Aircall

Cloud-based customer communications platform that unifies voice, messaging, and AI for sales and support teams. Replaces traditional business phone systems with a cloud-native alternative: call routing, IVR, power dialing, voicemail, and team collaboration, plus AI voice agents and WhatsApp in one interface.

Trusted by over 22,000 companies and recognized as a G2 Call Contact Center Leader. Differentiates with a developer-first API: REST endpoints for calls, contacts, numbers, and conversation intelligence, webhooks for event-driven workflows, and an Everywhere SDK for embedding the phone in any web application. Integrates with 100+ tools including Salesforce, HubSpot, Zendesk, and Intercom.

Key features:

• REST API with OAuth and webhooks for call activity, recordings, and CRM sync
• AI Voice Agent for autonomous inbound qualification and AI Assist for real-time conversation intelligence
• WhatsApp messaging alongside voice and SMS in a unified interface
• Insight Cards to display customer data from external systems inside the phone UI
• App Marketplace for distributing integrations to thousands of companies

Developers embed calling into CRMs and help desks via the Everywhere SDK, sync call logs and recordings to data warehouses, and automate post-call workflows with webhooks. Sales teams use power dialing and AI-assisted prep, while support teams route calls by skill set and handle WhatsApp alongside phone in one place.
