I have my asterisk server in USA. and i want to be a DID provider, not the reseller from any other provider. i need to connect my server via T1/E1 line, after that i can sell the DID to my customers, and they can route the DID where they want.
I do not have much information about DID, so i am not sure T1/E1 connection can help us to be DID provider.
Please give me some information and some USA telecom web site, who can provide us these connection?
