The SMS Callback Service allows mobile phone users to make VOIP calls by sending SMS (Short Message Service) message to our Asterisk/Callback Server. This SMS message typically contains the destination number that user wish to call. Once the CallBack server receives the message, it initiates a callback to the user's mobile phone or to any other number specified by the user. Once the user answers, the callback server automatically dials the destination number and connects both calls together.
The SMS Callback module need including Server side scripts implementations.
