Introducing Virtual Agents

CompletePBX 5.3.0 introduces Virtual Agents, a powerful AI-driven communication tool designed to automate interactions and enhance the caller experience. This release features two primary agent types: Receptionist and Informative.

Watch the video here.

Virtual Agent: Receptionist

The Receptionist type is designed to handle inbound calls, identify the caller’s intent, and route them to the most appropriate destination.

      • Intelligent Call Routing: Call routing is dynamically performed based on the names, skills, departments, and free-text information defined for extensions, queues, ring groups, and other Virtual Agents.
      • Customizable Dynamic Messaging: Custom greeting and transfer messages with support for real-time placeholders like ${agent_name}, ${department}, and ${job_title}.
      • Customizable AI Persona: Configure the agent’s voice gender and language to match your brand identity.
      • Advanced Instructions: Provide the AI with specific operational guidelines and “Advanced Settings” for tailored behavior.
      • Recording & Transcription: Optional toggle to record interactions and transcribe conversations for quality assurance.
      • Safety Fallback: Define a specific “Failure Destination” to ensure callers are always connected to a human if the AI cannot complete a request.

      Virtual Agent: Informative

      The Informative agent type is designed to serve as a 24/7 AI-powered knowledge assistant, providing callers with specific information based on your uploaded documentation.

        • Custom Knowledge Base: Upload your own support documents, manuals, or FAQs (supports DOCX, PDF, TXT, and MD files) to train the agent on your specific business data.
        • Comprehensive Information Delivery: The agent uses the provided “Knowledge Base” and “Instructions” to answer caller inquiries accurately without needing to transfer.
        • Session Management: Set a Max Call Duration to manage system resources and ensure efficient interactions.
        • Structured Exit Paths: Define a specific Exit Destination for when a caller successfully finishes their inquiry, and a Failure Destination for unresolved issues.
        • Voice & Persona Control: Fully customizable language and voice gender settings to maintain a consistent brand voice.
        • Quality & Monitoring: Built-in Recording & Transcription toggle for reviewing AI-caller interactions and improving the knowledge base.

        General

        • New Feature: Added support for DTMF pattern matching (e.g., _XXXX) in IVR entries, allowing callers to input variable digits that can be passed to external applications.
            • New Feature: Added an “End of Month” option to CDR settings to support automated external data dumps for billing purposes.
                • New Feature: Added an “Update/Replace” option for system recordings, allowing admins to swap existing audio files globally across all modules (IVR, Queues, Announcements) without manual reconfiguration.
                  • Added an eye-toggle icon to the main login password field to allow users to mask or unmask their password for easier entry.
                  • Removed the “Custom Destination” option from Inbound Routes.
                  • Removed “Custom Destination” from the CID Based Routing module.

                  Security

                  • We have updated the security baseline for Debian 11/12 systems to meet high-compliance standards and protect against modern vulnerabilities.
                    • Disabled insecure legacy protocols (SSLv2, SSLv3, TLS 1.0, and TLS 1.1).
                    • Hidden OS and Apache version details from HTTP headers to prevent reconnaissance.
                  • Improved system error handling to display only generic messages to users; detailed technical stack traces and exception logs are now restricted to internal diagnostic logs.
                  • Hardened the Status Report module by implementing strict input validation and output encoding for device descriptions, preventing potential script execution in the browser.
                  • Upgraded database query processing across all modules to use parameterized queries, providing robust protection against SQL injection.

                  Auto Provisioning

                  • Added support for handset.x.ipui (International Portable User Identity) for Yealink W70B to enable unique DECT handset registration.
                  • Improvement: Fixed the search bar to the top of the screen in the device list to ensure it remains visible while drilling down into device details.

                    Cloudphone

                    • Whitelisted new Acrobits cluster IP addresses in Fail2Ban to support their capacity expansion.

                    Bug Fixes

                    • Statexplorer: Fixed an issue with the IVR Statistics Report not showing any data.
                    • Resolved an issue where view-only users could modify settings in the Extension Status module.
