--- Functionality changes from Asterisk 11 to Asterisk 12 --------------------
------------------------------------------------------------------------------
+Overview
+------------------
+
+Asterisk 12 is a standard release of the Asterisk project. As such, the
+focus of development for this release was on core architectural changes and
+major new features. This includes:
+ * A more flexible bridging core based on the Bridging API
+ * A new internal message bus, Stasis
+ * Major standardization and consistency improvements to AMI
+ * Addition of the Asterisk RESTful Interface (ARI)
+ * A new SIP channel driver, chan_pjsip
+In addition, as the vast majority of bridging in Asterisk was migrated to the
+Bridging API used by ConfBridge, major changes were made to most of the
+interfaces in Asterisk. This includes not only AMI, but also CDRs and CEL.
+
+Specifications have been written for the affected interfaces. These
+specifications are available on the Asterisk wiki:
+ * AMI - https://wiki.asterisk.org/wiki/x/dAFRAQ
+ * CEL - https://wiki.asterisk.org/wiki/x/4ICLAQ
+ * CDRs - https://wiki.asterisk.org/wiki/x/pwpRAQ
+
+It is *highly* recommended that anyone migrating to Asterisk 12 read the
+information regarding its release both in this file and in the accompanying
+UPGRADE.txt file. More detailed information on the major changes can be found
+on the Asterisk wiki at https://wiki.asterisk.org/wiki/x/0YCLAQ.
+
+
+Build System
+------------------
+ * Added build option DISABLE_INLINE. This option can be used to work around a
+ bug in gcc. For more information, see
+ http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47816
+
+ * Removed the CHANNEL_TRACE development mode build option. Certain aspects of
+ the CHANNEL_TRACE build option were incompatible with the new bridging
+ architecture.
+
+ * Asterisk now optionally uses libxslt to improve XML documentation generation
+ and maintainability. If libxslt is not available on the system, some XML
+ documentation will be incomplete.
+
+ * Asterisk now depends on libjansson. If a package of libjansson is not
+ available on your distro, please see http://www.digip.org/jansson/.
+
+ * Asterisk now depends on libuuid and, optionally, uriparser. It is
+ recommended that you install uriparser, even if it is optional.
+
+ * The new SIP stack and channel driver uses a particular version of PJSIP.
+ Please see https://wiki.asterisk.org/wiki/x/J4GLAQ for more information on
+ configuring and installing PJSIP for usage with Asterisk.
+
+
Applications
------------------
AgentLogin
------------------
- * The application no longer does agent authentication. The dialplan needs to
- perform this function before running AgentLogin. If the agent is already
- logged in, dialplan will continue with the AGENT_STATUS channel variable
- set to ALREADY_LOGGED_IN.
+ * Along with AgentRequest, this application has been modified to be a
+ replacement for chan_agent. The act of a channel calling the AgentLogin
+ application places the channel into a pool of agents that can be
+ requested by the AgentRequest application. Note that this application, as
+ well as all other agent related functionality, is now provided by the
+ app_agent_pool module. See chan_agent and AgentRequest for more information.
+
+ * This application no longer performs agent authentication. If authentication
+ is desired, the dialplan needs to perform this function using the
+ Authenticate or VMAuthenticate application or through an AGI script before
+ running AgentLogin.
+
+ * If this application is called and the agent is already logged in, the
+ dialplan will continue exection with the AGENT_STATUS channel variable set
+ to ALREADY_LOGGED_IN.
+
+ * The agents.conf schema has changed. Rather than specifying agents on a
+ single line in comma delineated fashion, each agent is defined in a separate
+ context. This allows agents to use the power of context templates in their
+ definition.
+
+ * A number of parameters from agents.conf have been removed. This includes
+ maxloginretries, autologoffunavail, updatecdr, goodbye, group, recordformat,
+ urlprefix, and savecallsin. These options were obsoleted by the move from
+ a channel driver model to the bridging/application model provided by
+ app_agent_pool.
+
+AgentRequest
+------------------
+ * A new application, this will request a logged in agent from the pool and
+ bridge the requested channel with the channel calling this application.
+ Logged in agents are those channels that called the AgentLogin application.
+ If an agent cannot be requested from the pool, the AGENT_STATUS dialplan
+ application will be set with an appropriate error value.
AgentMonitorOutgoing

- * Application removed. It was a holdover from when AgentCallbackLogin was
- removed.
+ * This application has been removed. It was a holdover from when

+
+AlarmReceiver
+------------------
+ * Added support for additional Ademco DTMF signalling formats, including
+ Express 4+1, Express 4+2, High Speed and Super Fast.
+
+ * Added channel variable ALARMRECEIVER_CALL_LIMIT. This sets the maximum
+ call time, in milliseconds, to run the application.
+
+ * Added channel variable ALARMRECEIVER_RETRIES_LIMIT. This sets the
+ maximum number of times to retry the call.
+
+ * Added a new configuration option answait. If set, the AlarmReceiver
+ application will wait the number of milliseconds specified by answait
+ after the channel has answered. Valid values range between 500
+ milliseconds and 10000 milliseconds.
+
+ * Added configuration option no_group_meta. If enabled, grouping of metadata
+ information in the AlarmReceiver log file will be skipped.
+
+BridgeWait
+------------------
+ * A new application in Asterisk, this will place the calling channel
+ into a holding bridge, optionally entertaining them with some form of
+ media. Channels participating in a holding bridge do not interact with
+ other channels in the same holding bridge. Optionally, however, a channel
+ may join as an announcer. Any media passed from an announcer channel is
+ played to all channels in the holding bridge. Channels leave a holding
+ bridge either when an optional timer expires, or via the ChannelRedirect
+ application or AMI Redirect action.
ConfBridge
------------------
* All participants in a bridge can now be kicked out of a conference room
by specifying the channel parameter as 'all' in the ConfBridge kick CLI
- command, i.e., "confbridge kick <conference> all"
+ command, i.e., 'confbridge kick <conference> all'
+
+ * CLI output for the 'confbridge list' command has been improved. When
+ displaying information about a particular bridge, flags will now be shown
+ for the participating users indicating properties of that user.
+
+ * The ConfbridgeList event now contains the following fields: WaitMarked,
+ EndMarked, and Waiting. This displays additional properties about the
+ user's profile, as well as whether or not the user is waiting for a
+ Marked user to enter the conference.
+
+ * Added a new option for conference recording, record_file_append. If enabled,
+ when the recording is stopped and then re-started, the existing recording
+ will be used and appended to.
+
+ControlPlayback
+------------------
+ * The channel variable CPLAYBACKSTATUS may now return the value
+ 'REMOTESTOPPED'. This occurs when playback is stopped by a remote interface,
+ such as AMI. See the AMI action ControlPlayback for more information.
+
+Directory
+------------------
+ * Added the 'a' option, which allows the caller to enter in an additional
+ alias for the user in the directory. This option must be used in conjunction
+ with the 'f', 'l', or 'b' options. Note that the alias for a user can be
+ specified in voicemail.conf.
+
+DumpChan
+------------------
+ * The output of DumpChan no longer includes the DirectBridge or IndirectBridge
+ fields. Instead, if a channel is in a bridge, it includes a BridgeID field
+ containing the unique ID of the bridge that the channel happens to be in.

+MixMonitor
+------------------
+ * The 'b' option now includes conferences as well as sounds played to the
+ participants.
+
+ * The AUDIOHOOK_INHERIT function is no longer needed to keep a MixMonitor
+ running during a transfer. If a MixMonitor is started on a channel,
+ the MixMonitor will continue to record the audio passing through the
+ channel even in the presence of transfers.
NoCDR
------------------
* The NoCDR application is deprecated. Please use the CDR_PROP function to
disable CDRs.
+
* While the NoCDR application will prevent CDRs for a channel from being
propagated to registered CDR backends, it will not prevent that data from
being collected. Hence, a subsequent call to ResetCDR or the CDR_PROP
function that enables CDRs on a channel will restore those records that have
not yet been finalized.
+ParkAndAnnounce
+-------------------
+ * The app_parkandannounce module has been removed. The application
+ ParkAndAnnounce is now provided by the res_parking module. See the
+ res_parking changes for more information.
+
Queue
-------------------
- * Add queue available hint. exten => 8501,hint,Queue:markq_avail
- Note: the suffix '_avail' after the queuename.
- Reports 'InUse' for no logged in agents or no free agents.
- Reports 'Idle' when an agent is free.
+ * Added queue available hint. The hint can be added to the dialplan using the
+ following syntax: exten,hint,Queue:{queue_name}_avail
+ For example, if the name of the queue is 'markq':
+ exten => 8501,hint,Queue:markq_avail
+ This will report 'InUse' if there are no logged in agents or no free agents.
+ It will report 'Idle' when an agent is free.
+
+ * Queues now support a hint for member paused state. The hint uses the form
+ 'Queue:{queue_name}_pause_{member_name}', where {queue_name} and {member_name}
+ are the name of the queue and the name of the member to subscribe to,
+ respectively. For example: exten => 8501,hint,Queue:sales_pause_mark.
+ Members will show as In Use when paused.
* The configuration options eventwhencalled and eventmemberstatus have been
removed. As a result, the AMI events QueueMemberStatus, AgentCalled,
AgentConnect, AgentComplete, AgentDump, and AgentRingNoAnswer will always be
sent. The "Variable" fields will also no longer exist on the Agent* events.

+
+ * Added the 'queue_log_realtime_use_gmt' option to have timestamps in GMT
+ for realtime queue log entries.
ResetCDR
------------------
* The 'e' option has been deprecated. Use the CDR_PROP function to re-enable
CDRs when they were previously disabled on a channel.
+
* The 'w' and 'a' options have been removed. Dispatching CDRs to registered
backends occurs on an as-needed basis in order to preserve linkedid
propagation and other needed behavior.
+SayAlphaCase
+------------------
+ * A new application, this is similar to SayAlpha except that it supports
+ case sensitive playback of the specified characters. For example,

Core
------------------
- * Redirecting reasons can now be set to arbitrary strings. This means
- that the REDIRECTING dialplan function can be used to set the redirecting
- reason to any string. It also allows for custom strings to be read as the
- redirecting reason from SIP Diversion headers.
-
- * For DTMF blind and attended transfers, the channel variable TRANSFER_CONTEXT
- must be on the channel initiating the transfer to have any effect.
+ * Masquerades as an operation inside Asterisk have been effectively hidden
+ by the migration to the Bridging API. As such, many 'quirks' of Asterisk
+ no longer occur. This includes renaming of channels, "<ZOMBIE>" channels,
+ dropping of frame/audio hooks, and other internal implementation details
+ that users had to deal with. This fundamental change has large implications
+ throughout the changes documented for this version. For more information
+ about the new core architecture of Asterisk, please see the Asterisk wiki.

+CLI
+-------------------
+ * When compiled with '--enable-dev-mode', the astobj2 library will now add
+ several CLI commands that allow for inspection of ao2 containers that
+ register themselves with astobj2. The CLI commands are 'astobj2 container
+ dump', 'astobj2 container stats', and 'astobj2 container check'.
+
+ * Added specific CLI commands for bridge inspection. This includes 'bridge
+ show all', which lists all bridges in the system, and 'bridge show {id}',
+ which provides specific information about a bridge.
+
+ * Added CLI command 'bridge destroy'. This will destroy the specified bridge,
+ ejecting the channels currently in the bridge. If the channels cannot
+ continue in the dialplan or application that put them in the bridge, they
+ will be hung up.
+
+ * Added command 'bridge kick'. This will eject a single channel from a bridge.
+
+ * Added commands to inspect and manipulate the registered bridge technologies.
+ This include 'bridge technology show', which lists the registered bridge
+ technologies, as well as 'bridge technology {suspend|unsuspend} {tech}',
+ which controls whether or not a registered bridge technology can be used
+ during smart bridge operations. If a technology is suspended, it will not
+ be used when a bridge technology is picked for channels; when unsuspended,
+ it can be used again.
+
+ * The command 'config show help {module} {type} {option}' will show
+ configuration documentation for modules with XML configuration
+ documentation. When {module}, {type}, and {option} are omitted, a listing
+ of all modules with registered documentation is displayed. When {module}
+ is specified, a listing of all configuration types for that module is

+ detailed information about a sound, respectively.
+
+ * 'xmldoc dump' has been added. This CLI command will dump the XML
+ documentation DOM as a string to the specified file. The Asterisk core
+ will populate certain XML elements pulled from the source files with
