### Answer If you're experiencing issues with the transfer number not saving correctly in the Transfer Call tool, here are the key troubleshooting steps based on documented issues: [(1) ]() Check for common formatting issues: 1. Ensure no trailing spaces - Verify there are no spaces at the start or end of the phone number string [(1) ]() [(2) ]() 2. Use proper E.164 format - The number should include the country code (e.g., +13473770030) [(3) ]() [(1) ]() 3. Include required fields - Make sure the

transfer_option

field is included in your transfer call configuration [(1) ]() If using the API to create agents: When creating a transfer call tool via API, ensure you're including all required fields. A missing

transfer_option

field has been known to cause the system to not save the number correctly, even though the API doesn't reject the request. Configuration steps in the dashboard: [(3) ]() 1. Click "+ Add" in the tools section and select "Transfer Call" 2. Set the transfer number in E.164 format or as a SIP URI (e.g.,

sip:username@domain

) 3. Configure the transfer type (cold transfer, warm transfer, or agentic warm transfer) 4. Save your changes Additional troubleshooting: [(2) ]() - Test on an actual phone call rather than webcall, as transfer functionality doesn't work on webcalls - Ver

ify your telephony provider supports the transfer operation [(4) ]() - Check your call logs for specific error messages If you're still experiencing issues after checking these items, please share your agent ID and whether you're configuring via dashboard or API so we can provide more specific guidance.

@AI Evy The website UI is not working properly. How do I file a support ticket?

### Answer I don't have specific information about filing support tickets in the available sources. For support with UI issues or other technical problems, I recommend: - Visit the [Documentation]() for troubleshooting guides - Visit [Hire certified Retell partner]() for professional assistance If you'd like, I can try to provide a general answer based on my knowledge instead.
