To further simplify business operations and take advantage of cost savings and advanced features associated with IP telephony, IBM clients will be able to run 3Com’s IP Telephony Suite on the System i platform

Sydney, Australia– 3 April, 2006 – IBM and 3Com Corporation, a leading provider of secure, converged voice and data networking solutions, have announced plans to offer the 3Com VCX™ suite of IP telephony solutions on IBM’s “all-in-one” System i business computing solution.

Through this agreement, IBM and 3Com will enable small-to-mid-sized (SMB) clients to integrate IP telephony capabilities with the System i, which comes pre-integrated with hardware, database software, storage and security. To simplify the convergence, IBM and 3Com intend to deliver the first IP telephony suite that can run in a single Linux on POWER partition on the System i. This means clients will be able to run business and telephony applications simultaneously, managed by the System i’s familiar system management tools.

The System i IP Telephony Suite is designed to help clients take advantage of IP telephony features and cost savings versus traditional telephony systems while delivering the same level of reliability that they expect from their business computing on System i.

“The availability of the 3Com solutions on the System i platform will give our broad base of clients a powerful option to run a complete IP telephony solution without adding new boxes to their environment,” said Mark Shearer, general manager, IBM System i. “This is a milestone in further simplifying the avalanche of data that small and medium-sized clients face and enabling innovation in their businesses. We think this offering will provide our community with yet another reason to be passionate about the System i.”

Focusing on the mid-market of 100 to 2,000 users, 3Com delivers a completely native, standards-based IP telephony and application solution using SIP (Session Initiation Protocol). By using SIP and other open standards, 3Com IP telephony offerings will be more easily integrated with other applications on the System i to extend their functionality with telephony features and applications, including unified messaging, large scale audio conferencing, video conferencing, presence, contact centres and enterprise mobility that reduce cost, increase productivity and enhance customer interaction. 3Com’s VCX solution delivers robust dependability and scalability that carries billions of minutes of IP Telephony traffic with carrier-class availability

IBM chose 3Com as its IP telephony partner for System i based on the two companies’ common values of integration, ease-of-use, security, and support for open standards.

“By collaborating with IBM, we have an enormous opportunity to enable System i clients and enterprises worldwide to take advantage of the benefits that IP telephony has to offer through our VCX suite and applications,” said R. Scott Murray, president and chief executive officer, 3Com. “Integrating VCX with the System i5 creates a converged environment that reduces costs while giving enterprises a competitive edge. IBM’s selection of 3Com and the VCX platform is a proof point for the product’s flexibility and reliability. It is also tremendous validation for our open standards-based approach versus proprietary systems.”

IBM anticipates that its community of System i business partners and Independent Software Vendors (ISV) will exploit this IP telephony functionality to deliver new innovations in collaboration and key business processing applications such as customer relationship management applications that run on the System i platform.

“IP telephony is a solution area that is becoming more and more important to our customers," said Andy Gorelik, COO, Strategic Computer Solutions, Inc., an IBM Premier Business Partner. "We think offering 3Com's IP telephony solution on System offers a new level of IP telephony simplicity, and will drive new innovation and demand for the System i platform.”

Availability The first software products for integration onto System i are expected to be available by third quarter 2006.
