[asterisk-users] Suggestion for a new asterisk setup.

[Andrew Joakimsen]

So, do the same setup with the DNS, setup a colocated machine and your
asterisk inside the LAN registers with it, in your dialplan instead of:

exten => 123,1,Dial(SIP/123,25,r)
exten => 123,2,VoiceMail(u123)

Do:

exten => 123,1,Dial(SIP/123,25,r)
exten => 123,2,Dial(IAX2/colocation-asterisk/${exten},r)
exten => 123,3,VoiceMail(u123)

And on the colocation don't do any sort of voicemail.

Since if you are inside the LAN the DNS would point to the asterisk in the
lan and outside it would point to the colocated machine, it should ease the
security concerns you have and also provide the same functionality, you can
plug in the phone anywhere and it will work just the same.

You will require some testing/tweaking however to insure every possible
senario works (IE: Calls between 2 phones conected to the colocation
asterisk)
