This is a n8n Telegram Call In Workflow. It will wait for message from Telegram bot and sent to the Call Center to process. How it works - The Telegram Trigger node will wait for the message from the Telegram bot. - When message is received, it will first check for the matching Member from the PostgreSQL database. - Then determine if it is a Text message or Voice message. - For voice message, use the Google Speech to Text API to transcript it into text. - Finally, pass the text to the next flow, i.e. the Call Center.
