[SR-Users] Re: uac_req_send + evroute + crash

Hello,   I used kamailio version 5.6.2. I refreshed to 5.7.2 today. As I remember it was in kamailio long time ago therefore I could skip evroute route. But this CRITICAL log appears always when I call uac_req_send(). I call it with settings: $uac_req(auser)= $var(username); $uac_req(apasswd)= $var(password);   Where username and password are retrived from web service before call. In event_route I got first 401 after 200.   *Peter*     *From: *Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; *Date: *Thursday, 2023.
