  cd /var/lib/asterisk/agi-bin/

Creating .env

  nano .env

Copy the following content and add the APIS Key.

OPENAI_API_KEY = "sk-"

The format to record a prompt is as follows:
./record-prompt.py file-name "Text to record" language
file-name --> file name if extension mp3, remember that in the Agent AI script, the welcome audio is: welcome-en (English), welcome-es (Spanish), and the wait audio is: wait-en (English), and wait-es (Spanish).
languaje --> could be "en-US" or "es-ES"
If you want to add more languages, you must modify the scripts

Below we show an example of how you should use the script to record the prompt.

./record-prompt.py op_ai_welcome-en "I am your AI Operator, after hearing the tone, could you please tell me the name of the person or the area you wish to communicate with?" "en-US"
./record-prompt.py op_ai_wait-en "Wait a moment please." "en-US"
./record-prompt.py op_ai_transfer-en "Transferring your call, please hold." "en-US"
./record-prompt.py op_ai_short-message-en "Your message is too short, please try again." "en-US"
./record-prompt.py op_ai_user_not_found-en "I'm sorry, we were unable to find the information you requested. Please try again." "en-US"
./record-prompt.py op_ai_welcome-es "Soy su Operador de IA, despues de escuchar el tono, ¿podría decirme el nombre de la persona o el área con la que desea comunicarse?" "es-ES"
./record-prompt.py op_ai_wait-es "Espere un momento por favor." "es-ES"
./record-prompt.py op_ai_transfer-es "Transfiriendo su llamada, por favor espere." "es-ES"
./record-prompt.py op_ai_short-message-es "Tu mensaje es demasiado corto, inténtalo de nuevo." "es-ES"
./record-prompt.py op_ai_user_not_found-es "Lo sentimos, no pudimos encontrar la información que solicitaste. Inténtalo de nuevo." "es-ES"

Testing call from VitalPBX

Now call *885 for English or *886 for Spanish and ask to be connected or transfer to a person, department (sales, accounting, support, etc) or extension.
