Sip calls in one direction

Hello, i want to configure asterisk to accept incoming calls from a sip account that has insecure=port,invite . and host=XX.XX.XX.XX . at the same time, i want to use the same ip to make sip calls.

what happens is that since ive setup the outgoing calls to that ip, incoming sip calls are not associated with the sip account that has the insecure=port,invite … any idea why and how to work around it ?
