​Introduction to callmanager-4-1-3-disk2.iso​

This ISO image contains the secondary installation components for Cisco Unified Communications Manager (CallManager) 4.1(3), released on July 25, 2005, as part of Cisco’s enterprise VoIP solution. Designed for cluster expansion and system recovery, this disk complements the primary installation media to deliver SQL Server 2000 integration, DC Directory services, and critical security patches for Cisco Media Convergence Servers (MCS-7800 series).

Targeted at enterprises managing 50-30,000 IP phones, the software enables centralized control of Cisco IP Phone 7900 series devices, SIP/H.323 gateways, and CTI applications. It supports clustered deployments with triple-call processing redundancy for mission-critical environments.


​Key Features and Improvements​

  1. ​Cluster Scalability Enhancements​

    • Supports up to 8 active CallManager nodes per cluster
    • 15% faster database synchronization via SQL Server 2000 SP3a optimizations
    • Extended RSVP-based QoS management for WAN links
  2. ​Security Updates​

    • TLS 1.0 encryption for intra-cluster communication
    • Private Password Phrase enforcement during installation
    • Fixed 3 critical vulnerabilities (CSCsb39207, CSCsb41732, CSCsb40165)
  3. ​Protocol Support​

    • MGCP 1.0 compliance for analog gateway integration
    • Early SIP trunking support (RFC 3261 partial implementation)
    • H.323 v4 compatibility for legacy PBX interconnects
