[asterisk-dev] fix for domains with empty context

Andrey -
   Thank you for the patch!  However, chances are slim that it will 
find a way into the TRUNK of Asterisk unless you open a ticket in the 
Mantis bug tracker.  Also, if you have not signed a disclaimer, you 
will need to do that too.  Instructions can be found on 
http://bugs.digium.com/  - I know it sounds like a chore, but it's 
currently the best and only way to ensure that the patches are 
correctly reviewed and applied.
