Click to Dial is only one aspect of 3pcc. A 3pcc'er can do all sorts of good and bad things associated with the call. I'm not saying 3pcc can't be done using REFER. However as I indicated, one of the goals of rfc3725 was to use basic sip instead of requiring exentions such as REFER. The are a few of the the drafts discussing call control using SIP extensions. http://tools.ietf.org/html/draft-ietf-sipping-cc-transfer http://tools.ietf.org/html/draft-ietf-sipping-cc-framework _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
