Hi.. That is the whole issue,,, The proxy 1 and proxy2 do not know each other. How can I configure openser so that it recognizes proxy1 as another proxy and sends/receives invites? I do not want any of the proxies acting as out bound proxy. Both should be primary proxies for their respective domains and yet they should be able to recognize the other proxy and forward the requests to it. In other words, what I am asking how do the proxies talk to each other?

I wish to make a call from UA 1 to UA 2. Proxy 1 and proxy 2 are in the LAN but do not know of each other. Is there a way we can configure the openser to send/receive the invites to proxy 1? I think the calls will be handled on domain basis, so openser will treat all the UAs registered to it as local and allow them to call each other. But how to make it allow inter domain calls? Please let me know.
