<div dir="ltr">Hi Donat, <div><br></div><div>According to Saurabh , he is saying in " <b>db_mode=3 and sql-only mode</b> " that direct DB operation happens . </div><div>When a user get registered that contact immediately get populated to the DB and when the user send un-registration the entry from the DB should be deleted at that time . </div><div><b>The deletion part is not happening in his case </b>.<b> The contact from location table delete when in the expiration time</b> .</div><div><br></div><div>According to opensips documentation , the timer works when the user not able to un-registrer itself . Then data persist in the DB . That should be deleted in the timer interval . This is fine . </div><div><br></div><div>If I will explain through example . </div><div>1. Usr get register at 11.10.10 with expire 300sec . </div><div>2. User send un-register at 11.11.10 (But the data wont get deleted from the DB somehow)</div><div>3. The user was gone away in 1min only . But the data in DB is there for next 4min . <b> In this case the timer wont play any role . Even though <span style="background-color:rgb(254,254,238);color:rgb(0,0,0)">timer_interval is set to 120sec . Still the contact exists till 5min . </span></b></div><div>4. If an INVITE will come for that user . Then opensips will try to push the call to that existing contact . But I was expecting 404 Not Found . </div><div><br></div><div>This is the problem . As for the previous version of opensips this is working fine . But in 3.1 we are facing issue . </div><div><br></div><div>I have taken opensips code from </div><div><pre style="font-size:0.9em;font-family:"Lucida Console","Andale Mono","Courier New",Courier;margin-top:0px;margin-bottom:0px;color:rgb(102,102,102)"><strong><code class="escaped" style="font-size:11.7072px;font-family:"Lucida Console","Andale Mono","Courier New",Courier;padding:6px;border:1px solid rgb(235,235,235);background-color:rgb(251,254,250);white-space:nowrap">git clone <a href="https://github.com/OpenSIPS/opensips.git">https://github.com/OpenSIPS/opensips.git</a> -b 3.1 opensips-3.1</code></strong></pre></div><div><br clear="all"><div><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div><div><b><i>Please suggest what else we should do .</i></b></div><div dir="ltr"><b><i><br></i></b></div><div dir="ltr"><b><i>Thanks & Regards</i></b><div><i>Sasmita Panda</i></div><div><i>Senior Network Testing and Software Engineer</i></div><div><i>3CLogic , ph:07827611765</i></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Dec 14, 2020 at 5:13 PM Donat Zenichev <<a href="mailto:donat.zenichev@gmail.com" target="_blank">donat.zenichev@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr">Good day Saurabh, could you refer to the RFC and the particular row in that, that talks about a backend database and time in which the row should be deleted from that?<br>I just wonder if I missed this somewhere.
