Flynn,

Yes, that makes sense. However, in my case I have incoming calls
arriving on an IAX channel from a PSTN gateway. I think the concept is
the same.

That said, if incoming calls have access to the internal context so they
can call internal extension doesn't that assume that hey have the
ability to dial outbound as well if internal context users can? This is
what my testing suggests unless I'm doing something wrong.

Thanks much!

Chad

Here's what I mean:

extensions.conf
===============[internal]
; define your internal ppl to this context
include => extensions
exten => _9.,1,Dial(Zap/1/${EXTEN:1})

zapata.conf
==========[channels]
; TDM40B card
signalling=fxo_ks
context=internal
channel => 1-4

iax.conf
=======[1000]
type=friend
context=internal
disallow=all
allow=gsm
host=dynamic
username=1000
secret=1000

so this meanas the four extensions plugged in to the TDM40B's all will
fall into 
the "internal" extension, as does the IAX user "1000". So if
you have
additional 
office staff at extensions "5001", "5002" and
"5003" connected via SIP,
in 
sip.conf you'd create those entries and set "context=internal" in
the
respective 
entries.

Hope this helps!

Flynn

Yes...Crystal.

Thanks Flynn

Technically they can, but it would depend on how you have your dialplan 
configured. Which is why I always separate the incoming lines and
internal lines 
into separate contexts.

A further example might help. Say your extensions.conf looked like:

[outgoing-calls]
exten => _9.,1,SetAccount(1000)
exten => _9.,2,Dial(Zap/1/${EXTEN:1},30)

[internal-extensions]
exten => 5000,1,Dial(IAX2/5000,30)   ; John Doe's extension
exten => 5001,1,Dial(SIP/5001,30)    ; Jane Doe's extension

[incoming]
include => internal-extensions
exten => s,1,Answer
exten => s,2,Background(welcome-message)
exten => i,1,Playback(invalid-option)
exten => i,2,Hangup

[internal]
include => outgoing-calls
include => internal-extensions
exten => 8500,1,VoicemailMain

And say you've defined the incoming lines to hit the "incoming"
context.
Here, 
they only have access to listen to the welcome message, and they can
only dial 
the numbers "5000" and "5001" which was included by virtue
of the

include => internal-extensions

directive. If they enter anything else, then it will fall into the "i"
extension, where the "invalid-option" message would play and proceed
to
hang up 
the call.

By the same token, your internal extensions are defined to hit the
"internal" 
context. Here, they can dial the numbers "5000", "5001",
"8500" as well
as (for 
example) "95555555555". They can dial "95555555555" by
virtue of the

include => outgoing-calls

directive, which is not present in the "inbound" context.

See the difference?

Hope this helps!
