Detailed Description

The QXmppCallManager class provides support for making and receiving voice calls.

Session initiation is performed as described by XEP-0166: Jingle, XEP-0167: Jingle RTP Sessions and XEP-0176: Jingle ICE-UDP Transport Method.

The data stream is connected using Interactive Connectivity Establishment (RFC 5245) and data is transferred using Real Time Protocol (RFC 3550) packets.

To make use of this manager, you need to instantiate it and load it into the QXmppClient instance as follows:

auto *client = new QXmppClient();
auto *callManager = client->addNewExtension<QXmppCallManager>();

XEP-0320: Use of DTLS-SRTP in Jingle Sessions

DTLS-SRTP allows to encrypt peer-to-peer calls. Internally, a TLS handshake is done to negotiate keys for SRTP (Secure RTP). By default DTLS is not enforced, this can be done using setDtlsRequired(), though.

DTLS-SRTP by default exchanges the fingerprint via unencrypted XMPP packets. This means that the XMPP server could potentially replace the fingerprint or prevent the clients from using DTLS at all. However, the actual media connection is typically peer-to-peer, so the XMPP server does not have access to the transmitted data.

Support for DTLS-SRTP is available since QXmpp 1.11.

Constructor & Destructor Documentation

QXmppCallManager()

QXmppCallManager::QXmppCallManager

(

)

Constructs a QXmppCallManager object to handle incoming and outgoing Voice-Over-IP calls.

~QXmppCallManager()

QXmppCallManager::~QXmppCallManager ( )

overridedefault

Destroys the QXmppCallManager object.

Member Function Documentation

call()

QXmppCall * QXmppCallManager::call

(

const QString &

jid

)

Initiates a new outgoing call to the specified recipient.

Parameters

jid

callReceived()

Q_SIGNAL void QXmppCallManager::callReceived

(

QXmppCall *

call

)

This signal is emitted when a new incoming call is received.

To accept the call, invoke the call's QXmppCall::accept() method. To refuse the call, invoke the call's QXmppCall::hangup() method.

dtlsRequired()

bool QXmppCallManager::dtlsRequired

(

)

const

Returns whether the call manager requires encryption using XEP-0320: Use of DTLS-SRTP in Jingle Sessions for all calls.

Since

QXmpp 1.11

setDtlsRequired()

void QXmppCallManager::setDtlsRequired

(

bool

dtlsRequired

)

Sets whether the call manager requires encryption using XEP-0320: Use of DTLS-SRTP in Jingle Sessions for all calls.

Since

QXmpp 1.11

setStunServer()

void QXmppCallManager::setStunServer	(	const QHostAddress &	host,
		quint16	port = 3478
	)

Sets a single STUN server to use to determine server-reflexive addresses and ports.

Note

This may only be called prior to calling bind().

Parameters

host	The address of the STUN server.
port	The port of the STUN server.

setStunServers()

void QXmppCallManager::setStunServers

(

const QList< QPair< QHostAddress, quint16 > > &

servers

)

Sets multiple STUN servers to use to determine server-reflexive addresses and ports.

Note

This may only be called prior to calling bind().

Parameters

servers

List of the STUN servers.

Since

QXmpp 1.3

setTurnPassword()

void QXmppCallManager::setTurnPassword

(

const QString &

password

)

Sets the password used for authentication with the TURN server.

Parameters

password

setTurnServer()

void QXmppCallManager::setTurnServer	(	const QHostAddress &	host,
		quint16	port = 3478
	)

Sets the TURN server to use to relay packets in double-NAT configurations.

Parameters

host	The address of the TURN server.
port	The port of the TURN server.

setTurnUser()

void QXmppCallManager::setTurnUser

(

const QString &

user

)

Sets the user used for authentication with the TURN server.

Parameters

user
