[SIPForum-discussion] the difference of proxies, user agent servers, redirect servers, and registrars?

HI, gogofly_lee

All the servers you've mentioned are LOGICAL entities, and RFC3261
interprets them respectively in Section 6.
I think study some products that implements RFC3261 will help you make the
server concept more clearly, Openser is recommended, http://www.openser.org
