bool SIPEndPoint::ClearDialogContext ( SIPDialogContext & context )

Parameters:

context

Context for call clearance

bool SIPEndPoint::ClearDialogContext ( const PString & descriptor )

Clear a SIP connection by dialog identifer informataion. This function does not require an OPAL connection to operate, it will attempt to send a BYE to the dialog identified by the information in the SIPDialogContext structure.

This feature can be useful for servers that had an "unexpected exit" and various clients it was talking to at the time do not implement the RFC4028 session timers, so continue to try and send media forever. They need to be told to cease and desist.

Parameters:

descriptor

Descriptor string for call clearance

		unsigned int	options = `0`,
		OpalConnection::StringOptions *	stringOptions = `NULL`
	)			`[virtual]`

Create a connection for the SIP endpoint. The default implementation is to create a OpalSIPConnection.

Parameters:

		PSafetyMode	mode = `PSafeReadWrite`
	)			`[inline]`

virtual PString SIPEndPoint::GetUserAgent ( ) const [virtual]

Get the User Agent for this endpoint. Default behaviour returns an empty string so the SIPConnection builds a valid string from the productInfo data.

These semantics are for backward compatibility.

virtual void SIPEndPoint::HandlePDU ( OpalTransport & transport ) [virtual]

virtual PBoolean SIPEndPoint::IsAcceptedAddress ( const SIPURL & toAddr ) [virtual]

PBoolean SIPEndPoint::IsRegistered	(	const PString &	aor,
		bool	includeOffline = `false`
	)

Determine if there is a registration for the entity. The "token" parameter string is typically the string returned by the Register() function which is guaranteed to uniquely identify the specific registration.

For backward compatibility, the AOR can also be used, but as it is possible to have two registrations to the same AOR, this should be avoided.

The includeOffline parameter indicates if the caller is interested in if we are, to the best of our knowledge, currently registered (have had recent confirmation) or we are not sure if we are registered or not, but are continually re-trying.

Parameters:

aor	AOR returned by Register()
includeOffline	Include offline registrations

bool SIPEndPoint::IsSubscribed	(	const PString &	eventPackage,
		const PString &	aor,
		bool	includeOffline = `false`
	)

Parameters:

eventPackage	Event package being unsubscribed
aor	Address-of-record for subscription
includeOffline	Include offline subscription

bool SIPEndPoint::IsSubscribed	(	const PString &	aor,
		bool	includeOffline = `false`
	)

Returns true if the endpoint is subscribed to some event for the given to address. The includeOffline parameter indicates if the caller is interested in if we are, to the best of our knowlegde, currently subscribed (have had recent confirmation) or we are not sure if we are subscribed or not, but are continually re-trying.

Parameters:

aor	AOR returned by Subscribe()
includeOffline	Include offline subscription

virtual PSafePtr<OpalConnection> SIPEndPoint::MakeConnection	(	OpalCall &	call,
		const PString &	party,
		void *	userData,
		unsigned int	options,
		OpalConnection::StringOptions *	stringOptions
	)			`[virtual]`

Set up a connection to a remote party. This is called from the OpalManager::MakeConnection() function once it has determined that this is the endpoint for the protocol.

The general form for this party parameter is:

[proto:][alias@][transport$]address[:port]

where the various fields will have meanings specific to the endpoint type. For example, with H.323 it could be "h323:Fred@site.com" which indicates a user Fred at gatekeeper size.com. Whereas for the PSTN endpoint it could be "pstn:5551234" which is to call 5551234 on the first available PSTN line.

The proto field is optional when passed to a specific endpoint. If it is present, however, it must agree with the endpoints protocol name or PFalse is returned.

This function usually returns almost immediately with the connection continuing to occur in a new background thread.

If PFalse is returned then the connection could not be established. For example if a PSTN endpoint is used and the assiciated line is engaged then it may return immediately. Returning a non-NULL value does not mean that the connection will succeed, only that an attempt is being made.

The default behaviour is pure.

Parameters:

call	Owner of connection
party	Remote party to call
userData	Arbitrary data to pass to connection
options	options to pass to conneciton
stringOptions	complex string options

Implements OpalEndPoint.

virtual void SIPEndPoint::OnReleased ( OpalConnection & connection ) [virtual]

A call back function whenever a connection is broken. This function can do any internal cleaning up and waiting on background threads that may be using the connection object.

Note that there is not a one to one relationship with the OnEstablishedConnection() function. This function may be called without that function being called. For example if MakeConnection() was used but the call never completed.

Classes that override this function should make sure they call the ancestor version for correct operation.

An application will not typically call this function as it is used by the OpalManager during a release of the connection.

The default behaviour removes the connection from the internal database and calls the OpalManager function of the same name.

connection

Connection that was established

Registration function for backward compatibility.

bool SIPEndPoint::Register	(	const SIPRegister::Params &	params,
		PString &	aor
	)

Register an entity to a registrar. This function is asynchronous to permit several registrations to occur at the same time. It can be called several times for different hosts and users.

The params.m_addressOfRecord field is the only field required, though typically params.m_password is also required. A registration for the user part of params.m_addressOfRecord is made to the a registrar associated with the domain part of the field. The authentication identity is the same as the user field, though this may be set to soemthing different via the params.m_authID field.

The params.m_registrarAddress may indicate the specific hostname to use for the registrar rather than using the domain part of params.m_addressOfRecord field.

To aid in flexbility if the params.m_addressOfRecord does not contain a domain and the params.m_registrarAddress does, the the AOR is constructed from them.

The params.m_realm can be specified when registering, this will allow to find the correct authentication information when being requested. If no realm is specified, authentication will occur with the "best guess" of authentication parameters.

The Contact address is normally constructed from the listeners active on the SIPEndPoint. This may be overridden to an explicit value via the params.m_contactAddress field.

The returned "token" is a string that can be used in functions such as Unregister() or IsRegistered(). While it possible to use the AOR for those functions, it is not recommended as a) there may be more than one registration for an AOR and b) the AOR may be constructed from

virtual PBoolean SIPEndPoint::SetupTransfer	(	const PString &	token,
		const PString &	callIdentity,
		const PString &	remoteParty,
		void *	userData = `NULL`
	)			`[virtual]`

Setup a connection transfer a connection for the SIP endpoint.

Parameters:

token	Existing connection to be transferred
callIdentity	Call identity of the secondary call (if it exists)
remoteParty	Remote party to transfer the existing call to
userData	user data to pass to CreateConnection

void SIPEndPoint::SetUserAgent ( const PString & str ) [inline]

Set the User Agent for the endpoint.

virtual void SIPEndPoint::ShutDown ( ) [virtual]

Shut down the endpoint, this is called by the OpalManager just before destroying the object and can be handy to make sure some things are stopped before the vtable gets clobbered.

Reimplemented from OpalEndPoint.

bool SIPEndPoint::Subscribe	(	SIPSubscribe::PredefinedPackages	eventPackage,
		unsigned	expire,
		const PString &	aor
	)

Parameters:

eventPackage	Event package being unsubscribed
expire	Expiry time in seconds
aor	Address-of-record for subscription

bool SIPEndPoint::Subscribe	(	const SIPSubscribe::Params &	params,
		PString &	token,
		bool	tokenIsAOR = `true`
	)

Subscribe to an agent to get event notifications. This function is asynchronous to permit several subscriptions to occur at the same time. It can be called several times for different hosts and users.

The params.m_eventPackage and params.m_addressOfRecord field are the only field required, though typically params.m_password is also required. A subscription for the user part of params.m_addressOfRecord is made to the an agent associated with the domain part of the field. The authentication identity is the same as the user field, though this may be set to soemthing different via the params.m_authID field.

The params.m_agentAddress may indicate the specific hostname to use for the registrar rather than using the domain part of params.m_addressOfRecord field.

To aid in flexbility if the params.m_addressOfRecord does not contain a domain and the params.m_agentAddress does, the the AOR is constructed from them.

The params.m_realm can be specified when subcribing, this will allow to find the correct authentication information when being requested. If no realm is specified, authentication will occur with the "best guess" of authentication parameters.

The Contact address is normally constructed from the SIPEndPoint local identity.

The returned "token" is a string that can be used in functions such as Unregister() or IsRegistered(). While it possible to use the user supplied AOR for those functions, it is not recommended as a) there may be more than one registration for an AOR and b) the AOR may be constructed from fields in the params argument and not be what the user expects.

The tokenIsAOR can also be used, if false, to return the globally unique ID used for the handler. This is the preferred method, even though the default is to not use it, that is for backward compatibility reasons.

Parameters:

params	Subscription parameters
token	Resultant token for unsubscribe
tokenIsAOR	Token is the address-of-record

bool SIPEndPoint::Unregister ( const PString & aor )

Unregister the address-of-record from a registrar. The "token" parameter string is typically the string returned by the Register() function which is guaranteed to uniquely identify the specific registration.

For backward compatibility, the AOR can also be used, but as it is possible to have two registrations to the same AOR, this should be avoided.

Parameters:

aor

AOR returned by Register()

bool SIPEndPoint::UnregisterAll ( )

Unregister all current registrations. Returns true if at least one registrar is unregistered.

bool SIPEndPoint::UnsubcribeAll ( const PString & eventPackage )

Parameters:

eventPackage

Event package being unsubscribed

bool SIPEndPoint::UnsubcribeAll ( SIPSubscribe::PredefinedPackages eventPackage )

Unsubscribe all current subscriptions. Returns true if at least one subscription is unsubscribed.

Parameters:

eventPackage

Event package being unsubscribed

bool SIPEndPoint::Unsubscribe	(	const PString &	eventPackage,
		const PString &	aor
	)

Parameters:

eventPackage	Event package being unsubscribed
aor	Address-of-record for subscription

bool SIPEndPoint::Unsubscribe	(	SIPSubscribe::PredefinedPackages	eventPackage,
		const PString &	aor
	)

Parameters:

eventPackage	Event package being unsubscribed
aor	Address-of-record for subscription

bool SIPEndPoint::Unsubscribe ( const PString & aor )

Unsubscribe a current subscriptions. The "token" parameter string is typically the string returned by the Subscribe() function which is guaranteed to uniquely identify the specific registration.

For backward compatibility, the AOR can also be used, but as it is possible to have two susbcriptions to the same AOR, this should be avoided.

Parameters:

aor

Unique token for registration
