Builds a url

PBoolean IAX2EndPoint::ConectionForFrameIsAlive | ( | IAX2Frame * | f | ) |

A simple test to report if the connection associated with this frame is still alive. This test is used when transmitting the frame. If the connection is gone, don't bother transmitting the frame. There are exceptins to this rule, such as when a hangup packet is sent (which is after the connections has died.

PBoolean IAX2EndPoint::ConnectionForFrameIsAlive | ( | IAX2Frame * | f | ) |

It is possible that a retransmitted frame has been in the transmit queue, and while sitting there that frames sending connection has died. Thus, prior to transmission, call tis method.

Returns
  True if a connection (which matches this Frame ) can be found.

void IAX2EndPoint::CopyLocalMediaFormats | ( | OpalMediaFormatList & | list | ) |

Copy to the supplied OpalMediaList the media formats we support

virtual IAX2Connection* IAX2EndPoint::CreateConnection | ( | OpalCall & | call,

|  | void * | userData,
|  | const PString & | remoteParty,
|  | const PString & | remotePartyName = `PString::Empty()`
| ) |  |

virtual

Create a connection for the IAX endpoint. The default implementation is to create a IAX2Connection.

Parameters

  token | Owner of connection
  userData | token used to identify connection
  remoteParty | User data for connection
  remotePartyName | Url to call or is calling. Name to call or is calling.

static PStringArray IAX2EndPoint::DissectRemoteParty | ( | const PString & | other | ) |

static

Given a remote party name of the format:

[proto:][alias@][transport$]address[/extension]

pull the string apart and get the components. The compoents are stored in a PStringList, indexed by the enum RemoteAddressFields

virtual OpalMediaFormatList IAX2EndPoint::GetMediaFormats | ( |  | ) | const

virtual

Get the data formats this endpoint is capable of operating. This provides a list of media data format names that may be used by an OpalMediaStream may be created by a connection from this endpoint.

Note that a specific connection may not actually support all of the media formats returned here, but should return no more.

The default behaviour is pure.

Implements OpalEndPoint.

PINDEX IAX2EndPoint::GetRegistrationsCount | ( |  | ) |

Get the number of accounts that are being registered

PINDEX IAX2EndPoint::GetSupportedCodecs | ( | OpalMediaFormatList & | list | ) |

Return the bitmask which specifies the possible codecs we support

virtual void IAX2EndPoint::IncomingEthernetFrame | ( | IAX2Frame * | frame | ) |

virtual

Handle a received IAX frame. This may be a mini frame or full frame

PBoolean IAX2EndPoint::Initialise | ( |  | ) |

Setup the Endpoint internval variables, which is called at program startup.

PBoolean IAX2EndPoint::InitialisedOK | ( |  | ) |

WORD IAX2EndPoint::ListenPortNumber | ( |  | ) |

inline

Report the port in use for IAX calls

virtual PSafePtr<OpalConnection> IAX2EndPoint::MakeConnection | ( | OpalCall & | call,
|  | const PString & | party,
|  | void * | userData = `NULL`,
|  | unsigned int | options = `0`,
|  | OpalConnection::StringOptions * | stringOptions = `NULL`
| ) |  |

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:

[iax2:]{username@][transport$]address[/extension][+context]

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 false is returned.

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

If false 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 connection

Implements OpalEndPoint.

virtual PBoolean IAX2EndPoint::NewIncomingConnection | ( | OpalTransport * | transport | ) |

virtual

Handle new incoming connection from listener.

The default behaviour does nothing.

Parameters

  transport | Transport connection came in on

Reimplemented from OpalEndPoint.

void IAX2EndPoint::NewIncomingConnection | ( | IAX2Frame * | f | ) |

Handle new incoming connection from listener.

A return value of true indicates that the transport object should be deleted by the caller. false indicates that something else (eg the connection) has taken over responsibility for deleting the transport.

Well, that is true of Opal. In iax2, we do all the work of creating a new connection etc. The transport arguement is ignore. In Iax2, this method is void, as no value is returned. Further, in iax2, we process the incoming frame.

Parameters

  f | Frame carrying the new request.

PINDEX IAX2EndPoint::NextSrcCallNumber | ( | IAX2Processor * | processor | ) |

Request a new source call number, one that is different to all other source call numbers for this program.

Returns
  P_MAX_INDEX if there is no available call number, or return a unique valid call number.

void IAX2EndPoint::OnEstablished | ( | OpalConnection & | con | ) |

virtual

A call back function whenever a connection is established. This indicates that a connection to an endpoint was established. This usually occurs after OnConnected() and indicates that the connection is both connected and has media flowing.

Reimplemented from OpalEndPoint.

virtual void IAX2EndPoint::OnRegistered | ( | const PString & | host,
|  | const PString & | userName,
|  | PBoolean | isFailure,
|  | RegisteredError | reason = `RegisteredFailureUnknown`
| ) |  |

virtual

This is a call back if an event related to registration occurs. This callback should return as soon as possible.

virtual void IAX2EndPoint::OnReleased | ( | OpalConnection & | connection | ) |

virtual

Called whenever a connection instance is finished being used to manage a call. We trap this callback to remove the connection from this endpoints token table. Once we are done the token table, we then call the generic OpalEndpoint::OnReleased method.

Parameters

  connection | Connection that was established

Reimplemented from OpalEndPoint.

virtual void IAX2EndPoint::OnUnregistered | ( | const PString & | host,
|  | const PString & | userName,
|  | PBoolean | isFailure,
|  | UnregisteredError | reason = `UnregisteredFailureUnknown`
| ) |  |

virtual

This is a call back if an event related to unregistration occurs. This callback should return as soon as possible. Generally even if a failure occurs when unregistering it should be ignored because it does not matter to much that it couldn't unregister.

PBoolean IAX2EndPoint::ProcessFrameInConnection | ( | IAX2Frame * | f,
|  | const PString & | token
| ) |  |

protected

For the supplied IAX2Frame, pass it to a connection in the connectionsActive structure. We are told the token of the connection that matches this particular frame.

Returns
  true - this is the normal and expected outcome.
  false - connection not found - say it died immediately before this method was called

PBoolean IAX2EndPoint::ProcessInConnectionTestAll | ( | IAX2Frame * | f | ) |

protected

Take the supplied frame, and compare it with all the existing connections. If any of the existing connections has a matching dest call number, then put this frame to that connection.

Update the token translation dictionary if the supplied frame has a valid connection token.

PBoolean IAX2EndPoint::ProcessInMatchingConnection | ( | IAX2Frame * | f | ) |

protected

For the supplied IAX2Frame, pass it to a connection in the connectionsActive structure. If no matching connection is found, return false;

If a matching connections is found, give the frame to the connection (for the connection to process) and return true;

void IAX2EndPoint::ProcessReceivedEthernetFrames | ( |  | ) |

Pull frames off the incoming list, and pass on to the relevant connection. If no matching connection found, delete the frame. Repeat the process until no frames are left.

void IAX2EndPoint::Register | ( | const PString & | host,
|  | const PString & | username,
|  | const PString & | password = `PString::Empty()`,
|  | PINDEX | requestedRefreshTime = `60`
| ) |  |

Register with a remote iax2 server. The host can either be a hostname or ip address. The password is optional as some servers may not require it to register. The requested refresh time is the time that the registration should be refreshed in seconds. The time must be more than 10 seconds.

void IAX2EndPoint::ReportStoredConnections | ( |  | ) |

Write the token of all connections in the connectionsActive structure to the trace file

void IAX2EndPoint::ReportTransmitterLists | ( | PString & | answer,
|  | bool | getFullReport = `false`
| ) |  |

Report on the frames in the current transmitter class, which are pending transmission

void IAX2EndPoint::SetLocalNumber | ( | PString | newValue | ) |

Set the local (on this host) number to some value

void IAX2EndPoint::SetLocalUserName | ( | PString | newValue | ) |

Set the username to some value

void IAX2EndPoint::SetPassword | ( | PString | newValue | ) |

Set the password to some value

void IAX2EndPoint::StartRinging | ( | PString | remoteCaller | ) |

We have an incoming call. Do we accept ?

void IAX2EndPoint::Unregister | ( | const PString & | host,
|  | const PString & | username
| ) |  |

Unregister from a registrar. This function is synchronous so it will block.

## Field Documentation

PMutex IAX2EndPoint::callNumbLock

protected

lock on access to call numbers variable

int IAX2EndPoint::callnumbs

protected

Number of active calls

PAtomicInteger IAX2EndPoint::callsEstablished

protected

Thread safe counter which keeps track of the calls created by this endpoint. This value is used when giving outgoing calls a unique ID

PTime IAX2EndPoint::callStartTime

protected

Time when a call was started

IAX2IncomingEthernetFrames IAX2EndPoint::incomingFrameHandler

protected

Thread which transfers frames from the Receiver to the appropriate connection. It momentarily locks the connection list, searches through, and then completes the trasnsfer. If need be, this thread will create a new conneciton (to cope with a new incoming call) and add the new connections to the internal list.

OpalMediaFormatList IAX2EndPoint::localMediaFormats

protected

Local copy of the media types we can handle

PString IAX2EndPoint::localNumber

protected

Number, as used by the computer on the host running this program

Referenced by GetLocalNumber().

unsigned short IAX2EndPoint::localPort

protected

The local port

PString IAX2EndPoint::localUserName

protected

Name of this user, which is used as the IeCallingNumber

Referenced by GetLocalUserName().

PReadWriteMutex IAX2EndPoint::mutexTokenTable

protected

Threading mutex on the variable tokenTable. We can now safely read/write to this table, with the minimum of interference between threads.

IAX2FrameList IAX2EndPoint::packetsReadFromEthernet

protected

List of iax2 packets which has been read from the ethernet, and is to be sent to the matching IAX2Connection

Referenced by EthernetFramesToBeProcessed().

PString IAX2EndPoint::password

protected

Password for this user, which is used when processing an authentication request

Referenced by GetPassword().

IAX2Receiver* IAX2EndPoint::receiver

Pointer to the receiver class, which is always valid

PArrayObjects IAX2EndPoint::regProcessors

protected

An array of register processors. These are created when another class calls register and deleted when another class calls unregister or class destructor is called. This collection must be protected by the regProcessorsMutex

PMutex IAX2EndPoint::regProcessorsMutex

protected

A mutex to protect the registerProcessors collection

PUDPSocket* IAX2EndPoint::sock

protected

The socket on which all data is sent/received.

IAX2SpecialProcessor* IAX2EndPoint::specialPacketHandler

PINDEX IAX2EndPoint::statusQueryCounter

protected

Counter to use for sending on status query frames

PMutex IAX2EndPoint::statusQueryMutex

protected

Mutex for the statusQueryCounter

PStringToString IAX2EndPoint::tokenTable

protected

tokenTable is a hack to allow IAX2 to fit in with one of the demands of the opal library.

Opal demands that at connection setup, we know the unique ID which this call will use.

Since the unique ID is remote ip adress + remote's Source Call number, this is unknown if we are initiating the call. Consequently, this table is needed, as it provides a translation between the initial (or psuedo) token and the token that is later adopted

IAX2Transmit* IAX2EndPoint::transmitter

Pointer to the transmitter class, which is always valid
