3Com® VCX™ IP Telephony Module—the Leading SIP-PBX

The 3Com® VCX™ IP Telephony module is one of a series of applications in the 3Com Convergence Applications Suite designed to help companies eliminate the boundaries of time and distance. The software suite is built around a simple idea—telephony is an enterprise application, critical to delivering an advanced portfolio of real-time telephony, presence, messaging, and conferencing services to users anywhere in the world, within a common framework of call control, authentication, privacy, location, and presence management services.

The VCX IP Telephony module features the high availability functionality implemented in telco environments and the enduser features expected from PBX systems. Users authenticate themselves to an IP phone for accessing personal settings such as soft buttons, speed dials, and call logs. The IP phones are registered to VCX call controllers that are organized in a hierarchy to minimize costly interruptions in business operations. In the unlikely event of a call controller failure, user settings can be available immediately and registered on a backup controller using the 3Com Voice Boundary Routing service. In this way 3Com can deliver the high availability of redundancy without the anticipated expense.

The VCX IP telephony module enables the following enterprise advantages:

• High-availability network designs with intelligent mirroring and support for automatic backup
• Proven compatibility with SIP-compliant devices
• Smooth upgrading of existing digital or IP telephony systems-gateways can surround PBX, and 3Com IP phones can be reused in NBX® to VCX migrations
• Exceptional scalability to ease the expense of growth—system management, including scripting of configuration updates is supported by the 3Com Enterprise Management Suite

• Easy access to advanced telephony services with Presence module integration to provide intelligent user availability tracking
• Integration with SIP-based applications such as IP Messaging and IP Conferencing
• Straightforward support for teleworking

• Support for remote service agents, enabling "happier" agents with fewer distractions when working from their home environment
• A wide range of business-quality, high-fidelity worktop options, including business phones and attendant console with practical and versatile capabilities such as easy access to a company's internal user directory, speed dials, and even personal call log
