We used these guys here in Houston, long story short, they did an awesome job. Turns out the tech(Cliff) and I are both from the same small town in Ohio too. The main guy is Chris. He took the time to answer all my questions that the other posers made me feel stupid for asking. Amazingly, he even showed up after the installation to insure I was happy. I did not know that still happened? I was so impressed I referred him to my next door neighbor and now we have matching phone systems. Just goes to prove, if you do a great job, good things happen.
