Missing inbound SIP trunking / DID routing – need ...

Hi team, My workspace tj.prospects@gmail.com is missing the inbound SIP trunking feature. I can configure trunks and outbound SIP works, but inbound DID mapping is not available. My SIP Trunk configuration page only shows: Gateways Authentication Advanced settings There is NO section for: Inbound Numbers / Add DID Number-to-trunk mapping As a result, my BYO SIP phone number imports as byo-phone-number and cannot be linked to a trunk or to an assistant. Can you please enable the following feature flags on my workspace: sip_trunk_inbound_numbers enable_did_mapping byo_sip_number_routing sip_provider_mode

To associate your BYO SIP phone number with a SIP trunk in Vapi, use the following API call (replace placeholders with your actual values):
Copy code
bash
curl -X POST "https://api.vapi.ai/phone-number" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_VAPI_PRIVATE_KEY" \
  -d '{
    "provider": "byo-phone-number",
    "name": "Your DID Name",
    "number": "YOUR_DID_NUMBER",
    "numberE164CheckEnabled": false,
    "credentialId": "YOUR_CREDENTIAL_ID"
  }'
This links your DID to the SIP trunk credential. If the inbound mapping section is still missing, please contact support to confirm feature availability in your workspace.
