<div dir="ltr">Hi,<div><br></div><div>this is actually fully SIP/RFC compliant. By definition, any 6xx answer provides the "ultimate, global answer", to put it in simple words: "I cannot reply to the request and I know no one else can". On the contrary as per the definition/RFC, a 5xx answer indicates, that a single endpoint is not able to handle the request (temporarily) due to technical reasons, while others still may be able to answer this.</div><div><br></div><div>The right answer would be, that the SIP endpoint should respond with a 4xx Answer to indicate that the call was declined on a user-based decision or status (e.g. "busy").</div><div><br></div><div>I haven't tried this, but maybe you can check the following parameter:</div><div><a href="https://opensips.org/docs/modules/3.4.x/tm.html#param_disable_6xx_block">https://opensips.org/docs/modules/3.4.x/tm.html#param_disable_6xx_block</a><br></div><div><br></div><div>This parameter should change the behavior on receiving a 6xx reply - however, I never tried it myself.</div><div><br></div><div>Thanks,</div><div>Carsten</div><div><br></div><div><br></div><div><br></div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr">--</div><div dir="ltr">Carsten Bock I CTO & Founder</div><div dir="ltr"><br><p style="margin:0cm 0cm 0.0001pt;background-image:initial;background-position:initial;background-repeat:initial"><span lang="EN-US" style="color:black">ng-voice GmbH</span><span lang="EN-US" style="color:rgb(0,112,192)"><u></u><u></u></span></p><p style="margin-right:0cm;margin-bottom:12pt;margin-left:0cm;background-image:initial;background-position:initial;background-repeat:initial"><span lang="EN-US" style="color:black">Trostbrücke 1 I 20457 Hamburg I Germany<br>T +49 179 2021244 I <a href="http://www.ng-voice.com/" style="color:rgb(17,85,204)" target="_blank"><span style="color:black">www.ng-voice.com</span></a><u></u><u></u></span></p><p style="margin:0cm 0cm 0.0001pt;background-image:initial;background-position:initial;background-repeat:initial"><span lang="EN-US" style="color:black">Registry Office at Local Court Hamburg, HRB 120189<br>Managing Directors: Dr. David Bachmann, Carsten Bock</span></p></div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Am Di., 25.

I had set up a opensips service on my Ubuntu 18.04.6 , and opensips version: opensips 3.2.6 (x86_64/linux).
<br></font></pre><font style="line-height:23.8px;display:inline;font-family:monospace;background-color:rgba(0,0,0,0)"><pre style="line-height:23.8px;background-color:rgba(0,0,0,0)">When I test that case, I use two desktop linphone login same sip accout 01010101 (callee A/B). and I use my Android linphone(caller C) invite A/B, A/B rings together which works well.
but I hang up the callee A , B also terminated .
I use wireshark to capture the packet on server side. it show that :
1. when callee A(192.168.2.123) hand up, it respond 603 to the server(192.168.2.108)
2. server(192.168.2.108) forwards the respond 603 to caller C(192.168.2.115)
3. server(192.168.2.108) create a CANCEL to callee B(192.168.2.127)
so, it seems opensips server CANCEL B automatically. </pre></font><pre style="line-height:23.8px"><br></pre><pre style="line-height:23.8px"><font style="line-height:23.8px;display:inline;background-color:rgba(0,0,0,0)">My project need to meet the ability that callee A declines but callee B still ring.
