What is the difference between Dialog Stateful proxy and Call Stateful proxy?
Can you pls add info to Registration Stateful proxy also? RadhaKrishna.

Whether it is stateful or not, a proxy must obey certain rules (in 3261) about what it may, and may not, do. A UA has different, less restrictive rules. A B2BUA *can* function in a manner similar to that of a proxy, in that messages coming in one side typically result in a related message going out the other side. But because it is a UA to can do things a proxy is not permitted to do. For instance, a node could act exactly like a proxy, but store dialog state. (Hence be a "stateful proxy".) At some point it might use that state to enable it to send a BYE, terminating the dialog. At the moment it does that it ceases to be a proxy and becomes a B2BUA. Note that neither B2BUA nor Stateful Proxy are very precise terms. B2BUAs can be very much like proxies, as above. But there are other kinds of B2BUAs, such as conference foci and 3pcc controllers, that bear little resemblance to a proxy. Stateful proxies vary depending on how much state they contain. At the simplest level there are stateless proxies, transaction stateful proxies, dialog stateful proxies, call stateful proxies, and registration stateful proxies.
