You may want to look at draft-mahy-sip-remote-cc-03 for call control of UA which use cti applications. What are the things that call flow using REFER does not cover?

One thing that I have not been able to gain any clear resolution in my mind about is how third party call control for UA's (i.e. by CTI applications) is defined, I have come across mention of the SIP REFER in passing but this does not seem to handle such things in entirety. In my mind I would imagine a tasteful proxy may be able to influence call interaction for a UA/SIP end point (comments?). Does anybody have any insight in this regard?
