ABSTRACT:
In one embodiment of the invention, a method produces a hook status notification. The method comprises detecting an off-hook state, allocating a half-dialog identification, generating an off-hook notification message, and associating the half-dialog identification with the off-hook notification message. In an alternative embodiment, a communication platform is adapted to comprise a processor component operable to receive an off-hook notification message comprising a half-dialog identification, and to store the half-dialog identification. The communication platform subsequently receives a signaling protocol message initiating a dialog, wherein the signaling protocol message is associated with the half-dialog identification. The communication platform then correlates the second signaling protocol message with the stored half-dialog identification.
