Triggering Callback by SMS
Revised 25 March 2005

In a number of countries, incumbent operators continually try to bar CallBack services in order to protect their monopoly. Typical methods of blocking CallBack may be to prevent DTMF digits being sent thereby making it impossible to dial the destination number once you have received the CallBack or by blocking access to the callback number range completely.

The GlobalTel SMS callback service can overcome these issues and is one of the market leaders in this sector.

The basic concept of the service is that a customer sends a text message containing the destination number and within a few seconds receives a CallBack and if requested, connected with any number.

Any delay would be caused by the foreign servers or the Internet system.

SMS INFORMATION FROM GLOBALTEL'S TELECOM GLOSSARY

SMS - Short Message Service. SMS-enabled phones allow users to send and receive short text messages without placing an actual phone call. GlobalTel callback customers can trigger a callback by sending an SMS message to GlobalTel's switch.

SMS provides the ability to receive text on your phone in the form of an alert or an alphanumeric page. For example, Singapore telecom offers Directory Assistance SMS services for its mobile customers - the requested phone number is sent to the customer's mobile phone by SMS as a text message.

SMS is popular in all countries where mobile phone rates are high and is widely used in Europe and Japan. The text messages can be sent to another mobile phone or to an email address. These messages are usually limited to 160 characters, and must be entered on phone keypad.

GlobalTel customers using GlobalTel's callback service, or CallMeBack phone cards, use mobile phone SMS text messaging to trigger callback. The customer can also put in a message to trigger a callback and automatically connect to the destination number. This is referred to as SMS DIRECT DIAL.

This system allows customers to trigger a callback in countries where the local PTT is blocking Callback and is also blocking the customer’s Internet domain so the customer cannot trigger callback by Internet. SMS text messaging sent by mobile phones does not travel by Internet and is not blocked.
