Callhandler (IVR)

The Call Handler answers call, welcomes and greets callers, and fills them in with new information and available options, as well as takes messages and routes calls. It receives signal from SGW/MGW (or directly from G/MSC) and handle calls. Call Handler answers a call, disconnect the call and perform some actions during the call depending on user activities. Call handler can play audio files while a call is connected, so that user listen some music, any types of pre-recorded content or prompts. It also has the functionality of recoding the conversation of a connected call.


Besides, the Call handler module can be integrated with two other submodules: Automated Outbound Dialer (OBD) and IVR Service Creation tool. So, you can develop and deploy Outbound and Inbound service flows in an easy VISIO tool equipped with various built-in service flow components.
