This study looks at a subsegment of managed network services — managed IP PBX services — in Western Europe. In line with the booming managed network services market, the managed IP PBX services market is expected to grow rapidly over the next five years.

"The market for managed IP PBX services will be driven by the rapidly evolving platforms, applications, and new versions that the IP PBX vendors introduce to the market. The increased complexity of the platforms, applications, and new versions will exceed the in-house expertise of most businesses, resulting in increasing demand for managed IP PBX services," said Roosmarijn Cornelissen, research analyst, European Network Life-cycle Services.
