Allo

Business phone system with AI agents.

Visit Allo

Allo is a business phone system for teams under 250 people, combining calling, SMS, voicemail, call recording with AI summaries, and AI agents that answer calls and update CRMs. It solves problems like dropped calls, spam flags, cumbersome administration, and manual CRM entry by providing reliable call quality, an easy-to-use app, and proactive AI that handles follow-ups and record-keeping.

Core capabilities include call recording with transcription and AI summaries, call tags, post-call actions, voicemail-to-text, call routing with cascade and simultaneous ring, a power dialer, click-to-call, spam blocking, and two-way SMS with automatic missed-call texts. The AI Receptionist answers, qualifies, and books appointments, while an AI IVR routes callers. Integrations are native and cover CRMs like HubSpot, Salesforce, Pipedrive, and Attio, plus scheduling tools like Calendly and Google Calendar, with Zapier and Make for broader automation. A public API, webhooks, and an MCP server let teams connect Allo to AI clients such as Claude and Cursor. It runs on iOS, Android, macOS, Windows, and web.

Allo is aimed at lean teams and smaller organizations rather than enterprises. It is packaged as seat-based plans (Solo, Business, and Ultra), with a 7-day free trial and a 30-day money-back period. The AI receptionist and power dialer are optional add-ons, and number porting is included at no cost.
