    <tt>Hi B<tt>en,<br>
        <br>
        <tt>The fix is p<tt>resent on trunk <tt>(2.4)<tt>, 2<tt>.3 and
                  2.<tt>2 (the curren<tt>tly maintained versions).
                      Indeed, the 1.11 does not have the fix. <tt>You
                        can easily <tt>apply the fix on<tt> your 1.11
                            code <tt>vi<tt>a this patch -

                                . It should be <tt>100% co<tt>mpatible.
                                    <br>
                                    <br>
                                    <tt>Other<tt>wise, you can try to
                                        get rid of user=phone in th<tt>e

            style="font-size:10.0pt;font-family:"Courier New""><br>
            <br>
            <tt>Thank you for your digging and reporting. Following your
              leads I found some old strange behavior of the parse_uri()
              function - the function responsible for parsing the URIs
              in OpenSISP.
            </tt><br>
          </span><br>
          <br>
          <o:p></o:p></p>
        <pre>For some ancient and unknown reasons, a SIP URI with user=phone was automatically converted to a TEL URI. Such conversion, automatically done, is dangerous - there is nothing in the RFC3261 stating something like this. Even more, the conversion is not complete - besides moving the username parameters to URI parameters, the domain is not stripped and the TEL not added.<o:p></o:p></pre>
        <pre><o:p> </o:p></pre>
        <pre>Basically, the existing code was converting:<o:p></o:p></pre>
        <pre>        <a moz-do-not-send="true" href="sip:username;bla=foo@host.com;param1=1;param2=2;user=phone">sip:username;bla=foo@host.com;param1=1;param2=2;user=phone</a><o:p></o:p></pre>
        <pre>to<o:p></o:p></pre>
        <pre>        <a moz-do-not-send="true" href="sip:username@host.com;bla=foo">sip:username@host.com;bla=foo</a><o:p></o:p></pre>
        <pre><o:p> </o:p></pre>
        <pre>I tried to dig around the subject, but not more - there is no reference or recommendation for such a behavior. If you have the time, see these links:  <o:p></o:p></pre>
        <pre>* SIP implementer -> <a moz-do-not-send="true" href="https://lists.cs.columbia.edu/pipermail/sip-implementors/2013-February/028837.html">https://lists.cs.columbia.edu/pipermail/sip-implementors/2013-February/028837.html</a><o:p></o:p></pre>
        <pre>* SIP Core -> <a moz-do-not-send="true" href="https://www.ietf.org/mail-archive/web/sipcore/current/msg01783.html">https://www.ietf.org/mail-archive/web/sipcore/current/msg01783.html</a><o:p></o:p></pre>
        <pre>* voip info -> <a moz-do-not-send="true" href="https://www.voip-info.org/wiki/view/SIP+URI">https://www.voip-info.org/wiki/view/SIP+URI</a> (Telephone numbers section)<o:p></o:p></pre>
        <pre><o:p> </o:p></pre>
        <pre>On voip-info there is a recommendation on how to compare a SIP uri with a TEL uri (in terms of username and parameters parts), but nothing of a "must" conversion.<o:p></o:p></pre>
        <pre><o:p> </o:p></pre>
        <pre>So, I disabled the guilty code in OpenSIPS, and it should work as expected now.<o:p></o:p></pre>
