more exten lines to dial your phones here

It shouldn't be insecure. It is perhaps a bit unusual to have calls
coming from your own phones labeled "incoming". That is probably the
source of the confusion.

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?
Larry
