Thanks for the response /Benny

My understanding is that the 'context=whatever' in sip.conf is the name 
of the context that handles incoming calls from the outside - that's 
what I meant by 'incoming'.

I'm quite clear that 'incoming' means calls coming in from the outside.

The 'insecure' part is that knowlegable callers _could_ call in and use 
various methods to make outside possibly expensive calls _if_ the 
outgoing extens were in the same context.  I don't want that!

That's why I want a clear separation between the incoming calls from 
outside and calls to the outside made by my phones on the inside.

The problem is I don't know how to use a context in extensions.conf 
without referring to it in sip.conf (context=something).

Do you know of a way?
