Hi , I have a question regarding the Attended-Transfer type call flows.
I am searching for the best method to allow the transferee to receive the early media stream sent by transfer target. During the initial phase of the transfer (before sending REFER request to the transferee) we establish a dialog between the transferor and the transfer target. During the dialog establishment, the transfer target might send early media stream (i.e. ringback tone). Since the transferee is not a party in this dialog, the early media stream is not relayed to the transferee. This of course affects the transferee user experience. I did no find standard practice for this issue in draft-ietf-sipping-cc-transfer. Would appreciate suggestions for implementing this feature.
