Intel IP Media Server 5.6 Typical Scenario

42 IP Media Server for HMP Demo Guide — July 2005

Demo Details

5.5.5 TSUsrEvent Structure

The TSUsrEvent structure is used by the demo modules to return event processing results to the

event router.

The TSUserEvt structure is defined as follows:

typedef struct

{

int event;

TDeviceType destination;

int lineDevice;

long xmitSlot;

long neighborDevice;

char dialString[MAX_STRING_LENGTH]}

TSUserEvent;

The fields of the TSUserEvt structure are described as follows:

event

the name of a user-defined event, such as USR_CONNECTED, USR_SENDFAX, etc.

destination

the name of the module that this event is destined for. Possible vavues are IP, VOICE, FAX, or

NONE.

lineDevice

the device handle in this module. It will be later used by the Event Router as an index to find its

counterpart in the destination module.

xmitSlot

an integer that normally indicates a time slot number

neighborDevice

the neighbor device handle

dialString

a char string that is normally filled with a DTMF dialing string

5.6 Typical Scenario

This section describes a typical scenario for sending a fax, which involves all the IP Media Server

demo modules.

Call Offered

When an incoming call is received by the server, the IP module answers the call until the call is

connected.
