8.13 Automatic RedXREDIAL
The command allows enabling of automatic redialing if the called party was busy. For this purpose the
command uses the <mode> parameter in order to enable or disable this function. If the function is enabled,
the MS executes after the first unsuccessful attempt to establish a voice call link a lot of further attempts; the
amount of failed repeat attempts is limited by the reason of failure. If the user is busy or the destination is
temporary not obtainable, 10 repeat attempts are allowed; but there are also serious circumstances which
make destination permanent unreachable as unknown or changed numbers – in this case only one repeat
attempt is allowed (s. GSM02.07 annex A). If more then 8 failed call attempts exist, the corresponding phone
number is stored in the blacklist.
