title: How to record phone call via DialUp modem
body: <p>I've tried <a href="http://www.concelsys.com/voice_modem_software_call_recorder_logger_apr.htm" rel="nofollow">this program</a> and It's compatible with each dial up modems connected to my laptop and I think it's using a windows API or a public API because the other programs I saw were only compatible with serial port modems but It's working with my USB modem</p>
  
  <p>Is there any compatible library in C# to record calls? </p>
