Manager:
* The CallerID fields across Manager events have now been made more
consistent. CallerID Number will be sent as CallerIDNum and CallerID
Name will be sent as CallerIDName wherever used.
* Manager has been upgraded to version 1.1 with a lot of changes.
Please check doc/manager_1_1.txt for information
* The IAXpeers command output has been changed to more closely resemble the
output of the SIPpeers command.

Changes to manager version 1.1:
-------------------------------
* SYNTAX CLEANUPS
-----------------
- Response: headers are now either
"Success" - Action OK, this message contains response
"Error" - Action failed, reason in Message: header
"Follows" - Action OK, response follows in following Events.
- Manager version changed to 1.1
* CHANGED EVENTS AND ACTIONS
----------------------------
- The Hold/Unhold events
- Both are now "Hold" events
For hold, there's a "Status: On" header, for unhold, status is off
- Modules chan_sip/chan_iax2
- The Ping Action
- Now use Response: success
- New header "Ping: pong" :-)
- The Events action
- Now use Response: Success
- The new status is reported as "Events: On" or "Events: Off"
- The JabberSend action
- The Response: header is now the first header in the response
- now sends "Response: Error" instead of "Failure"
- Newstate and Newchannel events
- these have changed headers
"State" -> ChannelStateDesc Text based channel state
-> ChannelState Numeric channel state
- The events does not send "<unknown>" for unknown caller IDs just an empty field
- Newchannel event
- Now includes "AccountCode"
- Newstate event
- Now has "CalleridNum" for numeric caller id, like Newchannel
- The event does not send "<unknown>" for unknown caller IDs just an empty field
- Dial event
- Event Dial has new headers, to comply with other events
- Source -> Channel Channel name (caller)
- SrcUniqueID -> UniqueID Uniqueid
(new) -> Dialstring Dialstring in app data
- Link and Unlink events
- The "Link" and "Unlink" bridge events in channel.c are now renamed to "Bridge"
- The link state is in the bridgestate: header as "Link" or "Unlink"
- For channel.c bridges, "Bridgetype: core" is added. This opens up for
bridge events in rtp.c
- The RTP channel also reports Bridge: events with bridgetypes
- rtp-native RTP native bridge
- rtp-direct RTP peer-2-peer bridge (NAT support only)
- rtp-remote Remote (re-invite) bridge. (Not reported yet)
- The "Rename" manager event has a renamed header, to use the same
terminology for the current channel as other events
- Oldname -> Channel
- The "NewCallerID" manager event has a renamed header
- CallerID -> CallerIDnum
- The event does not send "<unknown>" for unknown caller IDs just an empty field
- Reload event
- The "Reload" event sent at manager reload now has a new header and is now implemented
in more modules than manager to alert a reload. For channels, there's a CHANNELRELOAD
event to use.
(new) -> Module: manager | CDR | DNSmgr | RTP | ENUM
(new) -> Status: enabled | disabled
- To support reload events from other modules too
- cdr module added
- Status action replies (Event: Status)
Header changes
- link -> BridgedChannel
- Account -> AccountCode
- (new) -> BridgedUniqueid
- StatusComplete Event
New header
- (new) -> Items Number of channels reported
- The ExtensionStatus manager command now has a "StatusDesc" field with text description of the state
- The Registry and Peerstatus events in chan_sip and chan_iax now use "ChannelType" instead of "ChannelDriver"
- The Response to Action: IAXpeers now have a Response: Success header
- The MeetmeJoin now has caller ID name and Caller ID number fields (like MeetMeLeave)
- Action ZapShowChannels
Header changes
- Channel: -> ZapChannel
For active channels, the Channel: and Uniqueid: headers are added
You can now add a "ZapChannel: " argument to zapshowchannels actions
to only get information about one channel.
- Event ZapShowChannelsComplete
New header
- (new) -> Items: Reports number of channels reported
* NEW ACTIONS
-------------
- Action: ModuleLoad
Modules: loader.c
Purpose:
To be able to unload, reload and unload modules from AMI.
Variables:
ActionID: <id> Action ID for this transaction. Will be returned.
Module: <name> Asterisk module name (including .so extension)
or subsystem identifier:
cdr, enum, dnsmgr, extconfig, manager, rtp, http
LoadType: load | unload | reload
The operation to be done on module
If no module is specified for a reload loadtype, all modules are reloaded
- Action: ModuleCheck
Modules: loader.c
Purpose:
To check version of a module - if it's loaded
Variables:
ActionID: <id> Action ID for this transaction. Will be returned.
Module: <name> Asterisk module name (not including extension)
Returns:
If module is loaded, returns version number of the module
Note: This will have to change. I don't like sending Response: failure
on both command not found (trying this command in earlier versions of
Asterisk) and module not found.
Also, check if other manager actions behave that way.
* NEW EVENTS
------------
- Event: Transfer
Modules: res_features, chan_sip
Purpose:
Inform about call transfer, linking transferer with transfer target
You should be able to trace the call flow with this missing piece
of information. If it works out well, the "Transfer" event should
be followed by a "Bridge" event
The transfermethod: header informs if this is a pbx core transfer
or something done on channel driver level. For SIP, check the example:
Example:
Event: Transfer
Privilege: call,all
TransferMethod: SIP
TransferType: Blind
Channel: SIP/device1-01849800
SIP-Callid: 091386f505842c87016c4d93195ec67d@127.0.0.1
TargetChannel: SIP/device2-01841200
TransferExten: 100
TransferContext: default
- Event: ChannelUpdate
Modules: chan_sip.c, chan_iax2.c
Purpose:
Updates channel information with ID of PVT in channel driver, to
be able to link events on channel driver level.
* Integrated in SVN trunk as of May 4th, 2007
Example:
Event: ChannelUpdate
Privilege: system,all
Uniqueid: 1177271625.27
Channel: SIP/olle-01843c00
Channeltype: SIP
SIPcallid: NTQzYWFiOWM4NmE0MWRkZjExMzU2YzQ3OWQwNzg3ZmI.
SIPfullcontact: sip:olle@127.0.0.1:49054
- Action: CoreSettings
Modules: manager.c
Purpose: To report core settings, like AMI and Asterisk version,
maxcalls and maxload settings.
* Integrated in SVN trunk as of May 4th, 2007
Example:
Response: Success
ActionID: 1681692777
AMIversion: 1.1
AsteriskVersion: SVN-oej-moremanager-r61756M
SystemName: EDVINA-node-a
CoreMaxCalls: 120
CoreMaxLoadAvg: 0.000000
CoreRunUser: edvina
CoreRunGroup: edvina
- Action: CoreStatus
Modules: manager.c
Purpose: To report current PBX core status flags, like
number of concurrent calls, startup and reload time.
* Integrated in SVN trunk as of May 4th, 2007
Example:
Response: Success
ActionID: 1649760492
CoreStartupTime: 22:35:17
CoreReloadTime: 22:35:17
CoreCurrentCalls: 20
- Event: NewAccountCode
Modules: cdr.c
Purpose: To report a change in account code for a live channel
Example:
Event: NewAccountCode
Privilege: call,all
Channel: SIP/olle-01844600
Uniqueid: 1177530895.2
AccountCode: Stinas account 1234848484
OldAccountCode: OllesAccount 12345
- Event: ModuleLoadReport
Modules: loader.c
Purpose: To report that module loading is complete. Some aggressive
clients connect very quickly to AMI and needs to know when
all manager events embedded in modules are loaded
Also, if this does not happen, something is seriously wrong.
This could happen to chan_sip and other modules using DNS.
Example:
Event: ModuleLoad
ModuleLoadStatus: Done
ModuleSelection: All
ModuleCount: 24
