The two jacks on the x100p card are hard wired together, and you have no 
control over what might be perceived as fxs verses fxo jacks.

With that card, your only choice is to use one jack to connect to the 
pstn line and nothing else. If there is any other connection, asterisk 
won't know about it and really can't control it.

If a 911 call is truly processed by the asterisk dialplan, then you can 
configure asterisk to drop an existing call to process the 911 call. 
However, if there are multiple asterisk users, how do you know whether 
an existing call is also a 911 call? You probably don't want to drop an 
existing 911 call only to process another 911 call.
