This class is the central manager for OPAL. The OpalManager embodies the root of the tree of objects that constitute an OPAL system. It contains all of the endpoints that make up the system. Other entities such as media streams etc are in turn contained in these objects. It is expected that an application would only ever have one instance of this class, and also descend from it to override call back functions.
The manager is the eventual destination for call back indications from various other objects. It is possible, for instance, to get an indication of a completed call by creating a descendant of the OpalCall and overriding the OnClearedCall() virtual. However, this could quite unwieldy for all of the possible classes, so the default behaviour is to call the equivalent function on the OpalManager. This allows most applications to only have to create a descendant of the OpalManager and override virtual functions there to get all the indications it needs.
OpalManager::OpalManager | ( | ) |
Create a new manager.
OpalManager::~OpalManager | ( | ) |
Destroy the manager. This will clear all calls, then delete all endpoints still attached to the manager.
|
virtual |
Add a presentity. If the presentity is already present, a new one is not added, and the existing instance is returned.
Returns a Read/Write locked pointer to presentity.
presentity | Presentity URI |
Referenced by FindCallWithLock().
|
virtual |
Add a route entry to the route table.
The specification string is of the form:
pattern '=' destination
where:
pattern regular expression used to select route destination destination for the call
The "pattern" string regex is compared against routing strings that are built as follows:
a_party '\\t' b_party
where:
a_party name associated with a local connection i.e. "pots:vpb:1/2" or "h323:myname@myhost.com". b_party destination specified by the call, which may be a full URI or a simple digit string
Note that all "pattern" strings have an implied '^' at the beginning and a '$' at the end. This forces the "pattern" to match the entire source string. For convenience, the sub-expression ".*\\t" is inserted immediately after any ':' character if no '\t' is present.
Route entries are stored and searched in the route table in the order they are added.
The "destination" string is determines the endpoint used for the outbound leg of the route, when a match to the "pattern" is found. It can be a literal string, or can be constructed using various meta-strings that correspond to parts of the source. See below for a list of the available meta-strings
A "destination" starting with the string 'label:' causes the router to restart searching from the beginning of the route table using the new string as the "a_party". Thus, a route table with the folllwing entries:
"label:speeddial=h323:10.0.1.1" "pots:26=label:speeddial"
will produce the same result as the single entry "pots:26=h323:10.0.1.1".
If the "destination" parameter is of the form @filename, then the file is read with each line consisting of a pattern=destination route specification.
"destination" strings without an equal sign or beginning with '#' are ignored.
1) A local H.323 endpoint with with name of "myname@myhost.com" that receives a call with a destination h323Id of "boris" would generate:
"h323:myname@myhost.com\\tboris"
2) A local SIP endpoint with with name of "fred@nurk.com" that receives a call with a destination of "sip:fred@nurk.com" would generate:
"sip:fred@nurk.com\\tsip:fred@nurk.com"
3) Using line 0 of a PhoneJACK handset with a serial # of 01AB3F4 to dial the digits 2, 6 and # would generate:
"pots:Quicknet:01AB3F4:0\\t26"
The available meta-strings are:
<da> Replaced by the "b_party" string. For example "pc:.*\\t.* = sip:<da>" directs calls to the SIP protocol. In this case there is a special condition where if the original destination had a valid protocol, eg h323:fred.com, then the entire string is replaced not just the <da> part.
<db> Same as <da>, but without the special condtion.
<du> Copy the "user" part of the "b_party" string. This is essentially the component after the : and before the '@', or the whole "b_party" string if these are not present.
<!du> The rest of the "b_party" string after the <du> section. The protocol is still omitted. This is usually the '@' and onward. Note if there is already an '@' in the destination before the <!du> and what is abour to replace it also has an '@' then everything between the @ and the <!du> (inclusive) is deleted, then the substitution is made so a legal URL can result.
<dn> Copy all valid consecutive E.164 digits from the "b_party" so pots:0061298765@vpb:1/2 becomes sip:00612 9876 5@car rier .com
<dnX> As above but skip X digits, eg <dn2> skips 2 digits, so pots:00612198765 becomes sip:61298 765@ carri er.c om
<!dn> The rest of the "b_party" after the <dn> or <dnX> sections.
<dn2ip> Translate digits separated by '*' characters to an IP address. e.g. 10*0*1*1 becomes 10.0.1.1, also 1234*10*0*1*1 becomes 1234@10.0.1.1 and 1234*10*0*1*1*1722 becomes 1234@10.0.1.1:1722.
Returns true if an entry was added.

Adjust media formats available on a connection. This is called by a connection after it has called OpalCall::GetMediaFormats() to get all media formats that it can use so that an application may remove or reorder the media formats before they are used to open media streams.
The default behaviour uses the mediaFormatOrder and mediaFormatMask member variables to adjust the mediaFormats list.

Route the source address to a destination using the route table. The source parameter may be something like pots:vpb:1/2 or sip:fred@nurk.com.
The destination parameter is a partial URL, it does not include the protocol, but may be of the form user@host, or simply digits.
source | Source address, including endpoint protocol |
destination | Destination address read from source protocol |

Determine if the RTP session needs to accommodate a NAT router. For endpoints that do not use STUN or something similar to set up all the correct protocol embeddded addresses correctly when a NAT router is between the endpoints, it is possible to still accommodate the call, with some restrictions. This function determines if the RTP can proceed with special NAT allowances.
The special allowance is that the RTP code will ignore whatever the remote indicates in the protocol for the address to send RTP data and wait for the first packet to arrive from the remote and will then proceed to send all RTP data back to that address AND port.
The default behaviour checks the values of the physical link (localAddr/peerAddr) against the signaling address the remote indicated in the protocol, eg H.323 SETUP sourceCallSignalAddress or SIP "To" or "Contact" fields, and makes a guess that the remote is behind a NAT router.

Set up a connection to a remote party. An appropriate protocol (endpoint) is determined from the party parameter. That endpoint is then called to create a connection and that connection is attached to the call provided.
If the endpoint is already occupied in a call then the endpoints list is further searched for additional endpoints that support the protocol. For example multiple pstn endpoints may be present for multiple LID's.
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 default for the proto is the name of the protocol for the first endpoint attached to the manager. Other fields default to values on an endpoint basis.
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 associated 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.

Call back for remote party being alerted on outgoing call. This function is called after the connection is informed that the remote endpoint is "ringing". This function is generally called some time after the MakeConnection() function was called.
If false is returned the connection is aborted.
If an application overrides this function, it should generally call the ancestor version for correct operation. An application would typically only intercept this function if it wishes to do some form of logging. For this you can obtain the name of the caller by using the function OpalConnection::GetRemotePartyName().

Call back for answering an incoming call. This function is called after the connection has been acknowledged but before the connection is established
This gives the application time to wait for some event before signalling to the endpoint that the connection is to proceed. For example the user pressing an "Answer call" button.
If AnswerCallDenied is returned the connection is aborted and the connetion specific end call PDU is sent. If AnswerCallNow is returned then the connection proceeding, Finally if AnswerCallPending is returned then the protocol negotiations are paused until the AnsweringCall() function is called.
The default behaviour simply returns AnswerNow.

A call back function whenever a call is cleared. A call is cleared whenever there is no longer any connections attached to it. This function is called just before the call is deleted. However, it may be used to display information on the call after completion, eg the call parties and duration.
Note that there is not a one to one relationship with the OnEstablishedCall() function. This function may be called without that function being called. For example if MakeConnection() was used but the call never completed.

Call back for answering an incoming call. This function is used for an application to control the answering of incoming calls.
If true is returned then the connection continues. If false then the connection is aborted.
Note this function should not block for any length of time. If the decision to answer the call may take some time eg waiting for a user to pick up the phone, then AnswerCallPending or AnswerCallDeferred should be returned.
If an application overrides this function, it should generally call the ancestor version to complete calls. Unless the application completely takes over that responsibility. Generally, an application would only intercept this function if it wishes to do some form of logging. For this you can obtain the name of the caller by using the function OpalConnection::GetRemotePartyName().
The default behaviour is to call OnRouteConnection to determine a B party for the connection.
If the call associated with the incoming call already had two parties and this connection is a third party for a conference call then AnswerCallNow is returned as a B party is not required.

Indicate is a local RTP connection. This is called when a new media stream has been created and it has been detected that media will be flowing between two RTP sessions within the same process. An application could take advantage of this by optimising the transfer in some way, rather than the full media path of codecs and sockets which might not be necessary.
Note this is the complement to SetMediaPassThrough() as this function stops RTP data from being sent/received, while SetMediaPassThrough() transfers RTP data between the two endpoints.
The default behaviour returns false.

Call back when opening a media stream. This function is called when a connection has created a new media stream according to the logic of its underlying protocol.
The usual requirement is that media streams are created on all other connections participating in the call and all of the media streams are attached to an instance of an OpalMediaPatch object that will read from one of the media streams passing data to the other media streams.
The default behaviour achieves the above using the FindMatchingCodecs() to determine what (if any) software codecs are required, the OpalConnection::CreateMediaStream() function to open streams and the CreateMediaPatch() function to create a patch for all of the streams and codecs just produced.

Call back for remote party is now responsible for completing the call. This function is called when the remote system has been contacted and it has accepted responsibility for completing, or failing, the call. This is distinct from OnAlerting() in that it is not known at this time if anything is ringing. This indication may be used to distinguish between "transport" level error, in which case another host may be tried, and that finalising the call has moved "upstream" and the local system has no more to do but await a result.
If an application overrides this function, it should generally call the ancestor version for correct operation.

A call back function to monitor the progress of a transfer. When a transfer operation is initiated, the Transfer() function will generally return immediately and the transfer may take some time. This call back can give an indication to the application of the progress of the transfer. the transfer.
For example in SIP, the OpalCall::Transfer() function will have sent a REFER request to the remote party. The remote party sends us NOTIFY requests about the progress of the REFER request.
An application can now make a decision during the transfer operation to short circuit the sequence, or let it continue. It can also determine if the transfer did not go through, and it should "take back" the call. Note no action is required to "take back" the call other than indicate to the user that they are back on.
A return value of false will immediately disconnect the current call.
The exact format of the info
parameter is dependent on the protocol being used. As a minimum, it will always have a values info["result"] and info["party"].
The info["party"] indicates the part the connection
is playing in the transfer. This will be: "A" party being transferred "B" party initiating the transfer of "A" "C" party "A" is being transferred to
The info["result"] will be at least one of the following: "success" Transfer completed successfully (party A or B) "incoming" New call was from a transfer (party C) "started" Transfer operation has started (party A) "progress" Transfer is in progress (party B) "blind" Transfer is blind, no further notification (party B) "error" Transfer could not begin (party B) "failed" Transfer started but did not complete (party A or B)
For SIP, there may be an additional info["state"] containing the NOTIFY subscription state, an info["code"] entry containing the 3 digit code returned in the NOTIFY body and info["Referred-By"] indicating the URI of party B. Other fields may also be present.
The default behaviour returns false if info["result"] == "success".

Set pass though mode for media.
Bypass the internal media handling, passing RTP data directly from one call/connection to another.
This can be useful for back to back calls that happen to be the same media format and you wish to avoid double decoding and encoding of media. Note this scenario is not the same as two OpalConnections within the same OpalCall, but two completely independent OpalCall where one connection is to be bypassed. For example, two OpalCall instances might have two SIPConnection instances and two OpalMixerConnection instances connected via a single OpalMixerNode. Now while there are ONLY two calls in the node, it is a waste to decode the audio, add to mixer and re-encode it again. In practice this is identical to just bypassing the mixer node completely, until a third party is added, then we need to switch back to normal (non-pass-through) operation.
Note this is the complement to OnLocalRTP() as this function transfers RTP data directly between the two endpoints, while OnLocalRTP() stops the RTP data from being sent/received.
