## Positioning

EchoCall combines two products other vendors typically split into separate stacks:

1. **AI Voice Agents** — autonomous phone agents for inbound and outbound calls.
2. **AI Chat Agents** — autonomous chat agents for web, WhatsApp, Telegram, SMS and WordPress.

Both share one knowledge base, one analytics layer, one billing dashboard (EchoHub), one set of integrations and one white-label engine. Most competitors do voice or chat, US-hosted or EU-hosted, SaaS or self-hosted. EchoCall covers all axes from a single platform.
