The Majority of companies, especially medium to larger sized companies, are gradually upgrading their PBXs to hybrid IP/TDM solutions. This allows corporations to migrate to IP telephony at their own pace, rather than completely overhauling their telephony network. It is estimated that by 2009, 74% of all corporate telephony lines will be IP lines.
Worldwide revenue for hybrid and pure IP PBXs is expected to grow from approximately $1.5 billion in 2005, to $9.9 billion in 2009.
