Any one here who has done SIP trunk integration with FreePBX? We are running into issues with Inbound calling on FreePBX. We are unable to detect the trunk URI on FreePBX. We are passing this URI "PJSIP/sip:your_unique_user_name@sip.vapi.ai" (we need to append PJSIP/ for freePBX to recognise the uri). We are getting error - unable to find end point "sip.vapi.ai". PS - we are able to make outbound calls. Its the inbound rhat is troubling us.
