This may be kind of silly, but I really liked this quote that Rich Tehrani blogged recently, which he attributed to Dr. Christian Stredicke, from the second day of the Voice Peering Forum Spring 2006 in Miami:

This is the year where a purchasing manager has to explain why they are buying TDM equipment. Prior to this time you had to explain why you were purchasing VoIP equipment.

I suspect it’s true, as TDM-based equipment and solutions do seem to be rapidly falling by the wayside. Yet another indication that this is truly the year that VoIP breaks through the remaining barriers to become a widely-used and mainstream technology.
