The SIP Call Transfer and Call Forwarding Supplementary Services feature introduces the ability of 
Session Initiation Protocol (SIP) gateways to initiate blind or attended call transfers. Release Link 
Trunking (RLT) functionality was also added with this feature. With RLT, SIP blind call transfers can 
now be triggered by Channel Associated Signaling (CAS) trunk signaling. Finally, the SIP Call Transfer 
and Call Forwarding Supplementary Services feature implements SIP support of call forwarding 
requests from a Cisco IOS gateway.
