First of all, it crashes when creating a Dedicated Bearer on the default Session that is created for the first time. This behavior should be possible, so the related ASSERT is removed. Next, the InitialContextRequest is modified during the Attach Request to include the first Bearer. Finally, there was an issue where trying to create a Dedicated Bearer with SGsAP enabled resulted in an InitialContextSetupRequest message with a PTI of zero. This is because MME initializes the PTI to 0 upon receiving the Create Bearer Request while processing SGsAP. All of these issues has been fixed.
