Hi<br><br>How can we set the expires value of the REGISTER OK sent back to the clients in a dynamic way ?<br><br>We set already a value with <br><pre style="margin-left: 40px;" class="programlisting"><font size="4">modparam(&quot;registrar&quot;, &quot;max_expires&quot;, 120)</font><br>

</pre>but if the UA has been detected to be behind a NAT we want to apply a different value.<br><br>Regards,<br>Pascal<br>
