VoLTE and GSM subscribers can use this service to automatically reject calls (this can include video calls as well as voice). A message is played to callers and the call is then diverted to voicemail.
Subscribers can activate the service via an IVR service, text message or using USSD on mobile, or via a widget on smart-phones. When activating the service, subscribers can optionally select a specific message or record their own, and can optionally set the duration so it automatically turns off after a set period. Alternatively, using the same methods for activation the subscriber can de-activate the service.
For mobile users, the system can send SMS alerts if the service has been active for a long time (in case the subscriber has forgotten it is active) and to pre-warn subscribers that have set the duration that it will automatically de-activate unless they extend the period.
This service can be enhanced by adding a personalised VIP whitelist – so important calls still get through.
