</div>That's not a problem with the TDM800 card... it's just a side-effect of<br>
analog signaling. For analog calls, the central office doesn't give any<br>
type of signal when the far end has answered the call, so Asterisk has<br>
no way of knowing when that happens. For that reason, Asterisk<br>
immediately treats any outgoing analog call as having been answered.<br>
