NexTone Communications (Booth #77062) will debut its new IMX (IP Multimedia Exchange) platform, designed to enable secure and seamless interconnectivity between voice-over-IP (VoIP) networks and networks based on the IP multimedia subsystem (IMS) service delivery framework. With NexTone's IMX, wireline VoIP carriers can now transparently exchange minutes with mobile carriers, deliver fixed mobile convergence (FMC) services and extend the reach of their networks by peering with mobile operators.

When used in conjunction with NexTone's Real-time Session Manager (RSM) platform, which provides call state control and application awareness for IMS networks, the IMX can support QoS for any real-time application spanning converged VoIP and IMS networks.

NexTone's IMX provides a cost-effective way to manage the rapid growth of traffic between wireline carriers and mobile operators, while enabling new business models for network and service expansion. The IMX also can interconnect multiple IMS networks and facilitate the exchange of multimedia traffic between service providers.

The IMX incorporates specialized session awareness to adapt to the requirements of the IMS framework. Key features include network-based policy and call routing, providing end-to-end control of VoIP sessions across networks; advanced SIP features to support mobile gaming, chat and other real-time applications as subscribers roam between networks; transcoding of wire-line codecs on VoIP networks to wireless codecs on IMS networks; and IPv4 to IPv6 network address translation. The IMX also supports SIP over TCP, a requirement for IMS networking.
