Manual Calling is Broken
Sales reps spend 80% of their time on manual dialing, hold music, and voicemails. Hiring more agents doesn't scale — costs spiral with no proportional gain.
Inbound Goes Unanswered
Prospects calling after hours, during peak loads, or on weekends hit voicemail or hold queues. Every missed call is a lost opportunity.
Campaigns Are Disconnected
Running SMS, WhatsApp, email, and voice as separate silos means fragmented data, duplicated effort, and zero unified reporting.
One Platform.

Common Questions
Does Voice Nimble use real human voices?
Your AI agent uses high-quality TTS (Text-to-Speech) models that sound natural and conversational. You can choose from multiple voice models and customize the tone.
How does the RAG Knowledge Base work?
You upload your documents (PDFs, manuals, FAQs). Our system indexes them into a vector knowledge base. When a caller asks a question, the AI retrieves the most relevant answer from your documents — not from generic training data.
Can I use my existing phone numbers?
Yes. Voice Nimble supports number setup with your existing telephony provider, or you can provision numbers through the platform.
Is there an API?
Absolutely. Voice Nimble has a full REST API for calls, contacts, orders, audio, and messaging. See the API docs for full reference.
What messaging channels does it support?
Voice calls (inbound + outbound), WhatsApp Business API, SMS (multiple providers), and email (Gmail SMTP). All from one unified inbox.
Can I schedule broadcasts across different timezones?
Yes. The broadcast scheduler supports all global timezones. Schedule once, and Voice Nimble delivers at the right local time.
Is there a free trial?
Yes — a 14-day free trial is available on all plans. No credit card required.
How do I handle inbound calls after hours?
Configure an AI inbound call agent that's always on. It handles calls 24/7, answers questions from your knowledge base, and can route to an on-call number if needed.
