The term 'softswitch' is not defined in SIP.  Rather, the term 'proxy' 
is defined (in RFC3261).  The big difference between a SIP proxy
and an SBC is which SIP headers are changed and if the SDP is changed.
A SIP proxy doesn't modify the SDP; an SBC does (in order to
cause the media stream to be directed to the SBC or to a DBE (data
border element)).
