Patent ID: 8576838

Claim:
A method of setting up a call-back to a caller in a packet-based telecommunications network, the call-back being initiated by a user receiving a media stream comprising data related to the caller, whereby the method comprises the steps of: setting up by the user a packet-based connection to a media server and receiving the media stream from the media server; after choosing by the user to call back the caller, generating by the media server a cookie with data defining a state of the media stream, and sending by the media server a signaling message and the cookie to the user for initiation of a call transfer; inserting an indication as a parameter of a contact header of the signaling message wherein the indication specifies that the user may call back the media server or the associated media server after termination of the call-back, the signaling message using a packet-based signaling protocol; initiating by the user the call-back to the caller independently of the media server; and after termination of the call-back, sending by the user an invitation message and the data defining the state of the media stream to the media server or an associated media server and using the data defining the state of the media stream to resume the transmission of the media stream to the user from a state following the state defined by the data.
