Confused about caller ID

[jp61616]

On our local calls here in town, the name of the school and switchboard number shows up on caller ID. For long distance, it shows up no name no number. From a previous post, someone told me to contact the LD carrier and see if they could put a static CPN on the trunk group so the LD calls do the same thing as the local calls. Is this all I have to do, or do I have to program something in the switch? This is what I have now:
>ld 21
PT1000

REQ: prt
TYPE: clid
CUST 0
SIZE 256
RNGE

INTL

ENTRY 0
HNTN 309
ESA_HLCL 467
ESA_INHN YES
ESA_APDN YES
HLCL 467
DIDN YES
HLOC
LSC

not sure what all this means but it was this way when I took over the phone system.

that is setup to show your did of each exten on clid table zero.. it's not working because the provider has to look at that field... because your clid does not reflect the clid table.. your provider is putting your main number on the call.. your ld provider can do the same thing.. you can send a number BUT unless each of your providers uses that field, nothing will change

Is your long distance route a 'plain' T1 (wink/ground start with DTMF) or PRI (23b+D)?

I think I made the other post you were referring to, and as I stated I assumed the LD route was a 'plain' T1. With plain T1's the only thing the PBX controlls is the dialled number. If it is PRI, then the PBX clid table _can_ change the CLID, depending on the restrictions of the carrier's switch that you are connecting through.

OK, I'm still confused. We have about 600 extensions running through our pbx. If we want the caller ID to say:
xyz college
309-467-(main switchboard number)

then the provider can do that?

But if we want it to say
xyz college
309-467-(extension number)

Then I have to build a clid table of all the extensions? How would I do that? And is that even necessary? Do big companies actually show the exact extension calling plus the name of the company? So you would know that not only is xyz company calling but it is bob at extension 5445?

This is all new to me so I appreciate your help.

If your trunks are PRI then 'one number (main bill) vs DID' is under the controll of the PBX (generally). If you have 'plain' T1's or analog trunks, then CallerID is under the control over the carrier, either local for 'local' trunks, or LD for LD trunks (assuming you have separate).

If you have PRI trunks, and if your CLID tables are set up correctly as John has suggested, and if your carrier allows you to transmit something other than your main number (configurable at the CO), then yes, you can transmit a specific DID number for every call.

The name is not stored in the PBX, the name is in telco records of whatever telco you get your DID's from. In the US, name is 'retrieved' from the far end by the _receiving_ carrier using a database lookup. Typically the 'name' on a business account is the same for all lines on the account, and is the business name (xyz college).

Verizon and SBC aren't playing nice in Kansas City, so for example, if I call from my office in Pennsylvania to my uncle in KC (verizon residential to SBC residential), he gets my number because the number is sent 'forward' with the call, but he gets 'pennsylvania call' because SBC won't pay Verizon to lookup my name.

I honestly think what you need to do is call your LD carrier and tell them you want a static calling party number of xxx-xxx-xxxx on your long distance T1, and that number is your main switchboard number. They shouldn't argue.

I used to manage telephone services for multiple colleges and universities in a former job, so if you need help, just post here for me to call you: don't post your phone number or email. I think I know where you are.

If someone really wants to go to the 'extension' level for transmitting CallerID, then you have to have PRI trunks for all routes, have the CLID tables built correctly (don't forget to have excpetions for the president, dept heads, etc) and then work with the carriers to make sure their screening tables allow you to send your own CallerID. In some cases PRI is cheaper than other trunk types, but that varies from carrier to carrier and market by market, unfortuantely.

Thanks, I think I understand now. I will call the LD carrier and I think that should fix it. Thanks for the responses - I appreciate it.
