Eight-three percent of the North American, European, Asia Pacific, and Central and Latin American service providers in the study said that the need to generate new revenue is the primary reason they are migrating circuit-switched voice networks to packet networks. In particular, they hope the launch of new applications and services via VoIP will bring in additional revenue.
The study also found that:
* The top drivers for deploying VoIP are new applications and services, capex savings, and opex savings.
* The service providers' main barrier to using VoIP is potential problems with equipment interoperability
