Description
The cc_ReqANI( ) function returns the caller ID for Automatic Number
Identification (ANI)-on-demand services. The caller ID is usually included in the
ISDN setup message. However, if the caller ID does not exist and the serving
network is AT&T, the driver will automatically request the caller ID from the
network if the ANI-on-demand feature is enabled. The information is returned in a
NULL terminated ASCII string.
Parameter Description
crn:
The call reference number. Each call needs a CRN.
ani_buf:
The address of the buffer where ANI information is stored.
reqtype:
The type of information requested. Possible values are:
• ISDN_CPN_PREF - calling party number preferred
• ISDN_BN_PREF - billing number preferred
• ISDN_CPN - calling party number only
• ISDN_BN - billing number only
• ISDN_CA_TSC - special uses
mode:
Specifies asynchronous (EV_ASYNC) or synchronous
(EV_SYNC) mode.

multitasking function. It is a multitasking function when the caller number is
offered upon request and the network provides this type of service (such as
