<p class="MsoPlainText">Trying to upgrade my platform to OpenSIPS 2.4.2 (yea, about time, I know).<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">We use this to move established calls from one server to another:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">/usr/local/sbin/opensipsctl fifo b2b_bridge <tupleID> <a href="sip:555@1.2.3.4">
sip:555@1.2.3.4</a> 0<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">This works fine with OpenSIPS 1.8. The above causes this:<o:p></o:p></p>
<p class="MsoPlainText">1. Invite (reinvite) to caller with no sdp.<o:p></o:p></p>
<p class="MsoPlainText">2. RX of 200 OK with SDP from caller<o:p></o:p></p>
<p class="MsoPlainText">3. Invite with SDP to 1.2.3.4<o:p></o:p></p>
<p class="MsoPlainText">4. RX of 200 OK with SDP from 1.2.3.4<o:p></o:p></p>
<p class="MsoPlainText">5. OpenSIPS send ACK WITH SDP to caller.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Call moved. All good.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">With OpenSIPS 2.4.2:<o:p></o:p></p>
<p class="MsoPlainText">1. Invite (reinvite) to caller with no sdp.<o:p></o:p></p>
<p class="MsoPlainText">2. RX of 200 OK with SDP from caller<o:p></o:p></p>
<p class="MsoPlainText">3. Invite with SDP to 1.2.3.4<o:p></o:p></p>
<p class="MsoPlainText">4. RX of 200 OK with SDP from 1.2.3.4<o:p></o:p></p>
<p class="MsoPlainText">5. OpenSIPS send ACK WITHOUT SDP to caller.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">With 2.4.2, I get one way audio, very likely because of the lack of SDP in the ACK in point 5.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">My research does not lead me anywhere on how why this behaviour changed between 1.8 and 2.4.2. I can't find any flags to set to get b2b_bridge command to have to old behaviour.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Help!<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">regards,<o:p></o:p></p>
