             Summary: Open parentheses or bracket in body breaks UserEvent app
                 Key: ASTERISK-29911
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29911
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_userevent
    Affects Versions: 18.9.0
         Environment: Debian 11
            Reporter: Niksa Baldun


I send an UserEvent from dialplan, which has a dialed number in the body. One user accidentally tried to dial a "number" which contained an unclosed parentheses, and everything fell apart. For example:

UserEvent(someevent,num="123(45",name="some name")

Instead of expected lines:

{code}
num: 123(45
name: some name
{code}

AMI event contains just one line:

{code}
num: 123(45,name=some name
{code}

It seems the problem is that UserEvent implementation uses AST_STANDARD_APP_ARGS function for parsing, but the body contains arbitrary key-value pairs, not standard args.
