Just guessing but look for something like this..... 
This is from an old config of mine...
 
[trunkint] 
; 
; International long distance through trunk 
; 
exten => _9011.,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}}) 
exten => _9011.,2,Congestion 
 
[trunkld] 
; 
; Long distance context accessed through trunk 
; 
exten => _91NXXNXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}}) 
exten => _91NXXNXXXXXX,2,Congestion 
 
[trunklocal] 
; 
; Local seven-digit dialing accessed through trunk interface 
;
exten => _9XXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _9XXXXXXX,2,Congestion
 
exten => _9480NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _9480NXXXXXX,2,Congestion
 
exten => _9602NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _9602NXXXXXX,2,Congestion
 
exten => _9623NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _9623NXXXXXX,2,Congestion
 
[trunktollfree] 
; 
; Long distance context accessed through trunk interface 
; 
exten => _91800NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}}) 
exten => _91800NXXXXXX,2,Congestion 
exten => _91888NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}}) 
exten => _91888NXXXXXX,2,Congestion 
exten => _91877NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}}) 
exten => _91877NXXXXXX,2,Congestion 
exten => _91866NXXXXXX,1,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}}) 
exten => _91866NXXXXXX,2,Congestion 
 
[tofwdiax]
exten => _7.,1,SetCallerId,${FWDCIDNAME} 
exten =>
_7.,2,Dial(IAX2/${FWDNUMBER}:${FWDPASSWORD}@iax2.fwdnet.net/${EXTEN:3},6
0,r)
exten => _7.,3,Congestion
 
Note that I had a context for _9XXXXXXX
 
That meant if 9 and some nubmer dial my variables there...
 
Check the WiKi at www.voip-info.org and you can see more on Dial Plan

Subject: [Asterisk-Users] dial plan
I have just inherited a Asterisk box which is configured as follows.
 
10 internal Sip Phones 
 
3 Pots Lines
 
1 voip provider (SIP)
 
Call come in over the pots lines however Outbound goes out thru the VOIP
provider.
However looking at the configs I cannot figure out what controls how
call are sent out.
In other words where in the config files does it determine that all
outbound 
calls go to the VoIP provider?
 
 
Thanks in advance.
Mike
