Research and Markets has debuted a new report offering some insights into the growth of the VoIP market. The "US Business VoIP Overview: Optimization Trumps Expansion" report takes In-Stat's recent claim of 79% penetration of VoIP in businesses by 2013, and states that much of the focus in the industry will be on optimizing current systems and upgrading headquarters rather than bringing more VoIP systems to satellite offices.

The 79 percent figure represents company's having VoIP deployed in at least one of their location, meaning the universal use of VoIP throughout these companies is not being implied. The study also found that Hosted IP Centrex is now the leading revenue generator over Broadband IP Telephony for carrier-based business VoIP solutions.
