The ECT technology allows every mobile subscriber to decide what each caller hears before the subscriber answers his/her call. Instead of just the standard ring back tone, the caller can hear a personal message or a hit song with the standard ring back tone in the background. The mobile subscriber can set up his/her personal ring back tones using several, user-friendly interfaces.

ECT's technology offers mobile carriers several ways of billing the service, from a monthly fee to transaction-based charges. Mobile carriers interested in this previously unknown service can also take advantage of ECT's business case consulting.

ECT realizes customized and highly scalable solutions for Ring Back Tone Application based on either their AutoCarrier^® Softswitch or their INtellECT^® Intelligent Network (IN). The ECT solution includes the user portals, an interface for content providers, a complete data warehousing and mediation device as well as the billing interfaces. In particular, ECT is proud of the user interfaces: interactive voice response (IVR), an SMS interface, WAP portals and web portals are all available. The subscriber can use any of these interfaces to set up the service and assign specific ring back tones to specific callers or groups of callers. ECT provides mobile carriers with their own individual Ring Back Tone Application in under 12 weeks, including the portals tailored to each carrier's specification as well as the integration of the ECT technology in the existing mobile network architecture.
