The Dell (News - Alert)'Oro Group provides research and analysis of the networking and telecommunications industries. Its Carrier IP Telephony Quarterly Report shows the state of those markets each quarter with coverage of revenue, shipments, and the selling prices of items in wired and wireless markets.

The report released for the third quarter of 2014 shows that the carrier IP telephony market grew three percent compared to the third quarter of 2013. It shows that the overall revenue present within the market segments of IP multimedia subsystems, voice application servers, and session border controllers have nearly reached the $1 billion mark for the quarter; the research suggests that the overall revenue came within $50 million of that capstone. Revenue for the quarter for the entire carrier IP telephony market reached nearly $1.7 billion.

Chris DePuy, vice president of Carrier IP Telephony research at Dell'Oro Group, explains in his company's summary of the report that growth has taken place largely within infrastructure changes and multiple communications services through advanced infrastructures.

“We are seeing operators expand their service offerings to deliver multiple services on shared infrastructures, resulting in significant interoperability benefits to customers and increasing leverage on network investments,” DePuy said.

The IP multimedia subsystem (IMS) is now dominating the market by creating an infrastructure where service providers can bring several types of content across a single IP system. This may include high-definition voice and rich communications services such as advanced messaging and video calling. The networks that carry this information are primarily voice over LTE (News - Alert) (VoLTE) and voice over Wi-Fi (VoWIFI). The latter, DePuy points out, has the advantage of providing increased coverage from within buildings.

TMC (News - Alert)'s Conferencing Zone, late this summer, covered the news of Verizon (News - Alert)'s new Advanced Calling system that brings high-definition voice and video to its customers. Verizon's new VoLTE service makes this type of communication possible. Mobility Tech Zone pointed out, previously, that AT&T (News - Alert) was getting in on the game as well. Soon, it seems, the U.S. will have its fair share of choices for the types of services Dell'Oro suggests are climbing in the charts.
