market analysis: VoIP vs traditional telephones

["Enyeart, Mike" <>]

I’m trying to find information on the USA and/or international sales of new telephone “lines” comparing PBX/Centrex (traditional telephone technology) line sales vs. VoIP line sales, broken down by year, so I can better understand the VoIP market. 

 

Most of my web searches have led to sites that charge thousands of dollars for that information.  Please send any URLs that point to this information directly to .  I will compile the URLs and post them here in about a week or so.  Thanks.
