It would help greatly if you provided more detail about the exact actions that are involved, and which devices in the network are sending this messages to which devices. Also, it helps to spell correctly and use complete sentences. In your message, it's not clear what "MO" is. Also, sometimes messages are describes as "from User-B" and at other times, "from network". At what point in the network are we observing the message flow? In many situations in SIP, the standards allow the devices a great latitude in behavior. This is especially true when the question is whether a device should send CANCEL for an INVITE or a BYE -- in many situations, a user agent may reasonably decide that it can perform no useful communication, despite that it is participating in a valid SIP dialog, and thus send a BYE to terminate the dialog.
