We all have to start out as newbies. Learning by doing, and actually understanding how and why things work, is critical. You need to go to the Google Voice help pages and learn how the service works. You need to go to your Callcentric website and click through all the options, look at what they actually do, and refer to Callentric' FAQs. Otherwise, you just get told things to do, rote, and never learn. It's inconsiderate to keep asking the very most basic questions without making an effort yourself. We can keep answering questions ad nauseum, but understand that if you wanted an idiot-proof, turnkey solution, you'd subscribe to phone service from a full-service carrier. You get what you pay for.
