The Sip Refer Method Draft-ietf-sip-refer-05

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." Abstract This document defines the REFER method. This SIP extension requests that the recipient REFER to a resource provided in the request. This can be used to enable many applications, including Call Transfer.
