Another very useful use case is in "attended call transfer" where in the the
SIP URI in Refer-To header shall contain "replaces" header.

For example, if I want to place SIP URI(s) as hyper-link and if I want a
certain headers to be part of SIP request that will be generated on clicking
the link, i shall include headers as part of the SIP URI.
