Callback Billing Service
Overview
The MX Telecom IVR platform integrates with MX Telecom's SMS Gateway, allowing versatile billing via Premium SMS, especially for situations where a one off charge is more suitable than a per minute charge.
With MX Telecom's Callback Service an end user sends an SMS message into an SMS Short Code with a particular keyword, and then immediately receives one or more billed SMS messages to cover the cost of the call. Once delivery of these messages has been confirmed by MX Telecom, the user will receive a voice call on their mobile phone from the MX Telecom IVR platform. This user has therefore paid for the call before it is initiated.
The number from which the end user receives the call will have the Caller ID witheld, so the end user only associates the service with the Short Code to which they sent an SMS message. Finally, if required, the call would be subject to a forced release after a predetermined period of time (i.e. all calls would be cut off after, say, 5 minutes).
This service is similar to, but not the same as MX Telecom's SMSIVR Billing System, where the end user first calls a number and then receives a Premium SMS which bills them.
The key advantage of the Callback Service is the following:
- Traditional '090' premium rate numbers cannot usually be called from mobile phones; they are often barred by the mobile networks by default. Even if this bar is lifted, end users can still be restricted from making calls to premium rate numbers.
- Mobile phone users can, however, text into any Short Code, which would initiate an outbound call from the MX Telecom IVR platform to the end user. Therefore, numbering ranges are not an issue and tariff limitations are not an issue.
- There are some regulatory issues associated with SMSIVR Billing, which do not apply with SMS Callback services. The Callback service is effectively just a normal Premium SMS service, except that instead of receiving, for example, content via a WAP Push message, the user receives a voice call of a predetermined length.
Further Details
The Callback Billing Service requires Operator Short Codes to receive the inbound message, and an IVR account to make the outbound voice call to the mobile handset.
Callback Billing Service Pricing
For use of the service, there is both a monthly charge and a per minute charge. There is a monthly charge for use of Short Codes to receive the SMS message, and finally the cost of making an outbound call to a mobile handset must be covered. Please see the tables below for more details.
