Technical details
Case I shows the classic flow of the MakeCall functionality. Through the initiation phone number A – the participant in the public phone network – is called first. As soon as the call is picked up, the connection to phone number B – the destination number in the TENIOS network – takes place and the routing plan in the customer portal is executed. 
In Case II a optional special feature comes into action: The implementation of Call Control functions. Call Control offers the possibility to perform automatic outbound actions by the customer-side managing of the call. This can be announcement blocks, forwardings or IVR menues. Please find a detail description of all types available in Call control spec.
