[SR-Users] Hangup call on leg B side

[Alex Balashov]

This is impossible, by definition, with a proxy.  That is because a 
proxy is a proxy, not a back-to-back user agent (B2BUA), so it does not 
create two different, logically independent call legs and bridge them. 
Instead, one call leg A comes in, and that same call leg B goes out.
