I want to know if can set up SUA or M3UA connection between two ITP? If ITP can act as SCTP client behaviour?
Could someone confirm to me.
If the MSC supports server mode m3ua its possible this will work. The PGW is in client mode and relies on ITP in server mode. If you remove the ITP, the MSC would have to behave similar to the ITP.
You are correct. ITP only acts in server mode for both M3UA and SUA.
