The Dell’ (News - Alert)Oro Group’s goal is to provide timely, reliable data concerning networking, IT and the telecommunications industries with in-depth, objective research and analysis. In addition to market research, Dell’Oro also provides quarterly reports and five year forecasts. This week, we have the latest five year report entitled “Carrier IP Telephony 5-Year Forecast Report.”
The purpose of this forecast is to attempt to find answers to questions such as:
The results of the report show that that spending on emerging voice-related systems such as Session Border Controllers (SBCs), IP Multimedia Subsystem (News - Alert) (IMS) Core and Voice Applications Servers (VASs) will significantly grow over the next five years. According to the five year study, we can expect to see a growth of over 90 percent.
A session border controller (SBC) is a device regularly deployed in Voice over Internet Protocol (VoIP) networks to exert control over the signaling and usually also the media streams involved in setting up, conducting, and tearing down telephone calls or other interactive media communications. The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is an architectural framework for delivering IP multimedia services.Voice Applications Servers are just that.
The fact that service providers are in a transitional phase where they are attempting to replace their existing legacy voice networks with VoIP continues to make this market very active. Service providers will be able to offer new services, many of which will be based on IMS equipment, through VoIP services.
The forecast report includes an analysis and estimate of the following:
Chris DePuy, vice president at Dell'Oro Group, offered the following comments, "New services such as Voice over LTE (VoLTE) and Voice over Wi-Fi are expected to drive robust demand for SBCs, IMS Core and Voice Application Servers in the coming years. These newer systems are expected to replace the existing voice systems that have been used for over a decade. After several years of robust growth of these newer systems, their revenues are now overtaking older system revenue, resulting in our expectation that the overall voice market will remain stable in the coming years."
