In wireshark, there are 2 fields - Source and Destination. I am curious if there are variables in Kamailio which can show me those values.<div>System:</div><div>MYIP - IP of kamailio</div><div><a href="http://sip.mydomain.com">sip.mydomain.com</a> - address of kamailio</div>
<div><br></div><div>User (Imsdroid for Android) ->Kamailio->Asterisk->Kamailio (same) ->Other user.</div><div>Problem - register, voice, video, and ring are OK, but ACK and BYE are going in dead loop - and this happens may be around in 50% of cases - not in all cases.</div>
<div>If I am using other client (like hardware SIP phones), then I have no problems, but it is really hard to find some client for Android which supports video with Kamailio.</div><div>To solve problem, I made one function in Kamailio.cfg - ACKBYE, which is called only within dialog. And within dialog is called in main route.</div>
<div><div>route[ACKBYE] {</div><div>#!ifdef WITH_MYFORWARD</div><div>xlog("SCRIPT: AckBye $td;$si;$du;$dd\n");</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>if((($td=="<a href="http://sip.mydomain.com">sip.mydomain.com</a>")||($td=="MYIP"))&&($si=="MYIP")){</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>$du=$sht(forw=>$ft);</div><div>xlog("SCRIPT: AckBye2 $td;$si;$du\n");</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>return;</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>}</div><div>#!endif</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>return;</div><div>}</div></div><div>Of cource I have</div><div><div>
<span class="Apple-tab-span" style="white-space:pre"> </span>if(is_method("INVITE")){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>ds_select_dst("1","4");</div><div>
<span class="Apple-tab-span" style="white-space:pre"> </span>$sht(forw=>$ft)=$du;</div></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>}</div><div>This worked for long time. But then we updated client (libraries etc), and problem appeared again - from time to time. Calls between 2 same clients can pass 2 or 5 times, and then problem appear.</div>
<div>Before - $td and $si showed destination and source but now there is difference:</div><div><div>ERROR: <script>: SCRIPT: AckBye 192.168.2.251;MYIP;<null>;<null></div><div>$td in this case show destination, which is correct, but in wireshark, destination and source = MYIP. </div>
