title: Talking to a KX-NCP1000 PABX
body: <p>I can establish a TCP connection to the PABX. It prompts and I can log in, and receive a few call records. But after not very long the PABX drops the connection for no reason I can fathom. It's definitely getting ACKs, I checked with Wireshark.</p>
  
  <p>In <a href="https://stackoverflow.com/questions/8382535">this related question</a> CharlesO says</p>
  
  <blockquote>
    <p>You simply write a TCP Listener to accept connection from the PBX and
    parse the incoming Call Detail Records (CDR).</p>
    
    <p>Have done this successfully with Avaya, Panasonic and other PABX
    Products</p>

  <p>Does this mean the problem is simply that the design is "don't call us, we'll call you" ?</p>
