Call Flow Builder
A call flow is the answer to 'what happens when this number rings'. You draw it: thirty-nine nodes across compliance, routing, identity and CRM, connected on a canvas, dry-run before anyone else sees it, then published to a number.

How it works.
Drag the path a call takes
Nodes come off a palette grouped by what they do: play audio, ask a question, check a list, look up a record, send the call somewhere. You connect the outputs, and a node with an unconnected branch is flagged before you can publish.
Dry-run it before anyone hears it
Press test call and a simulated caller walks the graph in front of you, lighting each node it enters and taking the branch the conditions actually resolve to. Wrong turns are visible on the canvas rather than reported by a customer.
Publish to a version, not over the top
Publishing freezes the flow as a numbered version and points the number at it. Calls already in progress finish on the version they started, and rolling back is selecting the previous one.
Point any number at it
A published flow is a destination. Any number you own can be pointed at it, several numbers can share one, and changing which flow a number uses takes effect on the next call.
One moment in every call.
Every call passes through the same seven. Call Flow Builder is the lit one, and everything either side of it is a different page in this category.
- 01Number
the line it arrives on or leaves from
- 02Route
where the call is sent and to whom
- 03Dial
placing it, and how many at once
- 04Connect
the moment a person picks up
- 05Talk
while the conversation is happening
- 06Wrap
the code, the notes, the next step
- 07Record
what is kept, and where it is kept
The specifics.
7 facts- Nodes
- 39, across compliance, routing, identity, audio, logic, CRM, AI, messaging and control
- Templates
- 15 starting points, including auto-attendant, support queue and after-hours
- Versioning
- Every publish is a numbered version; in-flight calls finish on theirs
- Validation
- Unconnected branches and unreachable nodes block a publish
- Testing
- Simulated call walks the live graph, lighting each node it enters
- Reuse
- Send-to-flow lets one flow call another, so a shared greeting is written once
- Scope
- The same graph serves inbound calls and calls another system asks for
Where the call goes next.
A call is a chain of decisions, and this is one link in it. These are the ones either side.

20 capabilitiesFlows, queues, oversight and compliance screening on media we operate.
Three states of one connection. Hear the call, coach the rep without the customer knowing, or join outright - and the audio path redraws as you switch.
Open more lines than you have reps, paced against live answer rates, and hold the abandonment cap you set. Every connect opens the record it belongs to.
Set the mode per campaign. Preview lets a rep read the record first, autodial moves on after wrap-up, and power opens several lines per agent.
Detection listens to the first moments of a connect and drops greetings, dead air and IVR trees. What lands in a headset is a person who said hello.
Ring all, hunt, fewest calls, random, round robin with memory, or strict priority order. Change how a queue behaves without rebuilding it.
Match a caller to the agents who can actually help, on all, any or weighted skill matching, with a failover destination when nobody qualifies.
Offer a callback after a wait threshold or a queue position, hold the caller's place, and dedupe requests so nobody gets rung twice for one problem.
Flag a lead VIP and they skip the welcome, bypass the queue cap and reach an agent first - with ageing, so that ordinary callers never starve behind them.
Hand a call over cold, or consult first and then connect. Merge into a three-way and step out, leaving the other two talking without a drop.
Each side of the call is recorded on its own channel, so who said what is a fact rather than a guess - and the transcript inherits that separation.
Wrap-up codes that do something. Twenty-six behaviours fire off a disposition: raise a task, book a callback, set do-not-call, flag the wrong party.
The number most likely to be answered is chosen per call, ranked on the history with this lead, the overall answer rate, recency and area-code affinity.
Search live carrier inventory, filter by country or by digits the number ends with, and claim it to a flow or a person the moment it is yours.
Toll-free sits beside local as a first-class number type, routed by the same flows and billed from the same wallet as everything else you own.
Numbers in the countries you operate in, drawn from four carrier providers, so opening a new market is a purchase rather than a procurement project.
Every rep gets an extension and a browser phone, and can move a call between the browser and a desk phone mid-conversation without dropping it.
Organisation, team and personal mailboxes with their own access rules and greetings, and every message transcribed and attached to the right record.
Every call in progress on one screen, pushed as it changes rather than polled, with the agent, the number presented and the queue each one came through.
Two-way texting from the same numbers you call on, threaded per contact and landing on the same record, so the text and the call are one conversation.
Upload a recording, record one in the browser, or generate it from text in a chosen brand voice - then use it in any flow, queue or mailbox.
The rest of the platform.
Five more categories, all on the same record and the same bill. Each card names three of its capabilities, so you can tell from here whether it is worth opening.
