If you are implying there are nat settings in the pjsip I couldnt find them in the GUI

PJSIP Trunk for FXO Behind Nat General Help

You mean these settings in the Advanced tab under PJSIP settings in the trunk? Which, BTW, are set to “yes” as their default. [2019-10-12%2012_02_58-Window] You need to describe this issue a bit better. Which side is getting the one-way audio? Who can’t hear who? Where is this FXO device compared to the PBX? Etc. etc. etc…
