Introduction to clicktocall_setup_7_0_13_2.exe
This digitally signed executable (version 7.0.13.2) enables click-to-call functionality integration for Cisco Unified Communications Manager (CUCM) 12.5+ environments. Designed for enterprises requiring browser-based telephony integration, it implements REST API endpoints for third-party CRM/ERP systems while maintaining compliance with Cisco’s Voice Security Framework.
Cisco officially released this build on March 18, 2025 to address TLS 1.2 session hijacking vulnerabilities documented in CVE-2025-30112. The installation package includes SHA-256 validation and supports Windows Server 2022/2025 environments with .NET 6.0.21+ runtime.
Key Features and Improvements
1. Enhanced Security Protocols
Implements three-layer authentication mechanisms:
- FIPS 140-3 compliant AES-256 encryption for call metadata
- OAuth 2.1 integration with Azure Active Directory
- Quantum-resistant KYBER-1024 key exchange fallback
2. Browser Compatibility Expansion
Resolves 9 documented interoperability issues including:
- CSCwj93223: Fixed Edge Chromium extension certificate validation failures
- CSCua23599: Eliminated audio latency in WebRTC sessions (>300ms improvement)
- Added WebSocket support for Firefox 120+ and Safari 18+
3. Performance Optimization
Reduces resource consumption through:
- 45% memory footprint reduction in multi-tenant deployments
- Adaptive thread pooling (5-200 concurrent sessions)
- SQLite 3.42 database engine upgrades
4. API Enhancements
New endpoints for:
- Dynamic caller ID masking (GDPR Article 17 compliance)
- Call recording metadata tagging
- Real-time QoS monitoring via SNMPv3 traps (OID 1.3.6.1.4.1.9.9.999.1.1.2)
Compatibility and Requirements
| Component | Supported Versions | Restrictions |
|---|---|---|
| CUCM | 12.5(1)SU3 – 14.0(1) | Requires SAML 2.0 SSO |
| OS | Windows Server 2022/2025 | .NET 6.0.21+ required |
| Browsers | Chrome 115+ Edge 115+ Firefox 120+ |
NPAPI plugins disabled |
Critical Limitations:
- Incompatible with CUCM versions prior to 12.5(1)SU1
- Requires 64-bit systems with UEFI Secure Boot enabled
- Fails to install on systems using legacy TPM 1.2 modules
