The project `twiSQL` is a set of SQL user-defined functions that enable telephone calls and text messaging from TSQL code using Twilio's services. It includes two main components: `msgTwilioMakeCall` to place phone calls and `msgTwilioViewCall` to view the details of a specific call. The project also demonstrates how to create tables to hold prospect information, insert records into these tables, and then loop through these records to make telephone calls using Twilio's services. Additionally, it shows how to check the status of completed calls by retrieving the XML response from `msgTwilioViewCall`. The code can be used as a starting point for building a complete call campaign system with minimal expense.
