Natural Intonation & Pacing

Context-Aware Responses

Not a script reader — the AI understands context, remembers earlier parts of the conversation, and responds to what the prospect actually said, not what it expected them to say.

20+ Languages, Native Fluency

Conduct calls in English, Spanish, French, German, Portuguese, Japanese, Mandarin, and more — each with native-sounding voice models, not translated English.

Objection Handling Mastery

Trained on thousands of real sales conversations. The AI handles pushback naturally — acknowledging concerns, providing social proof, and pivoting without being pushy.

Appointment Booking

From Cold Call to Calendar Invite in One Conversation

The AI handles the entire booking flow during the call, checking availability, proposing slots, and sending confirmations automatically.

During the conversation, the AI identifies buying signals, confirms the prospect fits your ICP, and naturally transitions toward scheduling a meeting.

02

Checks Calendar in Real Time

The AI queries your Google Calendar, Outlook, or Calendly for available slots and proposes times that work. If the first slot doesn't work, it offers alternatives instantly.

03

Confirms & Sends Invite

Once a time is agreed, the AI confirms the booking, sends a calendar invitation to the prospect's email, and logs the meeting in your CRM — all before the call ends.

FAQ

Frequently Asked Questions About AI Cold Calling

Everything you need to know about using AI voice agents for outbound cold calling, inbound handling, and appointment setting.

Can AI make sales calls?
Yes. Modern AI cold calling software like Sellinger can conduct full two-way phone conversations with prospects: qualifying leads, handling objections, answering questions, and booking meetings autonomously. With sub-200ms response latency, AI sales callers are virtually indistinguishable from human SDRs. In blind tests, 85%+ of prospects can't tell they're speaking with AI.
How does AI cold calling work?
AI cold calling uses a three-step pipeline: speech-to-text (STT) converts the prospect's voice to text in real-time, a large language model (LLM) generates an intelligent response using your product context and call strategy, and text-to-speech (TTS) delivers the response in a natural voice. Sellinger's AI cold calling software completes this entire loop in under 200ms, enabling fluid, natural conversations.
What is a voice AI agent?
A voice AI agent is autonomous AI software that conducts phone conversations, making outbound cold calls and handling inbound calls without human intervention. Unlike traditional autodialers that play pre-recorded messages, a voice AI agent listens, understands context, responds naturally, handles objections, and books meetings in real-time. Sellinger's AI sales caller supports 20+ languages with native-sounding voice models.
How realistic does the AI voice sound?
Our voice AI uses state-of-the-art neural speech synthesis with natural intonation, pace variation, and conversational fillers like 'um' and 'right.' In blind tests, over 85% of prospects cannot distinguish our AI from a human caller. We offer multiple voice personas across genders, ages, and accents.
What happens if the prospect asks something unexpected?
The AI handles a wide range of objections and questions using your product context, training data, and knowledge base. For truly unexpected queries, it gracefully transitions, either offering to send more info via email or booking a meeting with a human representative. It never freezes or gives nonsensical answers.
Is AI cold calling legal?
AI calling is legal in most jurisdictions when following regulations like TCPA (US), GDPR (EU), and local telemarketing rules. Sellinger includes built-in compliance features: DNC list checking, calling hour restrictions, consent management, and automated disclosure that the call is AI-assisted where required by law.
How is pricing structured for the AI Caller?
AI Caller uses usage-based pricing: you pay per minute of call time. This means you only pay for actual conversations, not for unanswered calls, busy signals, or voicemail detection. Volume discounts are available for teams making 10,000+ minutes per month.
Can the AI leave voicemails?
Yes. When a call goes to voicemail, the AI can leave a personalized voicemail message tailored to the prospect's profile and your campaign goals. Voicemail drops are charged at a reduced per-drop rate, not per minute, making them extremely cost-effective.
What languages does the AI Caller support?
The AI Caller supports over 20 languages including English, Spanish, French, German, Portuguese, Italian, Dutch, Japanese, Korean, Mandarin, Arabic, Hindi, and more. Each language uses native-sounding voice models, not translated English with an accent.
How does real-time appointment setting work?
During the call, the AI checks your calendar availability in real time via Google Calendar, Outlook, or Calendly integration. It proposes available slots, handles scheduling conflicts, confirms the time, and automatically sends a calendar invite to the prospect, all within the same conversation.
Can I listen to call recordings and review transcripts?
Every call is recorded (where legally permitted) with full AI-generated transcripts available within seconds of the call ending. You can search, filter, and annotate transcripts, flag calls for review, and export data for team coaching or CRM logging.
How does the AI handle inbound calls?
For inbound calls, the AI answers instantly with zero wait time, qualifies the caller using your ICP criteria, answers product questions from your knowledge base, and either books a meeting, transfers to a live agent, or captures lead information, all based on rules you configure.
What's the difference between AI Caller and a traditional autodialer?
Traditional autodialers play pre-recorded messages. Sellinger's AI Caller conducts real, two-way conversations: it listens, understands context, handles objections, answers questions, and adapts in real time. It's the difference between a robocall and having a skilled SDR on the phone.
