INTERVIEW: Telecom carriers are beginning to deploy IMS (IP multimedia subsystem) technology in their networks instead of buying VoIP equipment.
VoIP.biz-news spoke to Mavenir Systems, a provider of converged voice and messaging solutions, about the opportunities and challenges faced in delivering next generation communications.

VoIP equipment purchases are decreasing at the expense of spending on the deployment of IMS (IP multimedia subsystem) technology, according to Infonetics Research.
Worldwide sales of IMS equipment, including HSS (home subscriber servers), CSCF servers, and voice application servers, are forecast to jump 74 per cent in 2009 over 2008.

The worldwide market for carrier VoIP equipment has stalled after a pro-longed period of double-digit annual revenue growth that began in 2002.
This led to the market contracting for the first time ever in 2008, with a drop in revenue of 6 per cent, according to Infonetics Research.
