Application Status - Your branded call application needs to be approved, which typically takes 1-2 weeks [(1) ]() . Check if your application is still pending. 2. Verified Phone Number - Without a verified phone number, calls may be marked as "Spam Likely" . Retell strongly recommends enabling verified caller ID to ensure your business name displays correctly . 3. SIP Trunk Configuration (if using imported Twilio numbers) - Based on a similar case, the issue could be [(2) ]() : - Caller ID isn't set to the actual Twilio number in your trunk config - The number isn't verified in Twilio - SIP trunk is passing internal or masked numbers instead of your Twilio number To Create a Support Ticket, Include: - Phone number experiencing the issue (in E.164 format) - Application status - Is your branded call application approved? - Number type - Retell-purchased or imported via SIP trunk? - If imported: Telephony provider (Twilio/Telnyx/Vonage) - Sample call IDs where branded calling didn't appear - Verified phone status - Is the number also registered as a verified phone? Quick Checks: - Branded caller ID is currently only available for U.S. numbers on T-Mobile, AT&T, and Verizon [(1) ]() [(3) ]() - If using SIP trunk, ensure the From header is set to your Twilio number in E.164 format [(2) ]()
