Hi there,

         I have a question for you, people. Suppose, I have a SG and a MGC that have to communicate
with each other. ASP #1 is attached to AS #1 and ASP #2 is attached to AS #2. Suppose both ASP's are
in the active state. I know the sctp association is a half-duplex channel, rigth? So, is it rigth for 
them to use the same IP:Port address to send and receive M2UA messages. Example, for ASP #1 in the 
SG the 65.198.40.50:3005 (IP:Port) address is used, and in the MGC the 65.198.40.52:3006 is used.

If that is the case, how is the communication synchronized?

|----------- SG -------------------||----------- MGC ---------------------|

ASP #1 ---- 65.198.40.50:3005 <-----------> 65.198.40.52:3006 ----- ASP #1

ASP #2 ---- 65.198.40.51:3005 <-----------> 65.198.40.53:3006 ----- ASP #2

Another question, can a SG support both, dynamic and static registration, of ASP's. I mean, to have
initially pre-configured ASP's and to support dynamic registration at the same time.

                  thanks,
                          Miguel.
