[SR-Users] Re: Locally generated BYE sent to private IP

Hi all, I'm doing some experimenting with kamailio -- currently looking for a replacement of our existing (aging) SIP infrastructure. One of the experiments that I'm doing is testing the dialog module's dlg_set_timeout function. The issue that I'm having is while I do see that kamailio is generating a BYE, and sends it out to the B-leg of the call properly, the BYE goes to a private address on the A-leg. To Note: - kamailio is behind a NAT (on AWS) - both UA endpoints are remote and are both behind a NAT - Not sure if this matters, but I do have the topos module enabled, though I see the same behavior regardless if it's enabled or not. - Have set nathelpers (fix_nated_register, fix_nated_contact,etc...) which helps calls between endpoints and the endpoints themselves are able to send/receive BYEs when they generate them; however doesn't seem to help if kamailio locally generates the BYE. The only thing I do see within my logs is when the BYE is being generated by kamailio, it uses the private IP of my UA and not public for the caller. Callee, the public address is referenced. If more information is needed, please let me know (just didn't want to spam my script/ logs). Thanks.
