Summary: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 mail server (151) of said time division multiplex network (PSTN).
