@Amanda (Vapi) Hi! I have an issue with inbound BYO SIP Trunking. My carrier (Inbtel/PBXHosting, Sippy Softswitch) sends INVITEs from IP 207.182.145.2 to sip:526627760699@sip.vapi.ai:5060 but Vapi always responds 401 Unauthorized (Digest challenge). The carrier operates in IP-auth mode only and cannot respond to Digest challenges. What I already configured: BYO SIP Trunk credential, inboundEnabled=true SIP URI phone number The problem: Vapi still sends 401 Unauthorized on every inbound INVITE. I have a PCAP proving the traffic reaches Vapi correctly. org ID: c72786ec-d64f-4f80-a79a-c47f504a73c2 Can you help enable IP-auth (trusted peer, no Digest) for inbound INVITEs from 207.182.145.2 for this org?
