<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">If an INFO arrives with no signal= line in the body, then we'll end up queuing a frame with 0-length DTMF. I have no idea what the result of this would be, but it's a good idea to make sure that the event is not '\0' before entering this if/else block.</pre>
