ESPONSES
In order to determine the call state of the A3LA-R, the +CLCC and +CPAS commands may be
used. Table 20 demonstrates how the output of the two commands, as well as the Extended
Ring Message, can be combined to provide a more detailed definition of the call state than any
one of the results provides by itself.
