Calls can be managed on an individual basis and the R&S®NC VoIP router supports the services known from the ISDN network:
- With call hold the user can place an active call into a wait state. In this state the user can make a call to another person, for example.
- Establishing an additional call while a call is on hold is referred to as consulting. This call can be ended again and the conversation with the call on hold continued.
- With swap call, the user can switch to and fro between two connections. The user is only connected with one caller at a time, while the other caller is put on hold.
- With call swap the user switches an active call over to another call which is on hold. The two callers are then connected and the user is no longer involved in the call. A subscriber forwarding a call can either directly hand over an active call to a third subscriber (unattended call transfer), or a separate call can be made to a third subscriber to communicate the call and then forward it (attended call transfer).
