Member Function Documentation

PBoolean H323GatekeeperCall::AddCallCreditServiceControl ( H225_ArrayOf_ServiceControlSession & serviceControl ) const

Add call credit and duration information to PDU.

Comparison H323GatekeeperCall::Compare ( const PObject & obj ) const

Compare two objects.

Parameters

obj	Other object

virtual PBoolean H323GatekeeperCall::Disengage ( int reason = -1 )

virtual

Shut down a call. This sendsa DRQ to the endpoint(s) to close the call down.

Parameters

reason Reason for disengage

const PTime& H323GatekeeperCall::GetAlertingTime ( ) const

inline

References alertingTime.

unsigned H323GatekeeperCall::GetBandwidthUsed ( ) const

inline

References bandwidthUsed.

virtual PString H323GatekeeperCall::GetCallCreditAmount ( ) const

virtual

Get the current credit for this call. This function is only called if the client indicates that it can use the information provided.

The default behaviour calls the same function on the endpoint.

virtual PBoolean H323GatekeeperCall::GetCallCreditMode ( ) const

virtual

Get the call credit billing mode for this endpoint. This function is only called if the client indicates that it can use the information provided.

The default behaviour calls the same function on the endpoint.

H323Connection::CallEndReason H323GatekeeperCall::GetCallEndReason ( ) const

inline

References callEndReason.

const PTime& H323GatekeeperCall::GetCallEndTime ( ) const

inline

References callEndTime.

const OpalGloballyUniqueID& H323GatekeeperCall::GetCallIdentifier ( ) const

inline

References callIdentifier.

unsigned H323GatekeeperCall::GetCallReference ( ) const

inline

References callReference.

const PTime& H323GatekeeperCall::GetCallStartTime ( ) const

inline

References callStartTime.

const OpalGloballyUniqueID& H323GatekeeperCall::GetConferenceIdentifier ( ) const

inline

References conferenceIdentifier.

const PTime& H323GatekeeperCall::GetConnectedTime ( ) const

inline

References connectedTime.

PString H323GatekeeperCall::GetDestinationAddress ( ) const

const PStringArray& H323GatekeeperCall::GetDestinationAliases ( ) const

inline

References dstAliases.

const H323TransportAddress& H323GatekeeperCall::GetDestinationHost ( ) const

inline

References dstHost.

const PString& H323GatekeeperCall::GetDestinationNumber ( ) const

inline

References dstNumber.

virtual unsigned H323GatekeeperCall::GetDurationLimit ( ) const

virtual

Get the duration limit for this call. This function is only called if the client indicates that it can use the information provided.

The default behaviour returns zero which indicates there is no duration limit applicable.

H323RegisteredEndPoint& H323GatekeeperCall::GetEndPoint ( ) const

inline

References endpoint.

H323GatekeeperServer& H323GatekeeperCall::GetGatekeeper ( ) const

inline

References gatekeeper.

const PTime& H323GatekeeperCall::GetLastInfoResponseTime ( ) const

inline

References lastInfoResponse.

PString H323GatekeeperCall::GetSourceAddress ( ) const

const PStringArray& H323GatekeeperCall::GetSourceAliases ( ) const

inline

References srcAliases.

const H323TransportAddress& H323GatekeeperCall::GetSourceHost ( ) const

inline

References srcHost.

const PString& H323GatekeeperCall::GetSourceNumber ( ) const

inline

References srcNumber.

PBoolean H323GatekeeperCall::IsAnsweringCall ( ) const

inline

References AnsweringCall, and direction.

virtual H323GatekeeperRequest::Response H323GatekeeperCall::OnAdmission ( H323GatekeeperARQ & request )

virtual

Handle an admission ARQ PDU. The default behaviour sets some internal variables from the ARQ data and then calls OnResolveAdmission, if necessary, and OnReplyAdmission every time.

virtual void H323GatekeeperCall::OnAlerting ( )

virtual

Call back when an info response detects an Alerting.

virtual H323GatekeeperRequest::Response H323GatekeeperCall::OnBandwidth ( H323GatekeeperBRQ & request )

virtual

Handle a bandwidth BRQ PDU. The default behaviour adjusts the bandwidth used by the gatekeeper and adjusts the remote endpoint according to those limits.

virtual void H323GatekeeperCall::OnConnected ( )

virtual

Call back when an info response detects an Connected.

virtual H323GatekeeperRequest::Response H323GatekeeperCall::OnDisengage ( H323GatekeeperDRQ & request )

virtual

Handle a disengage DRQ PDU. The default behaviour simply returns true.

virtual PBoolean H323GatekeeperCall::OnHeartbeat ( )

virtual

Function called to do heartbeat check of the call. Monitor the state of the call and make sure everything is OK.

A return value of false indicates the call is to be closed for some reason.

Default behaviour checks the time since the last received IRR and if it has been too long does an IRQ to see if the call (and endpoint!) is still there and running. If the IRQ fails, false is returned.

virtual H323GatekeeperRequest::Response H323GatekeeperCall::OnInfoResponse	(	H323GatekeeperIRR &	request,
		H225_InfoRequestResponse_perCallInfo_subtype &	call
	)

virtual

Handle an info request response IRR PDU. The default behaviour resets the heartbeat time monitoring the call.

void H323GatekeeperCall::PrintOn ( ostream & strm ) const

Print the name of the gatekeeper.

Parameters

strm	Stream to print to.

virtual PBoolean H323GatekeeperCall::SendCallCreditServiceControl ( )

virtual

Send the call credit service control PDU. This will send an SCI pdu to the endpoint with the control service session information for the current call credit, if enabled.

virtual PBoolean H323GatekeeperCall::SendServiceControlSession ( const H323ServiceControlSession & session )

virtual

Send the service control session for the PDU. This will send an SCI pdu to the endpoint with the control service session information provided.

PBoolean H323GatekeeperCall::SetBandwidthUsed ( unsigned bandwidth )
