The growth of the NGEV services market will be primarily driven by three factors.
This will lead to a technology shift from Time Division Multiplexing (TDM) Centrex to IP-based NGEV services.
By 2011, we expect emerging IP-based NGEV services, including IP Centrex and managed IP PBX, to account for nearly 87 percent of the total enterprise voice market in Asia Pacific, up from a mere 15.
Although limited cross-country coverage represents a major barrier to the growth of advanced telephony services, China's large size, coupled with the popularity of VoIP services, is likely to favor the adoption of managed NGEV services.
The emerging competitive marketplace for NGEV services includes a number of ISPs, SIs, solution providers, and platform vendors.
