What it is
Sonalyx provides autonomous voice agents for customer service, sales, and operations, handling both inbound and outbound calls. Agents process speech, intent, entities, and sentiment, apply rules, access business systems, take actions, and confirm outcomes by SMS, WhatsApp, or email. Conversation features include turn-taking, interruption handling, context awareness, background-noise handling, and escalation to a person. The site says agents support more than 50 languages and can switch languages during a call. Listed applications include surveys, customer care, technical support, sales, bookings, and collections. Integrations include Salesforce, HubSpot, Dynamics 365, SAP, Zendesk, Intercom, Zoho, Shopify, Twilio, WhatsApp, Slack, Microsoft Teams, Google Calendar, Calendly, Zapier, and its API. Access is available through web, API, and self-hosted deployment. Plans use prepaid conversation time: the Free plan includes 20 minutes, while Starter costs €200, paid once and Professional costs €1,200, paid once. Enterprise pricing is custom and not listed.
