<div><tt>Hi,<br>
<br>
the dialog based topology_hiding() DOES handle the BYE if you do
proper routing (you do not need B2B). What you need to do is to
change in your script (where you handle sequential requests,
with to-tag) from:<br>
if (loose_route() ) {<br>
<br>
into<br>
<br>
if (loose_route() || match_dialog() ) {<br>
<br>
Regards,<br>

<div>I am looking for top hiding and i tried
topoloy_hiding() but it doesn't handling BYE mesg so i
am planing to go with B2B. I have few question<br>
<br>
</div>
1. Does B2B work like Proxy?<br>
</div>
2. Does B2B support NAT SIP client? <br>
</div>
<br>
</div>
Or should i install Opensips proxy and B2B opensips on same box
and interconnect them? <br>
</div>
