Mark Michelson	57c8eea6fe	Change cc_ref and cc_unref from macros to inline functions. ... The hope is that Solaris won't be as whiny after this change. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@259357 65c4cc65-6c06-0410-ace0-fbb531ad65f3	15 years ago
Mark Michelson	69c252c290	Fix issue where recall would not happen when it should. ... Specifically, the situation would happen when multiple callers would request CC for a single generically-monitored device. If the monitored device became available but the caller did not answer the recall, then there was nothing that would poke the CC core to let it know that it should attempt to recall someone else instead. After careful consideration, I came to the conclusion that the only area of Asterisk that needed to be touched was the generic CC monitor. All other types of CC would require something outside of Asterisk to invoke a recall for a separate device. This was accomplished by changing the generic monitor destructor to poke other generic monitor instances if the device is currently available and the specific instance was currently not suspended. In order to not accidentally trigger recalls at bad times, the fit_for_recall flag was also added to the generic_monitor_instance_list struct. This gets set as soon as a monitored device becomes available. It gets cleared if a CCNR request triggers the creation of a new generic monitor instance. By doing this, we don't accidentally try to recall a device when the monitored device was being monitored for CCNR and never actually became available for recall in the first place. This error was discovered by Steve Pitts during in-house testing at Digium. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@256985 65c4cc65-6c06-0410-ace0-fbb531ad65f3	15 years ago

Mark Michelson	e24661fd18	Merge Call completion support into trunk. ... From Reviewboard: CCSS stands for Call Completion Supplementary Services. An admittedly out-of-date overview of the architecture can be found in the file doc/CCSS_architecture.pdf in the CCSS branch. Off the top of my head, the big differences between what is implemented and what is in the document are as follows: 1. We did not end up modifying the Hangup application at all. 2. The document states that a single call completion monitor may be used across multiple calls to the same device. This proved to not be such a good idea when implementing protocol-specific monitors, and so we ended up using one monitor per-device per-call. 3. There are some configuration options which were conceived after the document was written. These are documented in the ccss.conf.sample that is on this review request. For some basic understanding of terminology used throughout this code, see the ccss.tex document that is on this review. This implements CCBS and CCNR in several flavors. First up is a "generic" implementation, which can work over any channel technology provided that the channel technology can accurately report device state. Call completion is requested using the dialplan application CallCompletionRequest and can be canceled using CallCompletionCancel. Device state subscriptions are used in order to monitor the state of called parties. Next, there is a SIP-specific implementation of call completion. This method uses the methods outlined in draft-ietf-bliss-call-completion-06 to implement call completion using SIP signaling. There are a few things to note here: * The agent/monitor terminology used throughout Asterisk sometimes is the reverse of what is defined in the referenced draft. * Implementation of the draft required support for SIP PUBLISH. I attempted to write this in a generic-enough fashion such that if someone were to want to write PUBLISH support for other event packages, such as dialog-state or presence, most of the effort would be in writing callbacks specific to the event package. * A subportion of supporting PUBLISH reception was that we had to implement a PIDF parser. The PIDF support added is a bit minimal. I first wrote a validation routine to ensure that the PIDF document is formatted properly. The rest of the PIDF reading is done in-line in the call-completion-specific PUBLISH-handling code. In other words, while there is PIDF support here, it is not in any state where it could easily be applied to other event packages as is. Finally, there are a variety of ISDN-related call completion protocols supported. These were written by Richard Mudgett, and as such I can't really say much about their implementation. There are notes in the CHANGES file that indicate the ISDN protocols over which call completion is supported.
