DETECTION OF UNANSWERED CALL IN ORDER TO GIVE CALLING PARTY THE OPTION TO ALTERNATIVELY DICTATE A TEXT MESSAGE FOR DELIVERY TO THE CALLED PARTY.

摘要

A network based service manages unanswered calls to telephone numbers. The network picks up the call before it 'fails' (e.g. hits a busy tone, rings out, phone is off, phone cannot connect); this can be before or upon or shortly after the network decides to terminate ringtone or to not offer any ringtone. The network then plays back an IVR recording giving the option of speaking a text (SMS, MMS, email, IM etc) to the person they were trying to call. So the caller always gets through to something useful and which may also be seen as les formal than ordinary voicemail, and hence more likely to be used.
