User Experience

Crossing the Chasm Open Source adoption creates leads and business

Large Reseller Contract Closed Nortel Elite partner makes a strategic choice > “I don’t think they (Avaya) will make it”, Chris Wasp, President, Ronco Communications > Avaya / Nortel Elite Partner > 1, 000 accounts installed base > $80 m annual revenue > Covers Eastern US Exclusive distribution and partner agreement with e. Zuce that includes revenue and resource commitments through 2012 7
