Predictive dialing engine, explainable by design.
Pace calls by agent availability, answer-machine probability, and queue health. Every decision is logged as a signal you can inspect, replay, and tune — not a black box.
Sigma Dialer is the predictive dialer, inbound ACD, compliance layer, and agent desktop — unified in one remote-ready platform that any team can deploy in an afternoon. No on-prem boxes. No surprise bills. No dropped calls.
Native connectors, webhooks, and an open API. If it has an endpoint, Sigma talks to it.
Sigma replaces five tools: dialer, telephony, WebRTC softphone, compliance engine, and analytics. Every lead goes through the same event bus — so every decision your dialer makes is explainable, auditable, and tunable in real time.
Pace calls by agent availability, answer-machine probability, and queue health. Every decision is logged as a signal you can inspect, replay, and tune — not a black box.
TCPA windows, state-level calling curfews, federal + internal DNC lists, consent logging and call recording disclosure — evaluated per call, in milliseconds, before the number ever dials.
Agents dial from Chrome. No headset drivers, no VPN, no IT ticket. Crystal-clear Opus audio with adaptive jitter buffering.
Automatic local caller ID, region-matched voice routing, and calling-window enforcement down to the ZIP code.
Queue depth, SL, abandon, contact rate, agent state — streamed to your wallboard with sub-second latency.
Dynamic scripts that adapt to answers in real time. Objection handling, disclosures, and dispositions in one pane.
Skills-based routing, visual IVR builder, callback-in-queue, and whisper transfer. Inbound and outbound on one stack.
Every call transcribed, summarized, and scored. Flag risk phrases, coachable moments, and winning talk tracks.
Stream every call event to your CRM, warehouse, or custom ops tooling. Native Salesforce, HubSpot, Zendesk.
A real deploy, not a six-week "implementation." Bring a list, invite your agents, connect your CRM, and go live. Our team sits with you on launch day.
Native Salesforce, HubSpot, Zendesk, Pipedrive — or hit our REST API. Bidirectional sync out of the box.
Drop a CSV or stream from your warehouse. DNC and TCPA checks run automatically before the first dial.
Agents log in from any browser. Zero install. Role-based permissions scoped to campaigns, queues, and geos.
Watch the wallboard. Tune pacing. Ship a/b-tested scripts. Sigma writes every signal to your data warehouse nightly.
One event bus from the moment a lead lands in the queue to the moment a disposition writes back to your CRM. Every stage is inspectable, replayable, and hot-swappable without redeploying.
Real-time transcription, automatic summarization, risk-phrase detection, and coaching insight on every call — not just the ones someone remembered to QA. Feeds back into the pacer so winning tracks get surfaced automatically.
Hi Priya, thanks for picking up — I'm Ana from Sigma. Is now a decent moment for two minutes?
Um, I'm on my way out in a sec, but yeah — go ahead.objection · time
Got it, I'll be quick. You renewed last October; I wanted to flag a better plan that's saved folks in your tier about 18%.
Hmm. Last time I was told the same thing and the fee didn't actually change.risk · trust
That's fair — let me pull up your account and walk through the exact line items so you can see the delta before committing to anything.
Okay. Send that over.
We killed three vendors the week we turned Sigma on. Our agents dial 2.4× more conversations and compliance finally stopped waking me up.
The explainable pacing is the killer feature. When a campaign underperforms, I can actually see why — not file a ticket with a vendor for a week.
We launched on Sigma from a cold start in six hours. My old platform took a fiscal quarter, two consultants, and a rack of servers.

Ops runs the floor. Compliance carries the risk. IT owns the stack. Sigma is the rare tool all three actually agree on.
Most teams place their first live call on day one. A named launch engineer sits with you for onboarding and porting existing numbers typically takes 3–7 business days on the carrier side.
Yes. Every dial runs through the TCPA Guard: consent check, calling-window evaluation by jurisdiction, recording disclosure, and full audit logging. You own the consent records; we make sure they're actually respected.
A tier-one carrier mesh with active failover across four providers. STIR/SHAKEN signing on every outbound call, plus automated reputation monitoring and number rotation when a caller ID starts degrading.
