Actually, I think this behavior makes perfect sense.  Every channel API 
call in Asterisk behaves this way.  This API call assumes the channel to 
be up, because it's hard to read digits from a channel that isn't up. 
:-)  API calls that have this requirement all return -1 as soon as 
possible to indicate that the call has been hung up, and that the 
appropriate post-hangup cleanup procedures should be done now.
