Aspect Communications Announces Results of Open Source IP-PBX Testing of Aspect Uniphi Suite

Rapid completion of testing demonstrates significance of open standards for next- generation contact center applications

SAN JOSE, CA (February 22, 2005) — Aspect Communications Corporation (Nasdaq: ASPT), a leading provider of enterprise customer contact solutions, announced today the successful completion of tests running Aspect® Uniphi Suite, an integrated set of award-winning next-generation contact center applications, on Asterisk®, an open source IP-PBX. Uniphi Suite delivers a wide range of contact center functionality on open standards-based software and offers a single point of control for viewing and managing contact center operations. Integration and functionality testing was completed in less than one week, demonstrating the ease of integration possible when existing and emerging technologies are built on open standards.

According to Gartner Research Director Nikos Drakos, "This test demonstrates that products supporting a common set of technology standards provide for more rapid integration and simpler administration."

Tests consisted of the integration of Uniphi Suite with the Asterisk IP-PBX, as well as a demonstration of call handling functionality including queuing, collecting, routing, prompting and transferring, and advanced speech recognition-driven self-service. Uniphi Suite's use of SIP (session initiation protocol) enabled it to communicate almost immediately with the Asterisk system. Uniphi Suite also supports other technology standards such as Web services, SOAP, VXML, HTTP and SNMP.

"As an industry leader, Aspect must respond to its customers' needs for greater flexibility in solution design and configuration," said Brian Gentile, senior vice president and chief marketing officer of Aspect. "Our demonstration represents Aspect's continued commitment to evolve the contact center for customers by delivering intelligent applications that are cost-effective, practical and able to address widely varying business needs."

"Completion of the Aspect Uniphi Suite testing on Asterisk is an important milestone for establishing the reliability and flexibility of the project," said Mark Spencer, president of Digium and the author of Asterisk. "This test should reinforce the value of Asterisk, open source and open standards in building next-generation infrastructure and creating innovative new telephony applications."

Aspect will demonstrate Uniphi Suite on Asterisk in Digium's Asterisk Marketplace at the VON show in San Jose, CA, March 7-10.
