We have it set up that when you make a call from our site to an outside site, the extension you are calling from is not displayed.  The only number being displayed is the operators extension.  We received messages from a group of users complaining that people(customers) are dialing their extensions directly because they claim their extension is the one that showed up on their caller id.

Is this a trunking issue or what?

More information is in order.

What types of trunks are the calls going out on?

Are you able to confirm that the problem that the users are complaining about is actually happening?

The calls are going out on an ISDN type trunk.  

Yes, I was able to confirm the complaints because I called one of the customers back and they informed me of how they got the number to call back.

Do a 'change isdn public-unknown-numbering' command and see if there isn't an NPA-NXX setup for the extensions of the users who made the complaint.

You can change it so that the group of extensions send only a single number.  Just change the CPN prefix to be the ten digit number of the attendant.

Test by having someone call a cell phone or something that can receive caller ID information.

You can also restrict sending CPN on a station by station basis.  On the second page of the station form, change the 'Per Station CPN - Send Calling Number?' to 'n', and it will not send the caller ID for that station.

There was nothing set up for the extensions  in the ISDN public numbering area, of the users who made the complaint.

If I change the CPN prefix, can I do it at one time?  Or do I have to do each extension individually?

On the CPN, by a sta. to sta. basis, is the blank and restrict option the same as the "no" option?

You only need to put the first 1 or 2 digits of the extension range that you would like to give a CPN prefix.

So you might put extensions that start with "21", 781-555 as a prefix.  The system will add 781-555 to any extension in the system and it will read 781-555-2100 (for example).

If you put an entire 10 digit number (781-555-1234 for example) in the CPN prefix, then any number that starts 21 would send only that whole number.  The extension isn't included.

Telemarketers do that to send the "do not call" call-back number to people they dial.
