Session border controller, IMS core revenues jump 23 percent, says research firm

The session border controller market is seeing benefits from the increased adoption of SIP trunking and emerging wireless Voice over LTE (VoLTE) services. According to a new Dell'Oro Group report, SBC and IMS Core revenues together rose nearly 23 percent year-over-year.

Although consumer and business usage of voice services on a per-usage basis continues to decline, Chris DePuy, VP of carrier IP telephony research at Dell'Oro Group, said in a release that VoLTE, voice over Wi-Fi, SIP trunking and the service provider movement to carry VoIP "are expected to push growth in Session Border Controllers, Voice Application Servers and IMS Core."
