3.2.2 Identify the Caller

The GM862-GPS is able to identify the caller number and give indication of it before the call is

answered.

The calling number is presented after each RING or +CRING indication in the format:

+CLIP: "<number>",<type>[,"<subaddress>",<satype>[,"<alpha>"[,<CLI validity>]]]

where:

<Number> is the phone number;

<type> is the type of number:

145 – international numbering scheme

129 – national numbering scheme

<subaddress> is the subaddress of the calling party

<satype> is the type of subaddress

<alpha> is an optional string type alphanumeric representation of <number> corresponding to

the entry found in phonebook;

<CLI validity> is the validity status of CLI presentation:

0 CLI valid.

1 CLI has been withheld by the originator.

2 CLI is not available due to interworking problems or limitation or originating

network.

In order to use this feature you must enable the caller ID indication presentation, if feature is disabled

then no CLI indication is given after the RING or +CRING code.
