ISDN_ALERT.ISDN_REQ --
ISDN call compatibility request
Synopsis
#include <sys/stream.h>
#include <sys/mdi.h>
#include <sys/types.h>
#include <sys/scoisdn.h>
typedef struct isdn_alert_req
{
isdnPLCI_t plci;
isdnAddInfo_t info;
} isdn_alert_req_t;
Description
The ISDN_ALERT.ISDN_REQ message consists of one
M_PROTO(D7str)
message block indicating an application's compatibility to an
incoming call. The application will send an
ISDN_ALERT.ISDN_REQ message to the network to prevent
the call from expiring (no user responding). If an application
is able to accept the call immediately, it is not necessary to
use this message; the application can immediately issue a
ISDN_CONNECT.ISDN_RESP(D7isdn)
message to the driver.
Parameters
plci
-
Physical Link Connection Identifier; see
isdnPLCI(D4isdn).
info
-
additional information elements; see
isdnInfo(D4isdn).
This parameter should be coded as an empty structure if no
additional information (for example, user data) has to be
transmitted.
