fix: add call ID check in error_handler method

- Add a check at the beginning of the error_handler method to ensure
  it only processes messages for the current call.
- This prevents processing errors for unrelated calls, improving the
  reliability and correctness of error handling in the SIP call.
- The change aligns the error_handler with the message_handler, which
  already had this check in place.
