I have just stepped into a company with a definity system.  When a call is made to a person/company with caller id, our PRI line number appears(when they call back they get a not in service recording).  How can I program our main company number to appear?


I don't understant a problem to call back? Who gets recording, somebody at your office
when he makes outgoing call or not?
I think you should check form:
change isdn public-unknown
where you may enter calling numbers for your switch extensions,
which will appear on display of the called party on other end of PRI line.
On first page of trunk group form (if isdn-pri trunk used) you can delete all
digits from incoming call ID and insert  new ANI-preffix.
On the second page of trunk group form you may chouse to send calling number
or not outgoing calls. The same options must be available on other end of PRI line.



Let me clarify.  When a person we call that has a caller id phone uses that phone to call us back, thier phone displays the number associated with our pri line.  Consequently it does not ring to a real phone number.  What I need to do, is program the system to display our main number so when a person sees a number displayed from our company, the main line number will appear.  I am looking for what to change within the switch menu options.  Thanks!


It sounds like Dimas is saying you can adjust the outgoing ANI on the second page of your isdn trunk form or at least turn it off.  I can't verify as I don't use isdn but do a cha tru x where x is your outgoing isdn trunk group, look at the second page and see if there is y/n flag to stop outgoing ANI.  If this is so it will at least stop people from calling the wrong number until you can find out if there's a way to adjust the number to your LDN.


Use the "change isdn public" table on the pbx.  The first item is the extension length, then extension range (closest match counts, like ARS), what you want to prepend the extension with, and then the CPN length.  For example if you have extensions start with 22xx you woul make the entries as follows:
Ext ext-code  cpn-prefix   cpn-length
4     4         212-832       10
4     221       212-833       10

The above would send 21283222xx for any call sent from an extension start with 4.  It would send 212833221X for any call send from an extension starting with 221X.  The provider of the ISDN can also an ANI number by befault so this may come into play also.

Hope this helps



2 steps:
1.)  make sure local company that pri line is service through has correct default ani information.  
2.)  as someone already mentioned:  change isdn public-unknown this is used to send ani number for specified extension range.  However as I have found out if your switch is integrated with older or other brand switches it may not receive extension information so it will send call out and local carrier's default will be used.  In our case QWest had an incorrect number in their database.


I would just set up the change isdn public number to send the main business number then anyone could call in and get to the auto attendand etc. If you want the main isdn number to ring you would need an auto attendant. Also on each station you will need to chack the box that says send calling number.
