How can you tell which are DIDs?

[Bernie001]

Because of poor documentation on my behalf, I can't remember what the range is. I have three different blocks of DID:
3600-3699 we are using most
2200-2220 we are using a couple
xxxx-xxxx no are being used

How can you if you have a DID block in a list of unused DN?
I go into LD 20 and print the unused DN, there are too many.

Easiet way to determain what DID's your Lec provided you is to contact them. They will glady send you an email with your actual DID range. then you can do an ludn and look for the ranges that they sent you.

There is no way to tell by printing your LUDN without the CO's input on it. The PBX will tell you everything, DID or not.

another fast way if you have access is the good old phone bill.. normally they have the range right next to a price tag.. as stated, that is not in the switch anywhere
