Always answered

Never a missed call, never dead air.

The moment a call comes in, your agent picks up — no hold music, no voicemail, no waiting on a queue.

One agent, every shift

Always on, never overwhelmed.

The same agent works nights, handles the rush, and knows exactly when to bring a person in.

Works nights, weekends, holidays.

No shift changes and no burnout — the same agent answers at 3am as it does at 3pm.

Never buckles under volume.

Ten calls or ten thousand, every one gets answered instantly — no queue, no busy signal.

Initiates calls, not just answers them.

Follow-ups, feedback requests, appointment reminders — your agent reaches out on its own, no one has to ask.

The platform

Effortless to run, deeply
configurable voice agents.

Handle everyday requests and complex edge cases without trade-offs. Design the flow, pick the stack, and go live in weeks, not months.

01Call management and forwarding+
Route inbound calls by number, hours, or intent, and forward to a teammate the moment your agent needs a human, with full context carried over.
02Onboard existing phone numbers+
Bring the numbers you already have, no need to buy new ones or reprint marketing materials. Port in and go live without disrupting callers.
03Batch calling+
Launch outbound campaigns that respect your concurrency limits: start up to your slot limit, and the next queued call begins as one finishes.
04Follow-up calls+
Reminders, feedback requests, and no-show recovery go out on their own, on schedule, without anyone having to remember to make the call.
05Integrated experience+
Numbers, agents, and call analytics live in one platform, so nothing has to be stitched together across separate telephony and AI vendors.
Knowledge grounding

Answers from your data,
not guesses.

Upload PDFs and docs to a knowledge base. Voxvol chunks, embeds, and reranks in real time so your agent quotes the right policy on the right page, with the source attached to every call.

PDF ingestion

Drop in documents; we chunk, embed, and index automatically.

Vector search + rerank

Similarity thresholds and reranking for precise retrieval.

Source-cited answers

Every retrieval logs the document and page it came from.

Voice surveys

Ask how it went, right after the call.

Run NPS, CSAT, and CES surveys as a natural part of the conversation. The agent asks, adapts its follow-up to the score it hears, and scores every response automatically, no separate survey tool to wire up.

Adaptive follow-ups

Detractors and passives get a follow-up question; promoters don't waste time on one.

Send it your way

Trigger after a call, push via API, upload a CSV list, or run it on a recurring schedule.

Built to run at scale, and be governed.

Enterprise-grade controls, without needing an engineer on staff to run them.

One dashboard, every location

See and manage every branch, clinic, or store from a single login, no separate accounts to juggle per site.

Spending caps you control

Set a monthly limit per location. Calls pause instead of turning into a surprise bill at month's end.

Every call, recorded and searchable

Pull up any conversation for staff training, a customer dispute, or peace of mind, no digging through a call log.

Permissions that match your team

Front-desk staff see what they need to do their job; owners and managers see everything. No shared logins.

Reliability you don't have to think about

Built for real call volume with failover baked in, so a bad connection never turns into a missed customer.

Your data stays yours

Built on an open, auditable engine. Export everything and walk away any time, no lock-in, no black box.
