I’m out at the Broadsoft Connections conference in Phoenix, AZ and I’m trying to stay as productive as possible while meeting with senior-level executives at a number of Broadsoft’s partner companies.   The event kicked off with an introductory keynote by Broadsoft president and CEO Michael Tessler. The theme of this year’s conference, Scaling New Heights, was brought to life by a series of BMX bikers performing acrobatic feats — twists and turns and flips and jumps — on an indoor series of ramps set up for the event. Very exciting, and very fitting given Tessler’s subsequent comments.   Tessler spoke about the growth of the market, as well as the growth of the opportunity. He broke the market down for the standing room only audience, and settled on three key areas which will bear watching over the next few years.   He cited industry stats that show the potential size of the market as follows:   Hosted Voice/Hosted Applications: Infotek said that by 2010 marketplace for hosted voice and services would be $37 Billion, and the hosted voice part of that would be approximately $10B.   Business Trunking: Frost & Sullivan stated that connecting customer premise-based equipment to the network was an opportunity approaching $11B in 2006.   Residential Opportunity: Back in February, Ovum announced its view that the 2010 worldwide voice/residential opportunity would be equal to about $40 billion.   He summed up by telling the audience that the market is growing, and growing quickly.
