Seems like VoIP had a soft quarter after all. In 1Q08, vendors shipped a total of about 7.9 million VoIP Subscriber Feature Server licenses for deployment in service provider networks generating $144 million in revenue. The number of lines is down by 19% Q-o-Q. The 3Q07 and 4Q07 quarters however were unusually high growth quarters for VoIP Subscriber Feature Servers. If the 4Q07 seasonality in particular is normalized, there is a nice sequential growth.
In 1Q08, Nokia Siemens Networks (NSN) led the VoIP subscriber lines equipment market on a worldwide basis with a market share of 19.8 percent. That lead is followed by Italtel at number 2 and Cisco at number 3 worldwide.
Within the 7.9m VoIP subscriber licenses sold during 1Q08, business centrex lines account for over 1.03 million. The remaining 6.87 million were mainly deployed for residential VoBB or 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 in new geographies.
