Noob question: inward numbers vs extensions 1

[MikeSayers]

I'm a total noob on this system, just hired and inherited from a guy who's gone. Between the documentation and sites like this one, I have the console down good enough to get by.

Here's my question: Extensions are dialable from outside; for example calling 321-2222 from elsewhere will ring on extension 2222. But we have two exchanges, and some extensions are on one exchange and some on the other. Is there any way to tell which exchange a given extension is on? For example, whether 2222 is 321-2222 or 329-2222.

If 2222 is your DN then either exchange will work if your carrier is sending 4 digits. If you only have 2222 in one of the DID ranges I would call 321 2222 and 329 2222 and see which one rings your phone.

I have the same situation. Here is a suggestion, IF your site uses CLID tables as mine does, and is passing the caller ID i.e.. (XXX)321-2222, (XXX)329-2222 there SHOULD be a CLID assignment for both exchanges.
Print the TN of the set(s)

DNDR 0
KEY 00 SCR 6836 0 The 0 is the default CLID entry in my table for my (XXX)957-6836 DID
01 SCR 2999 1 1 is the entry for the second exchange (XXX)991-2999
CPND
NAME Data, Center
XPLN 27
DISPLAY_FMT FIRST,LAST

zstic78, that's it! Thanks. Turns out there's 3 exchanges.

This information is what you program in the PBX to show the correct number when you dial out to another number. they will then see the correct number come up in their display.
The only way to know what DID ranges are coming in to your PBX is to talk to the local Telco, who will tell you exactly what NPA/NXX your numbers are using. They typically send in 4 digits on older systems, so you would have no way of being able to separate the numbers for each range, which could be confusing if the ranges are somewhat close to each other.
You should make note of your ranges for when you have to assign a new number to a phone in the future.

If you print your cdb

>ld 21
PT1000

REQ: prt
TYPE: cdb
CUST 0


and look for the LDN0 entry - that *might* give you a clue as to how many digits the telco's are sending you - the length of the DN in that field is how many digits that are read for DID lengths.**

** as least that's what I remember!

Thanks guys! I found the documentation of the DID ranges. Yes, our site uses CLID tables. I learned how they work, and cleaned up a few extensions that were IDing incorrectly (ENTRY # was wrong). All is good.
