4.1 million VoIP Subscriber Feature Server licenses sold in 2Q07


In 2Q07, vendors shipped a total of about 4.1 million VoIP Subscriber Feature Server (SFS) licenses for deployment in service provider networks, generating $76.9 million in revenue. As in previous quarters, Europe is leading in the VoIP SFS deployment owing to a strong residential VoBB market. However, North America was not that far behind during the quarter.

Cisco leads the VoIP SFS lines market on a worldwide basis with a market share of 15.8 percent. That lead is followed by UTStarcom at number 2 and Comverse at number 3 worldwide.

Within the 4.1m VoIP SFS licenses sold during 2Q07, business centrex lines account for over 0.4 million. The remaining 3.7 million were mainly deployed for residential VoBB and Class 5 switch replacement.

Please note that iLocus does not track IP upgrades to TDM ports. We only track pure VoIP deployments which in the context of Class 5 NGN includes VoIP hosted telephony implementations (such as hosted PBX and VoBB), new Greenfield VoIP deployments, complete replacement of legacy switches with VoIP, and extension of existing legacy networks with VoIP equipment.
