Hi all<div>I need some help with an error that have been for three days in my log.</div><div><br></div><div>This is the situation; I needed to "mask" the from header of everything that comes from a given ip address. So, everything that comes from ip address x.x.x.x, with from header: anypeer@x.x.x.x, opensips change the from header to <a href="mailto:sip%3Aotherpeer@mydomain.com">sip:otherpeer@mydomain.com</a> </div>
<div><br></div><div>These are the lines of interest in opensips.cfg</div><div><br></div><div><div>#--- Routing to the PSTN section ---#</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>if (uri=~"^sip:(00|011|09|555|995|996|997|998)[0-9]*@") </div>

<br>Now, some calls coming from this ip, are established without problems, but some other don't showing this error

</div><div><b><br></b></div><div>Now, doing some google on that error, i found out that it is caused by a BYE sending before a call is established, something like this:</div><div>INVITE ------></div><div> <----- trying, ringing</div>
<div>BYE -------> </div><div><br></div><div>The BYE message is being send bye the UAC instead of a CANCEL message. I don't know why, it seems to be a UAC missfunctioning</div><div><br></div><div>As I said before, not every call coming from this ip fails in this error. And it is not a problem of a single peer or group of peers. Sometimes peer 123456 succeds and sometimes don't.</div>
<div>I<b>s there something else i can check in opensips that i am missing out?</b></div><div><br></div><div><br></div><div>Here a capture of packets of one call that give error. </div><div><br></div><div><div>U x.x.x.x:5060 -> opensips_ip:5060</div>
