    Hello,<br>
    <br>
    SIP call comes on leg A as following:<br>
    INVITE sip:<a href="tel:6135555555" value="+16135555555" target="_blank">6135555555</a><b>;npdi=yes</b>@<a href="http://1.2.3.4:5060" target="_blank">1.2.3.4:5060</a> SIP/2.0<br>
    <br>
    ${destination_number} var becomes &quot;<a href="tel:6135555555" value="+16135555555" target="_blank">6135555555</a>;npdi=yes&quot;<br>
    <br>
    On leg B I send the call to gateway using unaltered
    ${destination_number}:<br>
    &lt;action application=&quot;bridge&quot;
    data=&quot;sofia/gateway/test_gw/${destination_number}&quot;/&gt;<br>
    <br>
    I see the following on leg B:<br>
    INVITE <a href="mailto:sip:6135555555@5.6.7.8:5060" target="_blank">sip:6135555555@5.6.7.8:5060</a><b>;npdi=yes</b> SIP/2.0<br>
    <br>
    So, FS moved &quot;;npdi=yes&quot; which is a tel URI parameter into the very
    end as if it was a SIP URI parameter. Such behavior does not seem
    correct. Is this a bug? Found the following implementation
    discussion:<br>
    <a href="http://comments.gmane.org/gmane.ietf.sip-implementors/21554" target="_blank">http://comments.gmane.org/gmane.ietf.sip-implementors/21554</a><br>
    <br>
    Please help to make FS send tel URI parameters unaltered using
    bridge application and a gateway. WiKi for bridge dial-plan tool has
    some examples but it does not make use of gateway and I need to use
    gateway.<br>
    <br>
    Thank you,<br>
    Victor
