In 4Q07, vendors shipped an estimated 9.8 million VoIP Subscriber Feature Server licenses for deployment in service provider networks, generating $177.4 million in revenue. The number of lines is up by 34% Q-o-Q. The growth is due to high VoBB activity in Europe and among Cable MSOs in North America. In Asia-Pacific VoBB growth is still confined to Japan mostly.
Carrier VoIP equipment market has had a great 4Q07 across most equipment categories. Carrier spending, it seems, was pushed back to later part of 2007. That was reflected in Q4 results for the industry as whole.
In 4Q07, Nokia Siemens Networks (NSN) led the VoIP subscriber lines equipment market on a worldwide basis with a market share of 19.1 percent. That lead is followed by Cisco at number 2 and Italtel at number 3 worldwide.
Within the 9.8m VoIP subscriber licenses sold during 4Q07, business centrex lines account for over 1.2 million. The remaining 8.6 million were mainly deployed for residential VoBB or switch replacement.
