Shouldn't filter on callerID since you can spoof it :)

You could use the ${CALLERID} variable to filter on.  Perhaps with a
GotoIf statement.  Have it send to another context and then use the
Authorize application to authenticate the call.

I just set that up as well the other day.  Here is what has worked for
me so far.  I'm sure there are far more elegant solutions, but it
works.  I'll tweak it as I go :)

[gateway]
; allow dialing out to the PSTN if the person authenticates
exten => s,1,Authenticate(123456789)
exten => s,2,Playback(pin-number-accepted)
exten => s,3,ResponseTimeout(60)
exten => s,4,Playback(this-call-may-be) ; This call may be recorded
because we're paranoid
exten => s,5,Playback(recorded)
exten => s,6,Playback(because-paranoid)
exten => s,7,Wait(1)
exten => s,8,Background(enter-phone-number10) ; Please enter your
ten-digit telephone
                                              ; number, area code first.
exten => _NXXNXXXXXX,1,Playback(pls-hold-while-try)
exten => _NXXNXXXXXX,2,NoOp("${DATETIME}:  Placing call to ${EXTEN}
via GATEWAY") ; CLI log message
exten => _NXXNXXXXXX,3,Dial(${LDTRUNK}/1${EXTEN},45)
exten => _NXXNXXXXXX,4,Hangup

exten => t,1,Playback(goodbye)
exten => t,2,Hangup

exten => i,1,Playback(invalid)
exten => i,2,Goto(gateway,s,8)

Thanks,
