From the information above, we can find that Eudemon can forward the CRCX transmitted by Sx3000, but Eudemon fails to process the SDP of CRCX_RSP message of IAD, and it does not forward it to Sx3000. At the beginning, we thought that the version of Eudemon is problematic; after careful checkup, we find that the range of media interface is not configured. Add sbc portr media beg 30000 end 65535, and the problem is solved. For more debug information, see the attachment.
