Hi All

There are many examples in the T.38 FAX protocal SDP and callflow.
I couldn't find anywhere T.30 FAX protocal SDP example and callflow. 

1. Should  the T.30 FAX protocal callflow controled by MGC ?
    In the draft-ietf-megaco-h248f-01.txt , that is ambiguity,  I think

2. if MGC must control T.30 FAX callflow, Audit Command will be sent  to MGs by MGC
   How Could MGC structure command ?     which commands are right ? eg1 or eg2 ?

   eg1)
   MEGACO/1 [207.176.47.89]: 27000
   Transaction = 1234 {
       Context = 1  {
           AuditValue= aaln0000{Audit {Media} }
          }
   }

   eg2)
   MEGACO/1 [207.176.47.89]: 27000
   Transaction = 1234 {
       Context = * {
           AuditValue= ROOT {Audit {Media} }
          }
   }
   
3. How MGs could make that's reply ?  

Could you give me some advice ?

Thanks,
