AltiGen Communications to Present at TMC's Internet Telephony Conference and Expo

Touted as the “largest VoIP marketplace in the world,” Internet Telephony Conference and Expo is expected to attract 4,000 VoIP trackers, including service providers, government, developers and reseller representatives. The Miami event will feature new VoIP/IP telephony products on display, as well as keynote speakers from leading service providers and manufacturers.

During the show, Mr. Puchbauer will speak in two separate sessions:
• Mr. Puchbauer will present “Turbocharge Your Call Center with Integrated CRM,” on Wednesday, February 23, from 10:15 - 11:00 a.m., in Orchid A & B. The discussion covers how the combination of Customer Relationship Management (CRM) and advanced phone system (IP contact center) functionality provides businesses with real power and how integrating a business’ contact center telephone system with a CRM application yields boosted productivity and customer service levels.
• In the “Future of IP Telephony” keynote panel discussion set for Wednesday, February 23, 5:15 – 6:15 p.m. in the Flagler/Monroe room, Mr. Puchbauer will share his thoughts and predictions about the expanding VoIP market, which Gartner Dataquest estimates will become a $4.2 billion market in 2007 as a result of increased enterprise spending on IP phone systems in North America.
• AltiGen will be participating in the solutions exposition booth #403 where there will be a complete VoIP telephone system and call center integrated with Microsoft Customer Relations Management System set up for demonstration.
