Hi all,
I have a customer which has a PABX with some analog phone which is connected to the PSTN using an E1 connection. This PABX does not provide a call privilege mechanism so every analog phone can dial any PSTN extension. I am wondering if the insertion of a Cisco Router between his PABX and the PSTN : PABX <-------E1---------> Router <--------E1--------> PSTN will provide the call privileges using the corlist capabilities of the router.
Is it possible to do so?
Best Regards,
Hatem Hamdi,

Hi,
How do you want to implemet PSTN call access? is it by user or by phone?
If it is by phone, does the phones has Caller ID feature enabled? If yes, you can just use call blocking via voice translation rule command, then apply it on the outgoing dial-peer on the router.
If it is by user, what is the digit string dialed by the users in order to make PSTN calls? ex. 9XXXXXXX
Is it possible to modify the access code 9 to any mulitple digits? If yes, Access code will serve as a pin code and just make some translation rules on the router in order to strip the access code and send only the pstn number. pincode will only provided to authorized users.
Hope this helps,

Hi Hatem,
just to add to Paul suggestion
if the calls coming from the PABX to the router with the calling number of each phone enabled then you could do some digit manipulation to allow or block the calls
for example of you have internal extenstion number 1000 allowed to dial international calls and 1001 is not allowed you can creat inbound voip dialpeers per number of the above extentions ( calling ID ) to do digit manipulation
let
you can match the calling number by using the command answer-address follwoed by the calling ID
once you have this dial-peer aply a block voice-translation rule for the dialed number of internation dailing in the dial-peer that match the calling ID of 1001 while in the one for the 1000 just leave to go to PSTN
