AIOnCalls Developer Platform — connect the AIOnCalls AI Voice Agent and AIonChats AI Chatbot to your CRM, calendar, and workflow tools with native integrations, 2,000+ apps via Zapier, and a REST API with Webhooks.

Developer Platform

Connect AIOnCalls With Your Existing Business Tools

AIOnCalls integrates with your existing CRM, calendar, telephony platform, workflow automation tools, and custom applications to automate customer conversations from the moment a lead is created until the conversation is complete. Whether you're using no-code tools or building custom workflows, AIOnCalls fits into your stack.

Integrations

All Integrations, One Voice Stack

Browse the full voice stack — telephony, language models, speech technology, messaging channels, and the tools and CRMs AIOnCalls keeps in sync.

Telephony

AIOnCalls connects your AI voice agent to the public phone network through enterprise-grade SIP trunking and PSTN calling carriers built for real-time voice AI — Twilio, Telnyx, and Exotel. Bring your own number and keep it: AIOnCalls doesn't sell or provision phone numbers, so number ownership and portability always stay with you. Every plan, from inbound call answering to outbound AI calling campaigns, routes through a carrier you already control.

Speech-to-Text

Accurate automatic speech recognition (ASR) is what lets an AI voice agent understand a caller in real time. AIOnCalls auto-selects the best-fit speech-to-text provider per language and accent, so live, full-duplex phone calls transcribe correctly even through interruptions, background noise, and barge-in. Supported speech-to-text engines: Deepgram, Google Speech-to-Text, and Sarvam AI for Indic-language calling — routed automatically, with nothing to configure manually.

Text-to-Speech

A natural, human-like speaking voice is what makes an AI voice agent believable on a phone call. AIOnCalls routes text-to-speech (TTS) generation to the right voice engine underneath, so you can preview and pick a voice and persona for each agent before going live — no code required. Supported text-to-speech and AI voice-cloning providers: ElevenLabs, Cartesia, Deepgram Aura, Murf, Sarvam AI, and Inworld.

Messaging

AIonChats deploys the same AI chatbot agent across every conversational channel your customers already use — WhatsApp Business, Facebook Messenger, Instagram DM, and your own website chat widget — from one shared knowledge base and one dashboard, so answers stay consistent across every channel. Omnichannel AI chatbot integration means a lead can start on WhatsApp and finish on your website without losing context.

Tools & CRMs

Every AIOnCalls call and AIonChats conversation can automatically create contacts, update lead stages, book calendar time, send follow-up email and SMS, and sync customer data back to the CRM and calendar your sales and support teams already run on. Native CRM integration is built for Salesforce, HubSpot, and Zoho CRM, with Google Calendar for real-time appointment booking, Google Sheets for auto-exported lead data, SendGrid, Gmail, and Mailchimp for follow-up email, Twilio/Telnyx for follow-up SMS, and Zapier, Make, and n8n workflow automation connecting AIOnCalls to Pipedrive, Monday CRM, Microsoft Dynamics 365, Freshsales, Pabbly, and 2,000+ more business tools.
