(A) Places a call to (B), (B), The RBT RBT SCP logic looks up (B) (B) in the RBT service database to find out if (B) has a subscription to RBT, and in case this is true, the (A) party will hear the streamed audio until (B) picks up. When (B) picks up, the SCP tells the MSC to break the connection from (A) to the RBT server and instead connect (A) to (B). The resources on the RBT server are now free to deal with other calls. The RBT server is some kind of server equipment that has both a media board (e.g. Dialogic DM3, DNI or Aculab) as well as a connection to the signalling network, either SIGTRAN via TCP/IP, TCP/IP, traditional SS7 link or SIP/H.323 signalling to IMS networks. ISUP is needed for call control, as it is necessary to make a circuit connection to the RBT server. server.
