A network based service manages unanswered calls to telephone numbers. Th e 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 shor tly after the network decides to terminate ringtone or to not offer any ring tone. The network then plays back an IVR recording giving the option of spea king 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 b e seen as les formal than ordinary voicemail, and hence more likely to be us ed. |
