[Kamailio-Users] BYE to the wrong IP

I need some hints as to what can be going on; Running: openser-1.2.2-tls Mobile 1 à PSTN à Provider SER à Local SER à Asterisk (Callforward) à Provider SER à PSTN à Mobile 2 When Mobile 2 hangs up, Mobile 1 does not get disconnected but hangs with dead air. Provider SER: Is load balanced using standards DNS round robin with one CNAME pointing to two IP's Our BYE goes to the wrong IP even though we use; modparam( "rr", "enable_full_lr", 1 ) ... fix_nated_contact(); force_rport(); if ( ! search( "^Content-Length:\ 0" ) ) { fix_nated_sdp( "3" ); }; t_on_reply( "1" ); record_route(); if ( loose_route() ) { route( 1 ); break; }; I have tested with check_via = yes to no avail. Do any of you have any idea what might be causing this? I know the provided information is sparse but thought I'd try the short descriptions of the problem first, if it's a known miss config.
