<tt>Hi,<br>
<br>
You can do TH with nathelper, BUT be sure to create the dialog +
TH AFTER doing the fix_nated_contact().<br>
<br>

<div>Topology hiding limitations</div>
<div>You cannot easily combine topology hiding with NAT
traversal because both the</div>
<div>processes mangle the Contact header. Topology hiding will
not hide the address and</div>
<div>other information contained in other headers such as the
display in the From header.</div>
<div>To change the From header, you can use the
uac_replace_from() function.</div>
</div>
<div><br>
</div>
<div>I think our problem comes from the fact that we are using
nathelper and also an rtpproxy in our script.</div>
<div><br>
</div>
<div>can anyone provide help about activating topology hiding
along with nathelper ?</div>
