Hi RFC3515 defines the REFER method and the Referred-to header. What is not clear from this RFC is how to populate this header.
RFC3515, ch 2.1 defines the syntax, but that doesn't give much information. There are a number of example in chapter 2.1, but I fail to understand these examples after reading this RFC. The RFC contains in chapter 2.4.3 the following text The resource identified by the Refer-To URI is contacted using the normal mechanisms for that URI type. For example, if the URI is a SIP URI indicating INVITE (using a method=INVITE URI parameter for example), the UA would issue a new INVITE using all of the normal rules for sending an INVITE defined in [1]. This text describes that the Referred-to can contain a URI parameter (method=INVITE), with some implied behavior. However I can not understand the above text based on reading this RFC. I hope somebody can provide some more explanation of how to understand a Referred-to header.
