This limitation is dependent on the GSM CSD technology used by the mobile phone operator e Delay of the voice Secure phone calls have the characteristics of a voice delay of approximately 1 second similar to satellite communications This characteristics depends on the transmitting technology GSM CSD used by the phone operator In a secure conversation it is therefore useful to create some small breaks in the communication allowing voices to be transmitted before continuing the conversation e Dialtone When calling another PrivateGSM user it will not always be possible to hear the dial tone depending on the type of phone which normally indicates that the other persons phone is ringing However it will always be possible to follow the progress of the communication on the display of the phone 5 1 Making secure phone calls To make a secure phone call with PrivateGSM it is sufficient to digit the secure prefix 801 before the actual phone number including the international prefix of the country you intend to call The called phone number can either be inserted at every new communication or saved in the phonebook including the secure prefix For example to call the phone number 39796020596 it is sufficient to insert the prefix 801 followed by the number transforming the dialed number to 80139796020596 It is important that the dialed number includes both the secure prefix and the country prefix but without including the initial 00
