An AI dialer is software where an AI voice bot places the outbound call and handles the conversation, so no human rep dials or waits on the line. VoiceOI is an AI auto dialer for call centers: it works through a lead list, detects answering machines, qualifies whoever picks up, and live-transfers qualified leads to a human closer.
Dialers differ in who talks to the person who answers. A traditional auto dialer only connects the call to a rep; an AI auto dialer also holds the conversation. Vendors define power and progressive dialing differently, so the rows below describe the common pattern. Our guide to types of call center dialers quotes how Genesys, Five9, Regal, Dialpad and Mitel each define them.
| Dialing mode | How it dials | Who handles the answered call | Best for |
|---|---|---|---|
| Traditional auto dialer | Works through a list automatically, so nobody dials by hand, and connects each answered call. | A human rep | Teams that want to stop dialing numbers manually. |
| Predictive dialer | Dials several numbers per available rep, using an algorithm to guess when reps will be free. | A human rep | Large teams of reps working big lists, where keeping reps busy matters most. |
| Power dialer | Places calls when a rep is ready, often at a fixed ratio of lines per rep that the manager sets. Definitions vary by vendor. | A human rep | Small and mid-size sales teams that want a steady pace without guesswork. |
| Progressive dialer | Places the next call when a rep is available. Some vendors dial one number per free rep, some use a preset ratio and some add a preview step. | A human rep | Teams that want to see lead details before each call. |
| Voice broadcast | Plays one prerecorded message to many numbers at once. | Nobody: a one-way message, with no conversation | Notices and announcements, where no reply is needed. |
| AI voice bot dialer (VoiceOI) | Each bot places one call at a time from a lead list. Add bots to run more calls at once. | The AI voice bot, which qualifies the person and live-transfers the call to a human closer when they qualify. | Call centers that want the first-contact (fronter) work done by AI and the closing done by people. |
VoiceOI is in the last row only. It does not pace calls for human reps; see the limits below, and the AI telemarketing software page for how AI sits next to a rep-based floor.
From a loaded lead list to a logged outcome, with no rep dialing.
Upload a CSV lead list, or keep your lists in VICIdial. Filter by state, area code or ZIP code, then set calling windows and retries.
Each bot places one call at a time. Voicemail greetings and other machines are detected, and the call ends without leaving a message.
After your optional AI-voice disclosure, the bot asks the questions you built in the no-code script builder and branches on each answer.
Qualified leads are handed over SIP to a closer. Every other call ends with a disposition, a recording and a transcript.
You do not need VICIdial to run an AI auto dialer with VoiceOI. The built-in dialer runs bot campaigns directly: you upload a lead list, pick a carrier, set the pacing in the campaign manager for outbound bots and press start, then watch calls in a realtime view.
Carriers connect over SIP. Paste your carrier's sip.conf or pjsip.conf block into the Carrier Manager and bots dial through it, whether that is a Twilio SIP trunk, a Telnyx SIP trunk or any other SIP trunk for AI voice agents. Dialing and the transfer run over that SIP trunk.
If your floor already runs VICIdial, you do not replace it. VoiceOI bots join VICIdial as remote agents, so VICIdial keeps your lists, campaigns and reports. You can add many bots at once with bulk provisioning, and each call's outcome comes back to VICIdial as a disposition. The VICIdial AI voice bot page walks through this, and the VICIdial AI integration page covers the setup.
That makes an AI dialer an add-on to your dialer, not a swap. Keep your human reps on the pace your VICIdial campaign gives them, and let bots take the first-contact calls that do not need a person.
On an outbound list, some dials reach a voicemail greeting or another machine. With answering machine detection for outbound calls, the bot recognizes a machine, ends the call and logs it as AM, then moves to the next lead. It never leaves a message after the beep.
Detection uses machine phrase lists, which are editable per organization and can be imported and exported. Check the dispositions and recordings after a run, and adjust the lists to the greetings your leads actually have.
Which bot you dial with decides what happens at the end of the call. AI fronter bots run a short branching script, built in the no-code script builder, then live-transfer qualified leads to your closers. Closer bots carry a longer script with deeper branching. Generative AI lead-generation bots hold a freer conversation, but they do not live-transfer.
A transfer hands the live call to a human closer over SIP, with AI-written notes about the call, on the Good Fronter tiers. Closer routing rules decide who takes each call. See AI live transfer for call centers for the full flow.
Every call ends with a disposition, a recording and a transcript. If you run VICIdial, the disposition is written back to VICIdial. Pro generative (LG) bots can also append one row per call to a Google Sheet; see Google Sheets export for call data. The fronter and closer tiers do not include the Sheets export, and VoiceOI does not import leads from Sheets.
Set from the campaign manager, so the dialer works the hours and the leads you choose.
Choose when a campaign runs, so calls go out during the hours you set.
Bots dial only inside the hours you set for each lead's timezone.
Set how leads that did not connect are tried again, so one miss is not the end of a lead.
Limit a campaign to the places you serve before a single call is placed.
Each call ends with a logged outcome, such as transferred, answering machine or not qualified, written back to VICIdial when you use it.
Concurrency equals the number of bots you run, so capacity and cost are easy to predict.
Three common pricing models. What changes between them is what makes the bill grow.
| Pricing model | You pay for | Your bill grows with |
|---|---|---|
| Per seat | Priced per human user of the dialer. | The number of reps on the floor. |
| Per minute | Priced by talk time. Whether carrier fees are included varies by vendor. | Total talk time across all calls. |
| Per bot (VoiceOI) | Each bot, prepaid monthly: $25 to $155 per bot at list price, with no per-minute AI fee. | How many bots you run, which sets how many calls go out at once. |

Take 10 VICIdial Good Fronter bots. The list price is $35 per bot per month, and the 15% volume discount at 10 bots brings it to $29.75 per bot. That is $297.50 a month for up to 10 simultaneous calls, with no per-minute AI fee.
Carrier charges are separate: with VICIdial you bring your own SIP carrier and pay its rate. Prices by bot type start at $25 per bot per month for fronter bots, $50 for generative AI bots and $100 for closer bots. Discounts reach 60% at 250 bots or more, with a price floor for each tier.

An AI auto dialer and a predictive dialer solve different problems. A predictive, power or parallel dialer keeps a room of human reps busy. An AI dialer replaces the human on the first-contact call. VoiceOI is the second kind only.
Keep your current dialer if your reps make the calls themselves from start to finish. Add VoiceOI if you want bots to make the first call and pass only qualified people to your closers.
Since the FCC's February 2024 ruling, AI-generated voices count as "artificial" voices under the TCPA, so telemarketing calls that use them need prior express written consent. For an AI dialer, that makes your lead list the first compliance question: only load numbers whose owners gave that consent for AI-voice calls, keep the records of when and how they gave it, and remove numbers that opt out. Compliance stays your responsibility.
Once a list is loaded, these controls apply while the dialer runs: timezone calling windows limit when each lead is called, a spoken do-not-call request ends the call, an optional AI-voice disclosure plays at the start, and every call has a recording and a transcript. None of this is legal advice, so check your lead sources with your counsel. See TCPA controls for outbound calling and do-not-call (DNC) controls.
Short answers on concurrency, VICIdial, consent and voicemail.
One call per bot at a time, so your concurrency is the number of bots you run. Your carrier or SIP trunk must also have enough channels to carry those calls at once. Volume discounts apply as you add bots; the worked example on this page shows the numbers.
Yes. Bots appear in VICIdial as remote agents and can be added in bulk. VICIdial keeps your lists, campaigns and reports, and each call outcome is written back as a disposition. If you do not run VICIdial, the built-in dialer runs bot campaigns on its own through any SIP carrier.
AI-generated voices count as artificial voices under the TCPA, so telemarketing calls made with them need prior express written consent from the person called, and the compliance duty stays with you. The TCPA section above covers what that means for the numbers you load. This is not legal advice.
No. When answering-machine detection hears a machine, the call ends and is logged as AM (voicemail). The bot does not leave a message after the beep, and there is no ringless voicemail. The bot moves on to the next lead.
No. Those dialers pace calls so that human reps are never idle, and VoiceOI does not do that. Our bots place and handle the calls themselves. If you pace human reps today, keep VICIdial or your current dialer for that and add bots as remote agents.
Upload a CSV lead list, or keep your lists in VICIdial and let bots work them as remote agents. Pro generative (LG) bots can append each call to a Google Sheet, but VoiceOI cannot import leads from Sheets.
Per bot, prepaid monthly, with no per-minute AI fee. The price depends on bot type and connection, and volume discounts apply as you add bots. The cost table and worked example on this page show the numbers, and every tier is on the pricing page.
