3.2.5.5 Call-Disconnect–Notify Message

The Call-Disconnect–Notify message is a PPTP control message sent by the PAC to the PNS. It is issued whenever a call is disconnected due to the receipt by the PAC of a Call-Clear-Request message or for any other reason. The format of this message is specified in [RFC2637] section 2.13. The PAC MUST set the value of the Result Code field in this message to 0 irrespective of the reason for the disconnection, including general error conditions, as specified in [RFC2637] section 2.13. The PNS MUST ignore the value of the Result Code field in this message.
