PJSIP Warning in CLI

Greetings community members. I have a couple sip trunks and pjsip trunks. I keeping noticing in my cli some warnings from pjsip. Not sure if to ignore them or how to fix them so they don’t show up. I have 2 pjsip trunks via Grandstream gateway 1001 and 1002. I see warnings such as res_pjsip_registrar.c:723 registrar_on_rx_request: AOR ‘1001’ has no configured max_contacts. Endpoint ‘1001’ unable to register. I can place and receive calls on these trunks. Another warning is res_pjsip_registrar.c:678 find_registrar_aor: AOR ‘1002’ not found for endpoint ‘1001’.

Can anybody help me with these warnings?
