VoIP interconnect: the end of the minute is approaching
More and more voice traffic is migrating from traditional time division multiplexing (TDM) technologies to a multiplicity of different VoIP implementations. Efficient and secure interconnection of these services is essential to providing a voice service with universal reach, but carriers are simply trying to reproduce TDM interconnection models for VoIP. Players must use this opportunity to choose a new interconnection model that enables service and charging innovation rather than stifling it.
