Hi everyone.

In MT Call flow must be as below

    

MS                                                BTS

                  <- Setup

               Call Confirmed ->

         <- Assignment Command

          Assignment Completed ->

                   Alerting ->

                   Connect->

but in implemented code in mnccms.c file immediately after sending Call Confirmed message, Alerting message is sent from MS to BTS , and this lead to ignorance of Assignment Command from BTS. WHY the procedure implemented as this ???
