Its not only a security issue, its because the central office system can only handle a few requests at a time. I know first hand about having to wait to get in and there's only legitimate people using it.

As for any toll free numbers, somebody is paying for each call.

... You just gotta know who and how to ask. Explain your situation... "Hi I'm Joe Schmuck with XYZ Electricic doing some inside work for a customer at 123 Blahblahblah St. I need the binding post numbers for 415-123-4567?"

E57, that's pretty bad advice. You are not supposed to be in a telco terminal, that belongs to them. Its not a demarc or NID. I know you are going to say well, everything is run in there without a demarc and yes, that's true but any wiring is supposed to be run by the TELCO. I wouldn't be stupid and call repair or the business office and ask for binding post numbers if I were you. That's an admission if ever I heard one. At the least they can make you pay for damages and service interruptions and at worst they can press charges if you give them reason and its a federal offence.

Do it the right way and call for a locate and tag.
