So we have two possibilities:
1. Let the user handle this by explicitly making an empty context in 
extensions.conf and specify this empty context in the relevant "trunk" 

2. make the "trunk" option direction=[in|out|both] where:
   "out": all incoming requests gets rejected with 403
   "in":  all Dial(SIP/trunkname) attempts will cause
          immediate CHANUNAVAIL
   "both": allows both directions
