AutoProxyConnection

public AutoProxyConnection(SipAccountID account,
                           String defaultTransport)

Creates a new instance of this class. Uses the server from the account.

Parameters:

account - the account of this SIP protocol instance

defaultTransport - the default transport to use when DNS does not provide a protocol through NAPTR or SRV

AutoProxyConnection

public AutoProxyConnection(SipAccountID account,
                           String address,
                           String defaultTransport)

Creates a new instance of this class. Uses the supplied address instead of the server address from the account.

Parameters:

account - the account of this SIP protocol instance

address - the domain on which to perform autodetection

defaultTransport - the default transport to use when DNS does not provide a protocol through NAPTR or SRV

Method Detail

setNetworkUtils

protected void setNetworkUtils(AutoProxyConnection.LocalNetworkUtils nu)

Sets the NetworkUtils wrapper. Used for Unit-Testing.

Parameters:

nu - the the NetworkUtils wrapper.

getNextAddressFromDns

protected boolean getNextAddressFromDns()
                                 throws DnssecException

Description copied from class: ProxyConnection

Implementations must use this method to get the next address, but do not have to care about duplicate addresses.

Specified by:

getNextAddressFromDns in class ProxyConnection

Returns:

True when a further address was available.

Throws:

DnssecException - when a DNSSEC validation failure occured.

reset

public void reset()

Description copied from class: ProxyConnection
