Symptom: (**Note: please see CSCtd60961 for the entire fix to this issue**) Call not cleared when MWI comes in via SIP notify. This problem exists when Unity integration is SIP or the new SCCP StationMwiNotificationMessage. Conditions: MWI comes in via SIP notify, which goes across an ICT. Call across ICT is not torn down after MWI operation is completed. When CUCM 7.1.2 is integrated with Unity Connection 7.1.2 by Skinny, MWI is notified by a StationMwiNotificationMessage message. A call triggered by the message won't tear down. If either version is older than 7.1.2, OffhookWithCpgn is used for MWI notification. As a result, this problem won't occur. Upon receiving SsInfoReq, MessageWaitingManager creates a new MessageWaiting instance with message interface type set to ON_NET_CMI. In this case, the MWI Activate APDU sent earlier is received. As a result, CallManager invokes clearCall to send SsClearCallReq to Cc. MessageWaiting rejects sending the SsClearCallReq if the message interface type set to ON_NET_CMI.
