Greg has created a network for his office, but Time Warner Cable is dragging its feet installing his phones. So, he's been looking into Clear Wi-Max via cell phone. Leo says that it works as long as he has a line of site to the base station.
Greg is also wondering about Ring Central. Leo says it's different because it's a SIP phone, which is designed to use the Internet. Leo recommends them and they do a great job. So dump the phone system from Time Warner Cable and get them to hurry up installing the Internet access. In fact, Leo suggests going with an independent like DSL Extreme. They could possibly get it done faster.
