             Summary: AMI returns wrong event parameteres
                 Key: ASTERISK-27153
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27153
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/ManagerInterface
    Affects Versions: 14.6.0, 13.17.0
         Environment: CentOS 6 64Bit
            Reporter: Antonis Psaras


We have detected that, in some rare cases, Newexten events contain wrong Application / AppData fields (i.e. Application / AppData do not correspond to what was actually executed, but rather display the values corresponding to the previous execution for that channel).

Our test involves originating a call to TestPhone1, transferring that call to another asterisk via IAX2, then transferring the initial channel to TestPhone2 (local) and then transferring the call to an AGI application.

The problematic Newexten events can be seen at lines 3162 and 5246 of the attached log file. The actual executions (with the correct app/appdata) can be seen at lines 3127 and 5199 respectively. You can see that the Newexten @5246 contains the app/appdata fields that should have been contained by the Newexten @3162 event.

The same behavior is exhibited in both asterisk versions 13 and 14 (latest builds). The problem does not appear in asterisk versions 11 and back.

The manager actions we executed (and which do not appear in the attached log file) are the following:
Step 1:

action: Originate
channel: Local/mboBCmtGYDJ5UWxcKxQSWDzQg2 at mb_all_calls
context: mb_all_calls
exten: mbsLGrALV2_n0eoXJHXMsMZKQ1
priority: 1
timeout: 20000
callerid:  <5432>
account: TestPhone1
actionid: mboBCmtGYDJ5UWxcKxQSWDzQg2
async: 1
variable:

Step 2:

action: Redirect
channel: SIP/TestPhone1-00000000
extrachannel: 
context: mb_all_calls
exten: TestPhone2
priority: 1
actionid: @000000C3

Step 3:

action: Redirect
channel: SIP/TestPhone1-00000000
extrachannel: 
context: mb_all_calls
exten: mbuadBCmtGYDJ5UWxcKxQSWDzQg
priority: 1
actionid: @0000011C


All the extensions you see in the log file were registered by our software at the beginning of the test. Their full definition is as follows:
