Introduction
. In principal, the registered caller send a SMS message which indicate the destination number they wish to call. Within a short while, the caller will receive a callback from our callback system with the called party connected. In short, the caller needs only their registered mobile phone to send SMS message to trigger a call. By using the SMS callback service the caller can always enjoy the discounted or free incoming-call rates in any other part of the world.

Conference Call

NEW Multi-party conference up to 6 people Send "Conf num1 num2 num3 num4 num5 num6". numx = telephone numbers. Receive call back and get connected to everyone. (* Singapore SMS gateway only)

To call and add new party in the on-going conference, send "add num1" during the
conference. Sending SMS while talking could be tricky. If you want to receive your first call back to alternate phone, you can use "confp num1 num2 num3". Then you will get the first call back to the 'num1' instead of your mobile.

This way, you can free up your mobile phone for another SMS, if needed.
