IP1 SMS Call Back

The IP1 Network Call Back Service allows GSM (Global System for Mobile Communications) mobile phone users to initiate long-distance calls by sending an SMS (Short Message Service) text message to an IP1 Network based SMS module equipped with a GSM modem. This allows a GSM user to access our service without an internet connection or IAD device. The SMS message contains the destination number that the user wishes to call. Once the callback server receives the message, it triggers 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.
