From: [EMAIL PROTECTED] (Juha Heinanen) it would be nice if it would be easy implement a redundant, load balancing sip proxy cluster, where each proxy would be able to serve any UA.
Speaking as someone who has implemented a redundant, load-balancing SIP proxy cluster: It would be nice if it can be done easily, but that isn't possible. You need very disciplined inter-proxy communication to allow the UA to "register against one proxy" and yet be served by all proxies. (See http://sipxecs.sipfoundry.org/rep/sipXecs/main/sipXregistry/doc/SyncDesign.txt for the details.) the only thing i was trying to say is that things would be much simpler and more efficient if there would not need to be any inter-proxy communication. I don't see how you can avoid inter-proxy communication unless the UA maintains a separate registration with each proxy. And even if the UA does maintain a separate registration with each proxy, since the proxies are load-balancing, any proxy can receive a request, and if it does not have a path to the destination UA, it needs to know how to send the request to a proxy that does have a path to the destination UA.
