However, I have not been able to figure out or find the documentation on  how to direct sip calls made to just foo.bar to be sent to a default extension. In the sip debug it says its looking for the IP address of the caller in the default context which of course it cant find and rejects the call. Is there a way to force the extension?

I'm trying to do the same thing, but for invalid numbers. If someone 
calls an invalid extension, I'd like to send them to a menu selection. I 
have:
exten => i,1,Goto(mainmenu,s,1)  at the end of  the context called 
[default], but it doesn't do anything. I'm still reading and trying to 
figure out how to trace the call.
