Here is a very very simple example using a PRI. You will need more error 
routing in a real dial plan:

extensions.conf:
[general]
static=yes
writeprotect=no
country=us

[local]
include => default

[globals]
TRUNK=Zap/g1
LDTRUNK=Zap/g2

[trunk]
;Long distance pstn
exten => _1NXXNXXXXXX,1,Dial(${LDTRUNK}/${EXTEN})
exten => _1NXXNXXXXXX,2,Hangup

;pstn
exten => _X.,1,Dial(${TRUNK}/${EXTEN})
exten => _X.,2,Hangup

[default-out]
;This is where you sent trusted calls from sip.conf out to pstn
include => trunk

[default]
;you send incoming pstn calls here as well as untrusted voip calls.
;here you would route call to local numbers you own via enum or static.
exten => 6153247060,1,Wait(2)   ; you need to wait
                                 ; long enough to get
                                 ; CNAM off line
;send incoming call to your register server.
exten => 5555554444,2,Dial(SIP/5555554444 at inside-voip.com)
