I can definitely help you get this working! The "bring your own number" setup with SIP trunks can be tricky there are usually specific settings for the SIP URI, authentication credentials, and inbound routing that need to match exactly between Vapi and voip.ms. Since this requires some back-and-forth troubleshooting and testing to diagnose the exact configuration issue, I'd be happy to work with you directly on this. I can walk you through the proper setup, test the connection, and get your voice AI running smoothly. Would you be open to discussing this privately? I can provide hands-on assistance to get this resolved quickly.
