No Stun if the UA is registering directly to sipx and sipx is anchoring media (in other words, unless a SBC or other software is managing remote users, no changes to the UA should be in place). UA needs to send internal ip address, no stun or nat, sipxrelay does that.
ONLY need to use STUN on sipx if the DNS SRV records do not point to the elastic IP (or you failed to configure with one). Ideally, Elastic IP is configured on EC2 and DNS SRV point to it for the UA. Your "secret high port" can be configured via DNS also as the SRV record. Media is on different ports, but realize xlite is very limited and no MOH, etc. is supported by the MFR. You have not provided a description really of what "doesn't" work in particular.
