The purpose of this feature is to allow the user to call a number that is pre-registered in the phone. The call will be placed as it is unhooked ( when you use handset, headset or handsfree). This behaviour will remain the same as long as it is not disabled by APS. This functionality can be used to emit emergency calls. In this case, the user is directly directed towards an urgent number when he pickups the phone. For example, this can be used in an elevator which is blocked. 2.1 Feature activation APS is currently used to activate/deactivate this feature, via the parameters described in next paragraph. 2.2 Keyword definition and usage The parameters governing this feature, both included in the [ipp] section, are: Autocall Values : 0 or 1 Meaning : 0 : Autocall feature is disabled 1 : Autocall feature is enabled AutocallNumber Value : character string Meaning : the string represents the phone number or URI to be called
