Pix/Atto,
The flow goes like this:
CM Service Request (From Mobile)
Connection Confirm (From MSC)
Classmark Request (From MSC)
CM Service Accept (From MSC)
Classmark Update (From Mobile)
CM Service Abort (From Mobile)
Clear Command (From MSC)
Clear Complete (From Mobile)
Released (From MSC)
Ciphering is not used in my case.CM Service is accepted by MSC and then mobile aborts it with no cause.
There are lot of such call flows and no apparent reason is found.
Atto,
In which country are u using Astellia?
