摘要： A method of call routing is provided. The method comprises receiving a session initiation protocol (SIP) INVITE message that contains a uniform resource identifier (URI) of a called party and that identifies that a bearer for a call to the called party is to be set-up at least in part over the circuit switching domain. The method also comprises determining a digit string associated with the URI. The method also comprises sending a SIP informational response message having a contact header that contains information based on the digit string.

摘要： A method for determining trust for SIP messages. The method includes receiving a Uniform Resource Identifier (URI) in a header field in a first Session Initiation Protocol (SIP) message, receving a token in the header field in the first SIP message, the token indicative of a type of a network node in a path of the first SIP message, and based on the received token, sending a second SIP message including the received URI, the second message conveying information about the first network node.
