<p><tt>Hi Jim,</tt></p>
<p><tt>Both functions attempt to rewrite the Contact - the former
with SOURCE_IP:SOURCE_PORT, while the latter attempts to do it
with ADV_IP:ADV_PORT. Due to the "lazy changes" optimization of
the OpenSIPS stack, you cannot serialize these two function
calls, rather you are forced to pick one of them.<br>
</tt></p>
<p><tt>Fortunately, there is another way around the above: you can
have the mid-registrar insert itself through a Path header,
rather than rewriting the Contact to point to its interface. So
just switch the mid_registrar to "insertion_mode = 1" and you
should be good.<br>
</tt></p>
<p><tt>PS: can you elaborate on what you are trying to achieve?
IIRC, fix_nated_contact() should not be called on a REGISTER,
rather you should use the fix_nated_register() which forces a
";received=" param into the Contact. Conceptually, at least -
I'm pretty sure this also won't work well with
mid_registrar_save().<br>
</tt></p>
<p><tt>Best regards,</tt><br>

<div><br>
</div>
<div>So if I call fix_nated_contact(); before
mid_registrar_save(); It will correctly rewrite the Contact
URI with the recived IP:PORT however it mid_register is then
not able to append the contact_match_param to the new Contact
URI. </div>

<div>The script looks like this...</div>

<div>
<div>if (is_method("REGISTER")) {</div>
<div> fix_nated_contact();</div>
<div> mid_registrar_save("location");</div>
</div>
<div><br>
</div>
<div>It fails with this error. <br>
