The use of devices, such as Fixed Mobile Convergence (FMC) devices, enables a user on a call to have the connection seamlessly transition from one network to another. However, a call that is disconnected, either pre-answer or post-answer, leaves the calling party without information as to why the call was disconnected. Herein, systems and signaling methods are provided whereby a reason for a disconnect can be created and passed to the calling party, such as in a text message, to inform the caller of the disconnect reason. Additionally, the reason may be provided to the called party's voicemail. The call server may then connect the calling party to the voicemail and, with the reason code, the voicemail server is able to announce the reason for the disconnect and provide the calling party the opportunity to leave a message for the called party. The called party, when available, may then be presented with the voicemail.
