Adversus is a cloud-based predictive and progressive dialer designed for outbound call centres and sales teams. It combines automated dialling modes with a built-in CRM, workflow automation, and real-time performance dashboards — giving managers and agents a single platform for high-volume outbound calling campaigns.
Product Overview
Adversus supports predictive, progressive, and manual dialling modes, allowing teams to optimise for connection rate versus compliance requirements depending on their market. Its built-in mini-CRM tracks contact history, call outcomes, and follow-up tasks without requiring a separate CRM subscription for smaller operations. The platform's workflow automation routes leads, assigns agents, and triggers follow-up actions based on call outcomes — reducing post-call admin. Real-time dashboards show live call metrics, agent performance, and campaign progress, enabling supervisors to intervene or coach without leaving the platform. Adversus is particularly popular in Scandinavian markets and with European outbound teams who need GDPR-compliant dialling with consent tracking built in.
Key Features
- Predictive Dialling: Auto-dials multiple numbers simultaneously and connects agents only when a live answer is detected — maximises talk time.
- Progressive & Manual Modes: Switch between dialling modes per campaign — progressive for compliance-sensitive lists, manual for complex enterprise outreach.
- Built-in CRM: Contact management, call history, and outcome tracking without a separate CRM — suitable for teams without an existing system.
- Real-Time Dashboards: Live visibility into agent activity, connection rates, and campaign performance for supervisors and managers.
- GDPR Compliance Tools: Consent tracking, do-not-call list management, and data retention controls built into the platform.
