[reSIProcate] Forking with DUM

[Scott Godin]

Forking is normally provided by a proxy not a UA, so DUM is setup to
be able handle it's calls getting forked, but it is not currently
inteded to be used to actually perform a fork.  I'll assume you are
writing some form of B2BUA - why not just initiate multiple outbound
calls with seperate AppDialogSet's, and use some common userdata in
order to associate them all together?
