This invention relates to the field of IP telephony. More particularly, this invention is a method for handling the signaling related to the storing and forwarding of voice and video messages in an IP based network. With reference to Fig. 1, this invention is a method for signaling an IMS (25) on an IP based network (17) to perform an action on a message, where the action is either a deposit of the message or the retrieval of a previously deposited message, including the steps of sending an SIP INVITE request from a network server (23) to the IMS (25) indicating the desired action; receiving a corresponding SIP message from the IMS (25) agreeing to participate in the desired action; and sending an SIP acknowledge message from the network server (23) to the IMS (25) confirming receipt of the corresponding SIP message; and performing the desired action. |
