Dialpad

Dialpad is a cloud business communications platform combining VoIP calling, SMS, video meetings, and a contact center product into one workspace, with real-time AI transcription and coaching layered across calls and meetings. It positions itself around agentic AI features that can autonomously handle tasks like booking appointments or processing simple requests during support conversations. The platform is split into several products: Dialpad Connect for unified business communications, Dialpad Support for contact centers, and Dialpad Sell for outbound sales teams, each sharing the same AI transcription and analytics engine and integrating with tools like Salesforce, Zendesk, and Microsoft Teams.

Aircall

Aircall is a cloud phone and customer communications platform built for sales and support teams. It provides VoIP calling, SMS, and shared team inboxes alongside AI features such as live call coaching, automatic transcription, and autonomous AI voice agents that can handle routine customer interactions end to end.

Sup AI

Sup AI is an AI employee for your business. Each AI employee gets its own phone number, its own computer, and a persistent memory. It is hired in about a minute, starts by calling you to learn the business, then handles calls, callbacks, notes, follow-ups, email, Slack, and other software just like a human employee.

RingCentral

RingCentral is a cloud unified-communications platform (branded RingEX) used by over 600,000 businesses for business phone calls, SMS, team messaging, and video meetings in one subscription. It layers AI features on top of core telephony, including an AI Receptionist for automated call handling, an AI Virtual Assistant for meeting notes and translation, and conversation analytics/coaching. Beyond RingEX, RingCentral offers RingCX, a cloud contact center product for omnichannel customer support and outbound dialing. The platform runs on a global network with 99.999% claimed availability across 100+ countries and holds HIPAA, GDPR, SOC 2, and PCI DSS compliance, with 330+ third-party integrations including CRM tools like Salesforce and HubSpot.

Quo

Quo, rebranded from OpenPhone in September 2025, is a VoIP-based business phone system that gives teams shared numbers, calling, and SMS/MMS messaging in one collaborative inbox. Multiple teammates can see and respond to the same business number's calls and texts, with routing rules to direct incoming contacts to the right person. Quo layers an AI agent called Sona on top of the phone system to answer calls automatically, transcribe conversations, and summarize them, along with call recording and analytics. It is used mainly by startups and small businesses that need a professional, multi-line phone presence without deploying a traditional PBX, and it integrates with common CRMs like HubSpot and Salesforce on its higher tiers.

SuperCalls

SuperCalls is an AI-driven bulk call platform that helps individuals and teams reach hundreds of contacts in minutes. Instead of manually dialing one number at a time, users upload a CSV list of phone numbers, write a ChatGPT prompt that guides the conversation, and the voice bot places calls simultaneously. Each conversation is designed to feel natural and human, and the system extracts structured data from every call for easier follow-up. SuperCalls is built around a simple workflow: import contacts, define the prompt, and start a batch call. The AI handles the conversation, then produces call summaries, transcriptions, and automatic tags. Completed calls appear on a Kanban board, where cards move to relevant columns based on the outcome so users can prioritize next steps. The interface is mobile-friendly, allowing outreach management from a phone while on the go. The product is positioned as a lifetime-deal tool with a one-time payment rather than monthly fees. It integrates with Bland AI as the voice-calling engine and OpenAI for call processing, so users bring their own API keys and pay those providers directly for usage. SuperCalls is suitable for sales teams, recruiters, and anyone coordinating group events, reminders, or personal outreach.
