Voice AI agents for inbound and outbound business calls
Agents answer calls around the clock, capture lead details, qualify enquiries and route callers to the right person or department.
Run follow-up calls, collect missing documents or payment reminders at scale, with multi-channel SMS and email alongside the voice call.
Agents book, cancel and reschedule appointments in real time, tying the booking step directly to the call that generated it.
Every conversation produces a transcript, summary and analytics so managers can review what was asked and how it was handled.
Autonomous enterprise AI agents and CRM intelligence powered by Salesforce Data 360 and Atlas.
Deconstructs complex queries into multi-step action plans grounded in Data 360, retaining state across days or weeks to complete multi-touch operational workflows with human escalation guardrails.
Configure custom agents, subagents, natural-language instructions, and deterministic guardrails using existing Salesforce Flows, Prompt Builder templates, Apex code, and MuleSoft APIs.
Coordinate specialized subagents across departments and connect securely to external enterprise tools through verified Model Context Protocol (MCP) servers from AgentExchange partners.
Replace rigid telephone IVR trees with low-latency conversational voice agents alongside unified deployments across web chat, WhatsApp, SMS, mobile apps, and Slack.
