers. Call recording and compliance features activate on the same day.
A PBX that doesn't live in a closet
Multi-site, multi-brand, drag-and-drop. Every feature your old PBX did — without the rack.
