/**
* Implementation of SipStack.
*
* The JAIN-SIP stack is initialized by a set of properties (see the JAIN SIP
* documentation for an explanation of these properties
* {@link android.javax.sip.SipStack} ).
*
* For NIST SIP stack all properties can also be passed as JVM system properties
* from the command line as -D arguments.
*
* In addition to these, the following are
* meaningful properties for the NIST SIP stack (specify these in the property
* array when you create the JAIN-SIP statck):
*
*
*
android.gov.nist.javax.sip.TRACE_LEVEL = integer
* Use of this property is still supported but deprecated. Please use
* android.gov.nist.javax.sip.STACK_LOGGER and android.gov.nist.javax.sip.SERVER_LOGGER for
* integration with logging frameworks and for custom formatting of log records.
* This property is used by the built in log4j based logger. You can use
* the standard log4j level names here (i.e. ERROR, INFO, WARNING, OFF, DEBUG,
* TRACE) If this is set to INFO or above, then incoming valid messages are
* logged in SERVER_LOG. If you set this to 32 and specify a DEBUG_LOG then vast
* amounts of trace information will be dumped in to the specified DEBUG_LOG.
* The server log accumulates the signaling trace. This can be viewed using the trace
* viewer tool . Please send us both the server log and debug log when
* reporting non-obvious problems. You can also use the strings DEBUG or INFO
* for level 32 and 16 respectively. If the value of this property is set to
* LOG4J, then the effective log levels are determined from the log4j settings
* file (e.g. log4j.properties). The logger name for the stack is specified
* using the android.gov.nist.javax.sip.LOG4J_LOGGER_NAME property. By default log4j
* logger name for the stack is the same as the stack name. For example,
* properties.setProperty("android.gov.nist.javax.sip.TRACE_LEVEL", "LOG4J");
* properties.setProperty("android.gov.nist.javax.sip.LOG4J_LOGGER_NAME", "SIPStackLogger");
* allows you to now control logging in the stack entirely using log4j
* facilities.
*
*
android.gov.nist.javax.sip.LOG_FACTORY = classpath Use of this
* property is still supported but deprecated. Please use
* android.gov.nist.javax.sip.STACK_LOGGER and android.gov.nist.javax.sip.SERVER_LOGGER for
* integration with logging frameworks and for custom formatting of log records.
*
* The fully qualified classpath for an implementation of the MessageLogFactory.
* The stack calls the MessageLogFactory functions to format the log for
* messages that are received or sent. This function allows you to log auxiliary
* information related to the application or environmental conditions into the
* log stream. The log factory must have a default constructor.
*
*
android.gov.nist.javax.sip.SERVER_LOG = fileName
* Use of this property is still supported but deprecated. Please use
* android.gov.nist.javax.sip.STACK_LOGGER and android.gov.nist.javax.sip.SERVER_LOGGER for
* integration with logging frameworks and for custom formatting of log records.
* Log valid incoming messages here. If this is left null AND the
* TRACE_LEVEL is above INFO (or TRACE) then the messages are printed to stdout.
* Otherwise messages are logged in a format that can later be viewed using the
* trace viewer application which is located in the tools/tracesviewer
* directory. Mail this to us with bug reports.
*
*
android.gov.nist.javax.sip.DEBUG_LOG = fileName Use of this property
* is still supported but deprecated. Please use android.gov.nist.javax.sip.STACK_LOGGER
* and android.gov.nist.javax.sip.SERVER_LOGGER for integration with logging frameworks
* and for custom formatting of log records.
* Where the debug log goes. Mail this to us with bug reports.
*
*
*
android.gov.nist.javax.sip.LOG_MESSAGE_CONTENT = true|false
* Set true if you want to capture content into the log. Default is false. A bad
* idea to log content if you are using SIP to push a lot of bytes through TCP.
*
*
android.gov.nist.javax.sip.LOG_STACK_TRACE_ON_MESSAGE_SEND = true|false
* Set true if you want to to log a stack trace at INFO level for each message
* send. This is really handy for debugging.
*
*
android.gov.nist.javax.sip.STACK_LOGGER = full path name to the class
* implementing android.gov.nist.core.StackLogger interface
* If this property is defined the sip stack will try to instantiate it through
* a no arg constructor. This allows to use different logging implementations
* than the ones provided by default to log what happens within the stack while
* processing SIP messages. If this property is not defined, the default sip
* stack LogWriter will be used for logging
*
*
android.gov.nist.javax.sip.SERVER_LOGGER = full path name to the class
* implementing android.gov.nist.core.ServerLogger interface
* If this property is defined the sip stack will try to instantiate it through
* a no arg constructor. This allows to use different logging implementations
* than the ones provided by default to log sent/received messages by the sip
* stack. If this property is not defined, the default sip stack ServerLog will
* be used for logging
*
*
android.gov.nist.javax.sip.AUTOMATIC_DIALOG_ERROR_HANDLING = [true|false]
*
* Default is true. This is also settable on a per-provider basis. This
* flag is set to true by default. When set
* to false the following behaviors are enabled:
*
*
*
Turn off Merged requests Loop Detection:
* The following behavior is turned off: If the request has no tag in the To header field,
* the UAS core MUST check the request against ongoing transactions. If the From tag, Call-ID, and CSeq
* exactly match those associated with an ongoing transaction, but the request
* does not match that transaction (based on the matching rules in Section
* 17.2.3), the UAS core SHOULD generate a 482 (Loop Detected) response and pass
* it to the server transaction.
*
*
*
*
android.gov.nist.javax.sip.IS_BACK_TO_BACK_USER_AGENT = [true|false]
* Default is false This property controls a setting on the Dialog
* objects that the stack manages. Pure B2BUA applications should set this flag
* to true. This property can also be set on a per-dialog basis.
* Setting this to true imposes serialization on re-INVITE and makes
* the sending of re-INVITEs asynchronous. The sending of re-INVITE is
* controlled as follows : If the previous in-DIALOG request was an invite
* ClientTransaction then the next re-INVITEs that uses the dialog will wait
* till an ACK has been sent before admitting the new re-INVITE. If the previous
* in-DIALOG transaction was a INVITE ServerTransaction then Dialog waits for
* ACK before re-INVITE is allowed to be sent. If a dialog is not ACKed within
* 32 seconds, then the dialog is torn down and a BYE sent to the peer.
*
android.gov.nist.javax.sip.MAX_MESSAGE_SIZE = integer
* Maximum size of content that a TCP connection can read. Must be at least 4K.
* Default is "infinity" -- ie. no limit. This is to prevent DOS attacks
* launched by writing to a TCP connection until the server chokes.
*
*
android.gov.nist.javax.sip.DELIVER_TERMINATED_EVENT_FOR_NULL_DIALOG = [true|false]
* If set to false (the default), the application does NOT get notified when a Dialog in the
* NULL state is terminated. ( Dialogs in the NULL state are not associated with an actual SIP Dialog.
* They are a programming convenience. A Dialog is in the NULL state before the first response for the
* Dialog forming Transaction). If set to true, the SipListener will get a DialogTerminatedEvent
* when a Dialog in the NULL state is terminated.
*
*
*
android.gov.nist.javax.sip.CACHE_SERVER_CONNECTIONS = [true|false]
* Default value is true. Setting this to false makes the Stack close the server
* socket after a Server Transaction goes to the TERMINATED state. This allows a
* server to protectect against TCP based Denial of Service attacks launched by
* clients (ie. initiate hundreds of client transactions). If true (default
* action), the stack will keep the socket open so as to maximize performance at
* the expense of Thread and memory resources - leaving itself open to DOS
* attacks.
*
*
*
android.gov.nist.javax.sip.CACHE_CLIENT_CONNECTIONS = [true|false]
* Default value is true. Setting this to false makes the Stack close the server
* socket after a Client Transaction goes to the TERMINATED state. This allows a
* client release any buffers threads and socket connections associated with a
* client transaction after the transaction has terminated at the expense of
* performance.
*
*
android.gov.nist.javax.sip.THREAD_POOL_SIZE = integer
* Concurrency control for number of simultaneous active threads. If
* unspecificed, the default is "infinity". This feature is useful if you are
* trying to build a container.
*
*
*
If this is not specified, and the listener is re-entrant, each
* event delivered to the listener is run in the context of a new thread.
*
If this is specified and the listener is re-entrant, then the stack will
* run the listener using a thread from the thread pool. This allows you to
* manage the level of concurrency to a fixed maximum. Threads are pre-allocated
* when the stack is instantiated.
*
If this is specified and the listener is not re-entrant, then the stack
* will use the thread pool thread from this pool to parse and manage the state
* machine but will run the listener in its own thread.
*
*
*
android.gov.nist.javax.sip.REENTRANT_LISTENER = true|false
* Default is false. Set to true if the listener is re-entrant. If the listener
* is re-entrant then the stack manages a thread pool and synchronously calls
* the listener from the same thread which read the message. Multiple
* transactions may concurrently receive messages and this will result in
* multiple threads being active in the listener at the same time. The listener
* has to be written with this in mind. If you want good performance on a
* multithreaded machine write your listener to be re-entrant and set this
* property to be true
*
*
android.gov.nist.javax.sip.MAX_CONNECTIONS = integer
* Max number of simultaneous TCP connections handled by stack.
*
*
android.gov.nist.javax.sip.MAX_SERVER_TRANSACTIONS = integer
* Maximum size of server transaction table. The low water mark is 80% of the
* high water mark. Requests are selectively dropped in the lowater mark to
* highwater mark range. Requests are unconditionally accepted if the table is
* smaller than the low water mark. The default highwater mark is 5000
*
*
android.gov.nist.javax.sip.MAX_CLIENT_TRANSACTIONS = integer
* Max number of active client transactions before the caller blocks and waits
* for the number to drop below a threshold. Default is unlimited, i.e. the
* caller never blocks and waits for a client transaction to become available
* (i.e. it does its own resource management in the application).
*
*
android.gov.nist.javax.sip.PASS_INVITE_NON_2XX_ACK_TO_LISTENER = true|false
*
* If true then the listener will see the ACK for non-2xx responses for server
* transactions. This is not standard behavior per RFC 3261 (INVITE server
* transaction state machine) but this is a useful flag for testing. The TCK
* uses this flag for example.
*
*
android.gov.nist.javax.sip.MAX_LISTENER_RESPONSE_TIME = Integer
* Max time (seconds) to wait on the transaction lock used to serialize message delivery.
* Default time is "infinity" - i.e. if the listener never
* responds, the stack will hang on to a reference for the transaction and
* result in a unusable thread stuck waiting for the lock to be released. A good value
* for this property is the lifespan of the transaction or the expected blocking delay in
* the listener.
*
*
android.gov.nist.javax.sip.MAX_TX_LIFETIME_INVITE = Integer
* Defaults -1 : infinite. Typical can be dependent on early dialog timeout by example 3 minutes could be a good default
* Max time (seconds) an INVITE transaction is supposed to live in the stack.
* This is to avoid any leaks in whatever state the transaction can be in even if the application misbehaved
* When the max time is reached, a timeout event will fire up to the application
* listener so that the application can take action and then will be removed from
* the stack after the typical lingering period of 8s in the stack
*
*
android.gov.nist.javax.sip.MAX_TX_LIFETIME_NON_INVITE = Integer
* Defaults -1 : infinite. Typical is dependent on T1 by example 2 * T1 could be a good default
* Max time (seconds) a non INVITE transaction is supposed to live in the stack.
* This is to avoid any leaks in whatever state the transaction can be in even if the application misbehaved
* When the max time is reached, a timeout event will fire up to the application
* listener so that the application can take action and then will be removed from
* the stack after the typical lingering period of 8s in the stack. There is a
* specific property as a non INVITE property is short live as compared to INVITE
* and so can be collected ore eagerly to save up on memory usage
*
*
android.gov.nist.javax.sip.DELIVER_TERMINATED_EVENT_FOR_ACK = [true|false]
*
* Default is false. ACK Server Transaction is a Pseuedo-transaction.
* If you want termination notification on ACK transactions (so all server
* transactions can be handled uniformly in user code during cleanup), then set
* this flag to true.
*
*
android.gov.nist.javax.sip.READ_TIMEOUT = integer
* This is relevant for incoming TCP connections to prevent starvation at the
* server. This defines the timeout in miliseconds between successive reads
* after the first byte of a SIP message is read by the stack. All the sip
* headers must be delivered in this interval and each successive buffer must be
* of the content delivered in this interval. Default value is -1 (ie. the stack
* is wide open to starvation attacks) and the client can be as slow as it wants
* to be.
*
*
android.gov.nist.javax.sip.NETWORK_LAYER = classpath
* This is an EXPERIMENTAL property (still under active devlopment). Defines a
* network layer that allows a client to have control over socket allocations
* and monitoring of socket activity. A network layer should implement
* android.gov.nist.core.net.NetworkLayer. The default implementation simply acts as a
* wrapper for the standard java.net socket layer. This functionality is still
* under active development (may be extended to support security and other
* features).
*
*
android.gov.nist.javax.sip.ADDRESS_RESOLVER = classpath
* The fully qualified class path for an implementation of the AddressResolver
* interface. The AddressResolver allows you to support lookup schemes for
* addresses that are not directly resolvable to IP adresses using
* getHostByName. Specifying your own address resolver allows you to customize
* address lookup. The default address resolver is a pass-through address
* resolver (i.e. just returns the input string without doing a resolution). See
* android.gov.nist.javax.sip.DefaultAddressResolver.
*
*
android.gov.nist.javax.sip.AUTO_GENERATE_TIMESTAMP= [true| false]
* (default is false) Automatically generate a getTimeOfDay timestamp for a
* retransmitted request if the original request contained a timestamp. This is
* useful for profiling.
*
*
android.gov.nist.javax.sip.THREAD_AUDIT_INTERVAL_IN_MILLISECS = long
* Defines how often the application intends to audit the SIP Stack about the
* health of its internal threads (the property specifies the time in
* miliseconds between successive audits). The audit allows the application to
* detect catastrophic failures like an internal thread terminating because of
* an exception or getting stuck in a deadlock condition. Events like these will
* make the stack inoperable and therefore require immediate action from the
* application layer (e.g., alarms, traps, reboot, failover, etc.) Thread audits
* are disabled by default. If this property is not specified, audits will
* remain disabled. An example of how to use this property is in
* src/examples/threadaudit.
*
*
android.gov.nist.javax.sip.NIO_MAX_SOCKET_IDLE_TIME = long
* Defines the number of milliseconds a NIO TCP socket will be kept alive after the
* last IO operation on that socket. This allows to clean up after high initial load
* of new calls that hang up or stay idle. Note that disconnecting the socket does't
* end the SIP call. A new socket will be established when needed for any existing calls
* by the SIP RFC spec.
*
*
*
android.gov.nist.javax.sip.stack.USE_DIRECT_BUFFERS = [true|false]
* Default is true If set to false, the NIO stack won't use direct buffers.
* As Direct buffers reside outside of the heap memory, they can lead to unforeseen out of memory exceptions
* as seen in http://java.net/jira/browse/JSIP-430. This flag allows to use non direct buffers for better memory
* monitoring and management.
*
*
*
android.gov.nist.javax.sip.COMPUTE_CONTENT_LENGTH_FROM_MESSAGE_BODY =
* [true|false]
* Default is false If set to true, when you are creating a
* message from a String, the MessageFactory will compute the content
* length from the message content and ignore the provided content length
* parameter in the Message. Otherwise, it will use the content length supplied
* and generate a parse exception if the content is truncated.
*
*
android.gov.nist.javax.sip.CANCEL_CLIENT_TRANSACTION_CHECKED = [true|false]
*
* Default is true. This flag is added in support of load balancers or
* failover managers where you may want to cancel ongoing transactions from a
* different stack than the original stack. If set to false then the
* CANCEL client transaction is not checked for the existence of the INVITE or
* the state of INVITE when you send the CANCEL request. Hence you can CANCEL an
* INVITE from a different stack than the INVITE. You can also create a CANCEL
* client transaction late and send it out after the INVITE server transaction
* has been Terminated. Clearly this will result in protocol errors. Setting the
* flag to true ( default ) enables you to avoid common protocol errors.
*
*
android.gov.nist.javax.sip.IS_BACK_TO_BACK_USER_AGENT = [true|false]
* Default is false This property controls a setting on the Dialog
* objects that the stack manages. Pure B2BUA applications should set this flag
* to true. This property can also be set on a per-dialog basis.
* Setting this to true imposes serialization on re-INVITE and makes
* the sending of re-INVITEs asynchronous. The sending of re-INVITE is
* controlled as follows : If the previous in-DIALOG request was an invite
* ClientTransaction then the next re-INVITEs that uses the dialog will wait
* till an ACK has been sent before admitting the new re-INVITE. If the previous
* in-DIALOG transaction was a INVITE ServerTransaction then Dialog waits for
* ACK before re-INVITE is allowed to be sent. If a dialog is not ACKed within
* 32 seconds, then the dialog is torn down and a BYE sent to the peer.
*
*
*
android.gov.nist.javax.sip.RECEIVE_UDP_BUFFER_SIZE = int
* Default is 8*1024. This property control the size of the UDP buffer
* used for SIP messages. Under load, if the buffer capacity is overflown the
* messages are dropped causing retransmissions, further increasing the load and
* causing even more retransmissions. Good values to this property for servers
* is a big number in the order of 8*8*1024.
*
*
android.gov.nist.javax.sip.SEND_UDP_BUFFER_SIZE = int
* Default is 8*1024. This property control the size of the UDP buffer
* used for SIP messages. Under load, if the buffer capacity is overflown the
* messages are dropped causing retransmissions, further increasing the load and
* causing even more retransmissions. Good values to this property for servers
* is a big number in the order of 8*8*1024 or higher.
*
*
android.gov.nist.javax.sip.CONGESTION_CONTROL_TIMEOUT = int How
* much time messages are allowed to wait in queue before being dropped due to
* stack being too slow to respond. Default value is 8000 ms. The value is in
* milliseconds
*
*
*
android.gov.nist.javax.sip.TCP_POST_PARSING_THREAD_POOL_SIZE = integer
* Use 0 or do not set this option to disable it.
*
* When using TCP your phones/clients usually connect independently creating their own TCP
* sockets. Sometimes however SIP devices are allowed to tunnel multiple calls over
* a single socket. This can also be simulated with SIPP by running "sipp -t t1".
*
* In the stack each TCP socket has it's own thread. When all calls are using the same
* socket they all use a single thread, which leads to severe performance penalty,
* especially on multi-core machines.
*
* This option instructs the SIP stack to use a thread pool and split the CPU load
* between many threads. The number of the threads is specified in this parameter.
*
* The processing is split immediately after the parsing of the message. It cannot
* be split before the parsing because in TCP the SIP message size is in the
* Content-Length header of the message and the access to the TCP network stream
* has to be synchronized. Additionally in TCP the message size can be larger.
* This causes most of the parsing for all calls to occur in a single thread, which
* may have impact on the performance in trivial applications using a single socket
* for all calls. In most applications it doesn't have performance impact.
*
* If the phones/clients use separate TCP sockets for each call this option doesn't
* have much impact, except the slightly increased memory footprint caused by the
* thread pool. It is recommended to disable this option in this case by setting it
* 0 or not setting it at all. You can simulate multi-socket mode with "sipp -t t0".
*
* With this option also we avoid closing the TCP socket when something fails, because
* we must keep processing other messages for other calls.
*
* Note: This option relies on accurate Content-Length headers in the SIP messages. It
* cannot recover once a malformed message is processed, because the stream iterator
* will not be aligned any more. Eventually the connection will be closed.
*
*
*
android.gov.nist.javax.sip.DELIVER_UNSOLICITED_NOTIFY = [true|false]
* Default is false. This flag is added to allow Sip Listeners to
* receive all NOTIFY requests including those that are not part of a valid
* dialog.
*
*
android.gov.nist.javax.sip.REJECT_STRAY_RESPONSES = [true|false] Default
* is false A flag that checks responses to test whether the response
* corresponds to a via header that was previously generated by us. Note that
* setting this flag implies that the stack will take control over setting the
* VIA header for Sip Requests sent through the stack. The stack will attach a
* suffix to the VIA header branch and check any response arriving at the stack
* to see if that response suffix is present. If it is not present, then the
* stack will silently drop the response.
*
*
android.gov.nist.javax.sip.MAX_FORK_TIME_SECONDS = integer Maximum time for which the original
* transaction for which a forked response is received is tracked. This property
* is only relevant to Dialog Stateful applications ( User Agents or B2BUA).
* When a forked response is received in this time interval from when the original
* INVITE client transaction was sent, the stack will place the original INVITE
* client transction in the ResponseEventExt and deliver that to the application.
* The event handler can get the original transaction from this event.
*
*
android.gov.nist.javax.sip.EARLY_DIALOG_TIMEOUT_SECONDS=integer Maximum time for which a dialog
* can remain in early state. This is defaulted to 3 minutes ( 180 seconds).
*
*
*
android.gov.nist.javax.sip.THREAD_PRIORITY=integer Control the priority of the threads started by the stack.
*
*
*
android.gov.nist.javax.sip.MESSAGE_PARSER_FACTORY = name of the class implementing android.gov.nist.javax.sip.parser.MessageParserFactory
* This factory allows pluggable implementations of the MessageParser that will take care of parsing the incoming messages.
* By example one could plug a lazy parser through this factory.
*
*
android.gov.nist.javax.sip.MESSAGE_PROCESSOR_FACTORY = name of the class implementing android.gov.nist.javax.sip.parser.MessageProcessorFactory
* This factory allows pluggable implementations of the MessageProcessor that will take care of incoming messages.
* By example one could plug a NIO Processor through this factory.
*
*
android.gov.nist.javax.sip.TIMER_CLASS_NAME = name of the class implementing android.gov.nist.javax.sip.stack.timers.SipTimer interface
* This allows pluggable implementations of the Timer that will take care of scheduling the various SIP Timers.
* By example one could plug a regular timer, a scheduled thread pool executor.
*
*
android.gov.nist.javax.sip.DELIVER_RETRANSMITTED_ACK_TO_LISTENER=boolean A testing property
* that allows application to see the ACK for retransmitted 200 OK requests. Note that this is for test
* purposes only
*
*
android.gov.nist.javax.sip.AGGRESSIVE_CLEANUP=booleanDeprecated - use RELEASE_REFERENCES_STRATEGY instead
* A property that will cleanup Dialog, and Transaction structures
* agrressively to improve memroy usage and performance (up to 50% gain). However one needs to be careful in its code
* on how and when it accesses transaction and dialog data since it cleans up aggressively when transactions changes state
* to COMPLETED or TERMINATED and for Dialog once the ACK is received/sent
*
*
android.gov.nist.javax.sip.RELEASE_REFERENCES_STRATEGY=String
* A property that specify the strategy for cleaning up references within the Dialog and Transaction structures. Following options can be used
*
*
None: This is the default. It keeps references to request and responses as part of transactions and dialogs. This consumes the most amount of memory usage
*
Normal: It removes references to request and responses in transactions and dialogs in cleaning them up but keep byte arrays of requests or responses to be able to reparse them if the application need them. This gives a 2x improvement in memory as opposed to None
*
Aggressive: It removes references to request and responses in transactions and dialogs in cleaning them up and don't allow reparsing. Need careful application design. This gives a further improvements in memory as opposed to Normal Strategy and also CPU improvements.
*
*
*
android.gov.nist.javax.sip.PATCH_SIP_WEBSOCKETS_HEADERS=boolean
* A property that specify wether to patch websocket client with .invalid address
*
*
android.gov.nist.javax.sip.ALWAYS_ADD_RPORT=boolean
* A property that specify wether to putch the rport if the peer packet source port is different than the via header one
*
*
android.gov.nist.javax.sip.LINGER_TIMER=int
* A property that will specify for how many seconds the Dialog and Transaction structures will stay in memory before the stack releases them
*
*
*
android.gov.nist.javax.sip.MIN_KEEPALIVE_TIME_SECONDS = integer Minimum time between keep alive
* pings (CRLF CRLF) from clients. If pings arrive with less than this frequency they will be replied
* with CRLF CRLF if greater they will be rejected. The default is -1 (i.e. do not respond to CRLF CRLF).
*
*
*
android.gov.nist.javax.sip.DIALOG_TIMEOUT_FACTOR= integer Default to 64. The number of ticks before a
* dialog that does not receive an ACK receives a Timeout notification. Note that this is only relevant
* if the registered SipListener is of type SipListenerExt
*
*
*
android.gov.nist.javax.sip.SIP_MESSAGE_VALVE= String Default to null. The class name of your custom valve component.
* An instance of this class will be created and the SIPMessageValve.processRequest/Response() methods will be called for every message
* before any long-lived SIP Stack resources are allocated (no transactions, no dialogs). From within the processRequest callback
* implementation you can drop messages, send a response statelessly or otherwise transform/pre-process the message before it reaches
* the next steps of the pipeline. Similarly from processResponse() you can manipulate a response or drop it silently, but dropping
* responses is not recommended, because the transaction already exists when the request for the response was sent.
*
*
*
android.gov.nist.javax.sip.SIP_EVENT_INTERCEPTOR Default to null. The class name of your custom interceptor object.
* An instance of this object will be created at initialization of the stack. You must implement the interface
* android.gov.nist.javax.sip.stack.SIPEventInterceptor and handle the lifecycle callbacks. This interface is the solution for
* https://jain-sip.dev.java.net/issues/show_bug.cgi?id=337 . It allows to wrap the JSIP pipeline and execute custom
* analysis logic as SIP messages advance through the pipeline checkpoints. One example implementation of this interceptor
* is android.gov.nist.javax.sip.stack.CallAnalysisInterceptor, which will periodically check for requests stuck in the
* JAIN SIP threads and if some request is taking too long it will log the stack traces for all threads. The logging can
* occur only on certain events, so it will not overwhelm the CPU. The overall performance penalty by using this class in
* production under load is only 2% peak on average laptop machine. There is minimal locking inside. One known limitation
* of this feature is that you must use android.gov.nist.javax.sip.REENTRANT_LISTENER=true to ensure that the request will be
* processed in the original thread completely for UDP.
*
*
android.gov.nist.javax.sip.TLS_CLIENT_PROTOCOLS = String
* Comma-separated list of protocols to use when creating outgoing TLS connections.
* The default is "TLSv1.2, TLSv1.1, TLSv1".
* It's advisable not to use SSL protocols because of http://googleonlinesecurity.blogspot.fr/2014/10/this-poodle-bites-exploiting-ssl-30.html
*
*
*
android.gov.nist.javax.sip.android.gov.nist.javax.sip.ENABLED_CIPHER_SUITES = String
* Comma-separated list of suites to use when creating outgoing TLS connections.
* The default is "TLS_RSA_WITH_AES_128_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA,
TLS_DH_anon_WITH_AES_128_CBC_SHA,
SSL_DH_anon_WITH_3DES_EDE_CBC_SHA".
*
*
*
*
android.gov.nist.javax.sip.TLS_SECURITY_POLICY = String The fully qualified path
* name of a TLS Security Policy implementation that is consulted for certificate verification
* of outbund TLS connections.
*
*
*
android.gov.nist.javax.sip.TLS_CLIENT_AUTH_TYPE = String Valid values are Default (backward compatible with previous versions)
* , Enabled, Want, Disabled or DisabledAll. Set to Enabled if you want the SSL stack to require a valid certificate chain from the client before
* accepting a connection. Set to Want if you want the SSL stack to request a client Certificate, but not fail if one isn't presented.
* A Disabled value will not require a certificate chain for the Server Connection. A DisabledAll will not require a certificate chain for both Server and Client Connections.
*
*
*
android.gov.nist.javax.sip.RELIABLE_CONNECTION_KEEP_ALIVE_TIMEOUT Value in seconds which is used as default keepalive timeout
* (See also http://tools.ietf.org/html/rfc5626#section-4.4.1). Defaults to "infiinity" seconds (i.e. timeout event not delivered).
*
*
android.gov.nist.javax.sip.SSL_HANDSHAKE_TIMEOUT Value in seconds which is used as default timeout for performing the SSL Handshake
* This prevents bad clients of connecting without sending any data to block the server
*
*
android.gov.nist.javax.sip.SSL_RENEGOTIATION_ENABLED = [true|false] Default value is true. Allow or disallow SSL renegotiation to resolve potential DoS problem -
* reference and another reference. The safe option is to disable it.
*
*
*
javax.net.ssl.keyStore = fileName
* Default is NULL. If left undefined the keyStore and trustStore will
* be left to the java runtime defaults. If defined, any TLS sockets created
* (client and server) will use the key store provided in the fileName. The
* trust store will default to the same store file. A password must be provided
* to access the keyStore using the following property:
*
* properties.setProperty("javax.net.ssl.keyStorePassword", "<password>");
* properties.setProperty("javax.net.ssl.trustStorePassword", "<password>");
*
* If not trustStorePassword is provided then the keyStorePassword will be used for both.
* The trust store can be changed, to a separate file with the following
* setting:
*
* properties.setProperty("javax.net.ssl.trustStore", "<trustStoreFileName location>");
*
* If the trust store property is provided the password on the trust store must
* be the same as the key store.
*
*
* Note that the stack supports the extensions that are defined in
* SipStackExt. These will be supported in the next release of JAIN-SIP. You
* should only use the extensions that are defined in this class.
