Well, I guess the magic of putting the _1NXXNXXXXXX exten in the local
context wouldn't be useful until you define an "untrusted" context:

[untrusted]
include => local

And, maybe, it'd be better to define the local this way instead:

[local]
exten => _NXXNXXXXXX,1,Playback(gojumpinthelake)
exten => _011.,1,Playback(gojumpinthelake)
exten => _NXXXXXX,1,Dial(...)


so, sip.conf might have
[lobbyphone]
context = untrusted

(all you want folks using the phone in the lobby for is dialing local
numbers) 

So, now, a single local context can serve both trusted and untrusted
situations.
The gojumpinthelake message will only get played when not overridden by
higher contexts.

It's backwards to what you are accustomed to, but still useful.
