FYI: The term "Re-INVITE" is wrong in this scenario. The proxy just 
forwards the INVITE doing parallel forking (in openser terminology: 
creates multiple branches). As sson as one phone picks up, this branch 
is the winning branch and the other branches will be canceled.

A reINVITE is an in-dialog INVITE, e.g. used for modifying the media 
session (putting the call on hold, enable/disable video ...)
