The platform allows a caller to continue his/her call when he/she has an insufficient account balance. The subscribers can also make collect calls and top up their accounts without breaking their routine. Two services can be used for this purpose:
- «Collect call», available if the recipient is a subscriber of the same MNO; and
- «Promised Payment», provided in other cases; typically the service is temporarily blocked after the account is credited with a certain amount
After the service is selected and confirmed, the call continues without being interrupted.
Key features
- Subscriber-side services management through SMS/USSD/IVR
- Dynamic IVR menu: depends on the availability of each service
- Functions of the «Collect Call» service:
- The outbound call is paid for by the recipient if they are a subscriber of the same MNO. The recipient will be notified of this and be given the option to refuse
- SMS notification of subscribers of other MNOs

- Functions of the «Promised Payment» service:

- SMS notification of the subscriber about the payment status
