Hi there,<div><br></div><div>I am having a problem using the OpenSIPs installation on the website <a href="http://opensips.org">opensips.org</a> (the one that's free to register for). Whenever I send a MESSAGE it appears to be sent to the client twice. In my packet capture I can see a MESSAGE being received from my client and then it sends a 200 response. And then another message is received and another 200 response. The two MESSAGE from the server are exactly the same. This is duplicated with different clients.</div>
<div><br></div><div>Here is my contact information for when I login (I've changed the IP's for security obviously):</div><div><br></div><div><span class="Apple-style-span" style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 18px; -webkit-border-horizontal-spacing: 7px; -webkit-border-vertical-spacing: 7px; "><table border="1" cellpadding="3" cellspacing="0" align="center" class="swTable" style="border-top-width: 1px; border-right-width: 1px; border-bottom-width: 1px; border-left-width: 1px; border-top-style: solid; border-right-style: solid; border-bottom-style: solid; border-left-style: solid; border-top-color: rgb(255, 187, 102); border-right-color: rgb(255, 187, 102); border-bottom-color: rgb(255, 187, 102); border-left-color: rgb(255, 187, 102); ">

It is quite easy to cater to this (compare the previous MESSAGE to the next and if they are the same drop them) but I haven't seen this behaviour documented anywhere.</div>
<div><br></div><div>Could somebody out there enlighten me as to the expected behaviour?</div><div><br></div><div>Kind regards,</div><div>Andy</div>
