Hi all,<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">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>
