Abstract

A method is disclosed of providing a message wait service to the users of an IP based telecommunication network (IPBN). For the invocation of a message wait service by a calling user, when said VOIP user is busy or not answering a call, or has forwarded all the calls unconditionally to a voice mail server, the method comprises the steps of : sending (201) from a proxy server (104), which takes care of redirecting the calls of said VOIP user (100), to a media gateway controller (102) of the IP based telecommunication network (IPBN), a message INVITE comprising a diversion header containing a diversion reason : user-busy, or no-answer; generating, in said media gateway controller (102), some procedure code for invocation of a message wait service provided by a voice mail server (151) in a time division multiplex network (PSTN), when said media gateway controller (102) receives said message INVITE; and then sending (202, 203) said procedure code, in an IAM message, towards said voice mailserver (151) of said time division multiplex network (PSTN).

Description

technical field [0001] The invention relates in particular to a method of providing a Message Waiting Service (MWS) to users of Internet Protocol (IP) based telecommunication networks. Background technique [0002] The MWS provides the serviced user with the ability to redirect the user's voice calls to an external system capable of recording messages, and said system is known as a Voice Mail Server (VMS). These messages are stored in the subscriber's voice mailbox. If the service is active, redirection of the call is done when one of the following events occurs: [0003] - called user is busy, [0004] - the called user cannot reply within a certain period of time, [0005] - or unconditional forwarding to VMS is activated. [0006] The called user is notified by the VMS when at least one message is waiting. Once the subscriber has listened to all messages in the mailbox, no further notifications of any pending messages are sent. This MWS is made available to users of...
