<p>An IN service Free Divert to Voice Mail FDTVM is a method of routing a call back to the voice mailbox of a called B-party when the B-party is roaming in a foreign network and a call forwarding service CF to the B-party's voice mailbox has been activated by the called party, which is established in the Service Control Point SCP of the home network HPLMN of the B-party, comprising a MTC-instance and a CF-instance, wherein the FDTVM service executes the following steps when the call is routed back from the foreign network VPLMN:
- triggering the IN service FDTVM by the core network, if the call comes from a foreign network and it is a call forwarding call,
- releasing the call by the CF-instance,
- signaling the call release to the MTC-instance, and
- routing the call directly to the voice mailbox by the MTC-instance.</p> |
