I'm looking for a developer to create a VoIP Auto Caller application for me. This application should be able to make calls to a specific list of Toll-free IVR numbers and navigate through the IVR system automatically to reach the Balance Enquiry step.

Key Features:

2. Capability to upload a plain text file with 1,000 to 10,000 account details for balance enquiry.
