You must force the remote peer to initiate BGP-session. Then in error message
you see AS-number wich expect from you.
To achieve this try to apply outbound access-list to interface directed to
remote peer
access-list 150 deny ip host BGP_IP_ORIGIN host BGP_IP_PEER eq bgp
access-list 150 permit ip any any
