I am experiencing an issue with my Vapi assistant, where it fails to store the callback number correctly provided by the caller. Most of the time, it adds the last two digits of the number again, resulting in an incorrect callback number. **Details**: - **Model**: GPT-4o Cluster - **Transcriber**: Deepgram Nova 2 (German) - **Voice**: Cartesia (German Woman) - **Field in Structured Data**: - **Name**: CallbackNumber - **Type**: String - **Description**: "The callback number of the customer who wants to get called back." **Relevant Part of the System Prompt**:

markdown
[Rückruf organisieren]
1. **Rückrufnummer**:  
   „Möchten Sie, dass wir Ihre Anrufernummer verwenden?“  
   - Falls nein: „Welche Nummer sollen wir stattdessen verwenden?“

Translation:

markdown
[Organizing Callback]
1. **Callback Number**:  
   "Would you like us to use your caller number?"  
   - If no: "Which number should we use instead?"

**Example**: If the user said a number like:

Zero One Two Three

The stored number would be

012323

I also attached two screenshots showcasing the error. Here is the translation for the number the caller stated:

Zero One Seven Six One Two Three Four Five Six

I have no clue what the cause could be. Maybe it's an issue with German transcription? https://cdn.discordapp.com/attachments/1295366678586196089/1295366678921875539/Screenshot_2024-10-14_at_14.40.17.png?ex=670e63bb&is=670d123b&hm=b3f3cab7c681edeb42381f9e75150615ffd278d25991a9d3a2d63bc9a9bf3da6& https://cdn.discordapp.com/attachments/1295366678586196089/1295366679198433311/Screenshot_2024-10-14_at_14.39.42.png?ex=670e63bb&is=670d123b&hm=c50ee243e7f0510ada806ca0ed1f082b5be558a45b298abe6de5abea5b48f2c1&

@nex try using this: Callback Number: "Would you like us to use your caller number?" - If no: "Could you please tell me the number you'd like us to use? Say it one character at a time, please." - "Let me confirm: The number you gave is [repeat the number, one character at a time]. Is that correct?"

Thank you for the suggestion! I’ll try it out and see how it works
