[Asterisk-Users] include behavior (word puzzle of the day)

[Hughes, Sam]

With that setup context2 is part of context1, which is a part of
context3, so yeah, you have no security.

 

What you need is something like this:

 

[context1]

;List your sip users here

 

[context2]

;Media gateway

 

[context3]

;Inbound calls start here

Include => context1

 

[context4]

;dialout context that allows trusted extensions to dial out as well as
call each other --start your sip phones here

Include => context1

Include => context2

In the example below context2 is included in context3 because it is
included in context1.

 

Is there a way to include context2 in context1, and context1 in
context3, but not context2 in context3 as a result.

 

[Context1]

;sip users with 10 digit extensions

Include => context2

 

[context2]

;media gateway terminating local 10 digit calls

 

[context3]

;inbound PRI via media gateway

Include => context1

 

I have a case where a dialplan is insecure because inbound calls in
context3 can be re-routed back out in context2. Actually, what occurs is
a loop, where the call comes in context3, finds no match in context1,
egresses in context2, and repeats the loop, setting up a lot of calls in
a short period of time!

 

Extensions in context1 need to be able to reach extensions in context2

 

Inbound calls into context3 need to be able to reach extensions in
context1

 

Inbound calls in context3 MUST be restricted from reaching extensions in
context2 which are outside extensions sent out to a SIP provider.

 

It would seem more logical and secure if includes did not cascade, or
would not make 2 "hops"

 

Perhaps I have failed to understand some simple concept that would
resolve this issue?
