DID Range Enumeration

I apologize if this is a double post, but my
connection was cut when I tried to send the first
time.

Does anyone know of a method to identify the DID
ranges assigned to a company? As part of a blind
pen-test I have been asked to complete a war dial, but
the company does not want to give me the ranges.

I would greatly appreciate any help.

Thanx
