The accounting module seems to inserts random data into reason header fields, see attached screenshot. This was observed after an upgrade to Kamailio 5.5.4 from an 5.4.9. I did a quick review of the changes between both branches, and the commit c5f6ff37f61f99e0 seems to be touching this functionality. It might be some missing initialization for the locally generated replies reason phrase.  -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3287 You are receiving this because you are subscribed to this thread.
