<br>
The dialog module does TH at SIP level (and not at RTP level) -
if you want to do that, we need to use (in conjunction to dialog
TH) a media relay (as mediaproxy or rtpproxy) in order to hide
also the RTP side.<br>

<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>

<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>
