- Later alice sends a REFER or a re-INVITE. Note that the request
would contain "From: sip:200@domain.org" (even if the AoR of alice us "sip:alice@domain.org". This is because From/To URI are usually unchanged whithin a dialog.
inaki,
refer would contain header
Referred-By: sip:alice@domain.org
which k would use for Proxy-Authorization.
Hi Juha, Referred-By header is not part of REFER specification but an extension (RFC 3892) and it's not mandatory:
2.1. Referrer Behavior
A UA sending a REFER request (a referrer) MAY provide a Referred-By header field value in the request.
