[Francisco Correia (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=252468#comment-252468 ] 

Francisco Correia commented on ASTERISK-29130:
----------------------------------------------

Steps to Reproduce

1) Call enters a Stasis application
2) Stasis application starts playing music on hold on the caller channel
3) Stasis application dials one of the dummy extensions with a 10 second timeout
4) Repeats dial until some extension answer
Asterisk crashes

{noformat}
exten => 9980,1,NoOp(Calling Tiburcio Saidi)
 same =>      n,Set(LOCAL_AGENT_ANSWER_PROBABILITY=80)
 same =>      n,Set(LOCAL_AGENT_NAME=Tiburcio Saidi)
 same =>      n,Goto(local-agent-diaplan,s,1)



; Dummy Agent Dial Plan
[local-agent-diaplan]
exten => s,1,NoOp()
 same =>      n,DumpChan()
 same =>      n,Ringing()
 same =>      n,GotoIf($[${RAND(1,100)} < ${LOCAL_AGENT_ANSWER_PROBABILITY}]?answer:ignore)
 same =>      n(answer),NoOp(${LOCAL_AGENT_NAME} will take the call in a moment)
 same =>      n,Wait(${RAND(10,25)})
 same =>      n,Answer()
 same =>      n,Set(TIMEOUT(absolute)=${RAND(60,350)})
 same =>      n(playloop),Playback(tt-monkeys)
 same =>      n,Goto(playloop)
 same =>      n(ignore),NoOp(${LOCAL_AGENT_NAME} is busy doing something else, who knows what)
 same =>      n,Wait(${RAND(10,60)})
 same =>      n,Hangup()
