Configuration**:
json
{
"function": {
"name": "transferCall",
"parameters": {

3. **Verify Destination Numbers**: Ensure numbers are in E.164 format (e.g., +15558675309) and can receive calls [source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1330632225612702725).
4. **Check SIP Settings**: Ensure your system is configured to handle SIP REFER messages properly [source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1332445611680372739).
5. **Review Assistant Logic**: Make sure your assistant's prompts and logic correctly trigger the transfer functions [source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1330658574491008001).
