Thanks for the reply, I will try that for sure :)<br><br>Just to clarify, so whatever I had on request route and reply route (including rtp proxy and nathelper methods) should be written on b2b_request and b2b_reply, right ?<br>

<tt>Hi Dinusha,<br>
<br>
How I see it is: do LB, after LB, trigger B2B with REFER-handling
scenario, and on the outbound part of b2b (using local route for
INVITE and b2b_reply for incoming replies) insert rtpproxy. <br>
<br>
Of course, I assume that LB and B2B are on the same instance of
OpenSIPS.<br>

<br>
I currently have my opensips configured with a rtpproxy and uses
the nathelper module and everything seem to be working fine.<br>
<br>
Now, I have a new requirement where my opensips should have to
handle REFER messages generated from a media server and I'm not
sure what I should do.<br>
<br>
I've seen that b2bua module is capable of this and I also had a
look at the example done on <a href="http://opensips.org" target="_blank">opensips.org</a>.<br>
<br>
Here's my scenario,<br>
<br>
User1(softphone) calls opensips server and opensips do load
balancing and redirect the call to a Media Server. Then, Media
Server will send a REFER message to opensips specifying a refer-to
User2(another softphone) and the media server should remove itself
from the call and let User1 and User2 connect to each other
through opensips.<br>
<br>
Here are my questions :<br>
<br>
1) The rtpproxy module re-writes SDP and how does this affect if I
use b2bua module to handle REFER messages ?<br>
2) Will the work done by nathelper and rtpproxy be undone if I
call b2b_init_request on the initial INVITE ?<br>
3) Do I have to have a separate IP for b2bua server or is it ok to
run it on the same ip which the opensips is running ?<br>
4) I have seen some people block the INVITE's coming from b2bua
server IP at initial INVITE.. do I have to do this too ?<br>
<br>
Thank You, :)<br>
<br>
Regards, <br>
Dinusha. <br>
