Call Flow Builder
What happens when this number rings is a question somebody has to answer. You draw that answer yourself, walk a test call through it before a customer does, then publish it to the 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 branch you left dangling is caught before you publish rather than by the caller who takes it.
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.
A change you regret is one click back
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 lines we run ourselves.
Coach a rep mid-call without the customer hearing it, then join outright if it turns. Moving between the three never drops the call or rings anyone again.
Reps stop sitting through ring-outs. More lines open than you have people, paced off your live answer rate, and the abandonment cap you set is a ceiling.
Hand the tempo to the rep on one campaign and take it back on the next. Preview waits for them to read the record; power opens lines the moment they are free.
Reps stop greeting voicemail. The line is judged person or machine before a headset is involved, so what lands in one is somebody who said hello.
Stop the same two people carrying the floor. Six answers to who gets asked first, changed on the queue you already have rather than built again from scratch.
A caller reaches somebody who can actually help. Agents short of the skill a queue asks for never see the call, and a failover catches what nobody can take.
A caller presses a digit, hangs up and keeps their place in line. Repeat requests merge, so nobody rings the same person twice about one problem.
Your best account stops waiting behind everybody else. Flag the lead and they skip the welcome and the cap, while aging keeps ordinary callers from starving.
Nobody re-explains themselves to the next person. Send the call straight on, or speak privately first, or merge to three and walk out without ending it.
When a call is disputed, who said the line is read off its own channel rather than argued out of the wording. Both sides captured, merged into one file.
One code is the whole of a rep's paperwork. Twenty-six behaviors hang off it, so the task, the callback and the do-not-call mark happen on their own.
A rep never has to choose which of your numbers to call from. Every one they may use is scored against the person being dialed, and they can still override.
Buy the number and it already knows where to send its calls. Search live carrier inventory, filter by country or by the digits it ends with, then claim it.
One number reaches a whole country and the caller pays nothing for it. Toll-free routes through the same flows and bills from the same wallet as local lines.
Selling into a country you have no office in still means a number that looks local. Four carrier providers, so a new market is a purchase, not a project.
The extension is the person, not the device. One number reaches your rep, and a live call walks from browser tab to desk phone without either side noticing.
A call nobody was going to answer still lands somewhere. Organization, team and personal boxes each decide who may listen, and every message is transcribed.
Where a supervisor picks which call to join. Every conversation currently up, who is on it, the queue it came through and how long it has run, changing live.
Text from the numbers you already call on. The thread sits beside the calls to that contact rather than in a second app nobody on the floor ever opens.
Everything a caller hears that is not a person. Before you replace a prompt, the page names the menus, queues and mailboxes still playing the one you have.
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.
