发明名称	Policy control and billing support for call transfer in a session initiation protocol (SIP) network
摘要	A session initiation protocol (SIP) server adds billing and authentication information to conventional SIP messages used in establishing call transfers. This additional information is later verified by a SIP server and used to enable advanced billing and fraud protection features for call transfers in a SIP telecommunications network.
