UCaaS · Call flow builder
Build call flows on a canvas — no code, no waiting
Most phone systems make you file a ticket to change how calls route. intSignal gives you a visual builder instead: drag blocks onto a canvas, connect them, and your call flow is live. IVR menus, ring groups, queues, business hours, conditions, AI agents and SMS actions are all blocks — assemble them like a flowchart, test with a simulated call, and publish in one click.
The canvas
Every routing decision, visible at a glance
See the whole caller journey as a diagram instead of a maze of settings buried in menus. Drag a block, draw a connection, and the path is defined. Because it's visual, anyone on your team can understand — and safely change — how calls flow.
Branch on real conditions: business hours and holidays, caller ID and area code, VIP or CRM status, language, wait time, or the outcome of an AI agent. No scripting required.
Confidence before you publish
Test the exact path before a real caller does
Run a simulated call through any flow and watch each step light up — greeting played, menu choice, queue reached, agent answered. The builder flags dead ends and unreachable branches before they ever hit a customer.
Ship safely
Publish in one click — roll back in one more
Every change is versioned. Publish when you're ready, and if something's off, restore the previous version instantly — no downtime, no re-building. See who changed what and when, so routing changes are auditable.
AI-assisted
Or just describe it, and let AI build the flow
Type “ring sales 9–5, send after-hours to voicemail, and text me when a VIP calls,” and the AI assembles the blocks for you on the canvas — ready to review, tweak, and publish. It's the fastest way to stand up a new flow or reshape an old one.
Plain-English to flow
Describe the outcome; AI lays out the blocks.
AI agent blocks
Drop a conversational AI agent into any branch.
Smart suggestions
The builder recommends fixes and better routing.
Editable, always
AI drafts a starting point — you stay in control.
