Inbound support operations

Volume doubles and your hold time doubles with it. It does not have to.

Zumu is AI inbound call handling for support teams that have run out of ways to add people. Every call gets answered in seconds, the questions you answer all day get answered from your own documentation, and the calls that need judgment reach a human who has already been told the whole story.

  • Every inbound call answered
  • Answers drawn from your own documents
  • Humans get the calls that need judgment
  • Supervisors can listen to any live call

Inbound calls are picked up rather than queued, so wait time stops tracking the volume curve.
Answered
Interruption-detection precision, measured in production. A caller who starts talking is not talked over.
86%
An escalation bridges your specialist into the same call, and a supervisor can still listen to the human leg.
In the room

There is no deflection rate on this page. We have not measured one across customers that would mean anything for your queue, and a number we cannot defend is worse than no number at all.

An operations floor at full volume

The pressure

Where the day goes on a support line

Three moments from a Tuesday on an inbound floor. None of them are caused by the people on it.

  • 09:02Tuesday

    The lines open and last night is already first in the queue.

    Everyone who could not get through yesterday calls again at nine. The first hour goes on apologising for the second call rather than resolving the first one, and the wait everyone hears at nine is the wait they will describe to a colleague later.

  • 11:30Tuesday

    Your most experienced person spends the morning on the easy ones.

    The same handful of questions arrive over and over: how do I reset it, where is my order, what does this code mean. The one person who could untangle the hard escalation is reading an answer she has already read twice this morning, and the hard escalation is holding.

  • 15:45Tuesday

    A caller who has already waited explains it all again to the specialist.

    The first agent collected the account number, the order reference and the symptom. None of it travelled. The specialist starts from nothing, the caller repeats herself, and a call that was already too long doubles. That is the moment support stops feeling like help.

Hold time is not a staffing shortfall. It is what happens when every call, easy or hard, has to pass through the same person.

How Zumu answers it

Four capabilities, aimed at the coupling between volume and wait

Each block is something the platform does today, pointed at one part of a support queue, and linked to the page that owns the mechanism.

  • In-room escalation

    Your people get the calls that need a person, and get them briefed

    Zumu does not stand in for your specialist. It gets the caller to her sooner and hands her a call she can start working immediately: the agent bridges her into the same room after saying who is calling, what they want, what has been checked and what is still open.

    Warm transfer with hold music while the agent writes 4 to 6 sentences on caller intent, facts collected, pending actions and verified details. Accept, decline or report voicemail, with cold transfer, voicemail, retry and hang up as fallbacks, and recording and live listen continuing through the handoff.

  • Knowledge graph

    The questions you answer all day, answered from your own documents

    Your help centre, your policy documents, your best call recordings. Point Zumu at them and it builds a knowledge graph the agents query mid-call, so the repeated questions stop reaching a person and the answers stay the ones you actually wrote.

    An eight-stage adversarial pipeline including a privacy-shield stage and a multi-model debate stage, written across a relational, graph and vector store, retrieved with hybrid dense and keyword ranking and a graph-aware path tried first.

  • Live supervision

    Coach the call that is happening, not the one in Friday’s review

    Your team lead watches every active call on one board, listens in without the caller knowing, sends the agent an instruction the caller never hears, and takes the call herself when that is the right call to make.

    A live wallboard over the active-call table with sentiment rebroadcast every 10 seconds, hidden listen-in that also works on post-transfer rooms, whisper limited to one message every 5 seconds, and barge-in behind an organization-level consent acknowledgement.

    Look at the supervision console

  • One agent, two doors

    The caller who gave up on the phone finds the same agent on your site

    The chat widget on your website runs the same agent, the same knowledge and the same escalation rules as the phone line, and your team takes a chat over from an inbox with one click. Nobody gets a worse answer for choosing the other door.

    One script tag, isolated inside a shadow root so it cannot inherit or break your site styles, with eight page tools behind confirmation dialogs, voice in the browser, and one-click human takeover from the support inbox.

    See the widget on a page

Nobody on your team loses a call worth having. They stop losing the day to the ones that were never worth a person.

What we can stand behind

In production for operators handling thousands of real inbound calls a week, on live phone lines rather than pilots.

The strongest thing we can say about inbound handling is not a percentage. It is that a supervisor can listen to any of those calls right now, including after one of their own people took it over.

86%
Interruption-detection precision, measured in production. It is the difference between an agent that waits and one that talks over your caller.
Every 10 seconds
Sentiment is rebroadcast to the wallboard for each active call, so a call going wrong is visible while it is still going.
Per call
One session report with the diarized transcript, the recording, the tool trace, the queue timing, the outcome and the exact cost.
English and Spanish
Live today, on a multilingual speech stack that supports 10+ languages.

No availability badge, no response-time badge and no deflection percentage. We measure plenty internally that is not ready to be a marketing claim, and until it is, this page stays quiet about it.

Questions

What support leaders ask before pointing a number at it

Still have questions?

Bring a call your queue lost. We will run the same conversation with you listening to both legs.

Two things, and neither is a promise that it never happens. The knowledge pipeline validates claims through a multi-model debate stage before anything is published to the graph your agents query, and retrieval is scoped to your documents rather than to the open internet. Underneath that, a deterministic detector counts more than 30 explicit escalation cues plus repeated tool failures and forces a handoff past a threshold. When the agent does not know, the design intent is to get you a person, not to improvise.
