I'm sorry to hear that you're experiencing issues with calling. There could be several reasons why your calls are being disconnected immediately, including temporary service disruptions, configuration issues, or network problems. To assist you better, could you please provide me with more details about the issue? For example, are you receiving any error messages, or is there a specific pattern to when the calls are being disconnected? This information will help me troubleshoot the problem more effectively.
