It seems that what you want is third party registration. I'm pretty
sure you can tell OpenSER to register your users on your other SIP
server by diverting the 'REGISTER' request.<br><br><div><span class="gmail_quote">2006/4/4, Jeff Williams <<a href="mailto:jeffw@globaldial.com">jeffw@globaldial.com</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
We have a commercial SIP server which currently does our registering,<br>low cost routing and customer billing. However, it doesn't handle NATed<br>connections well. To fix this, I wanted to use openser in front of it<br>
for customer connections using mediaproxy/rtpproxy. However, I have a<br>problem with this setup.<br><br>>From what I gather, for the proxy to work properly, the end user need to<br>be registered with the proxy so that it can do nat pings and keep the
<br>nat connection alive. But for users to make calls using our commercial<br>server (which is what we want), they must be registered there. Is it<br>possible (or even a good idea) to have a user registered on 2 servers at
<br>the same time? How else can we do this?<br><br>This is what I want to achieve:<br>- from the end user perspective, they register and initiate calls only<br>via the openser proxy. They know nothing of our commercial server.
<br>- calls between users is done on the openser proxy<br>- calls to external destinations (i.e. PSTN) go via our commercial<br>server and require that the user is registered there<br><br>Is this possible?<br><br>Jeff<br>
