Hello All,
Few more notes about my draft.
The question is, should the Ctg request the caller (RFC 3891) or the callee to pick up a call? 
The former, in addition to charging issues, brings up the following:
1. Routing to the caller, which could be hindered by line hunting. I know there is a recently 
published RFC about this.
2. Call barring policy at either side.
3. Information for the callee only (if it could be). Clearly, this is not possible with RFC 3891. It 
is not specified in draft-worley-sipping-pickup-01, nor in draft-tveretin-dispatch-remote-00, but 
will be in -01 version (Subject: header).
Of course, I do not want to restrict applicability of the RFC 3891.
Regards,
Anton.
