    <p>Hello,</p>
    <p>are you using accounting to generate CDRs with dialog module
      (records in acc_cdrs table)? Or only for getting the event records
      in the acc table?</p>
    <p>Cheers,<br>
      Daniel<br>

                  <br>
                  as I am not a user of dialog variables, I am turning
                  to community to ask<br>
                  for help testing the current master branch with
                  configurations that make<br>
                  use of dialog variables and acc dialog-based cdr
                  generation.<br>
                  <br>
                  With a few reports of issues related to dialog modules
                  and unexpected<br>
                  crashes, I looked over the code and noticed that the
                  access of the value<br>
                  for dialog variables was not protected, making them
                  vulnerable of<br>
                  invalid memory access in case of the variable was
                  updated by another<br>
                  process or dialog was terminated.<br>
                  <br>
                  I introduced a couple of new functions to try to cover
                  different use<br>
                  cases of getting the dlg variable values, dialog
                  management code was not<br>
                  affected, but given that these commits need to be
                  backported to stable<br>
                  branch (5.6), I want to get proper feedback from
                  community that things<br>
                  work fine.<br>
                  <br>
                  A previous attempt of a simpler fix was not enough,
                  having side effects<br>
                  to acc module for dialog-based cdr generation, because
                  it was keeping<br>
                  referenced to many dlg variables at the same time.<br>
                  <br>
                  In short, it would be appreciated any feedback on
                  testing dialog and acc<br>
                  with dialog-based cdr generation using git master
                  branch.<br>
