We searched for a business phone system for an office of 30 plus. We had 3 different companies come out for a bid and Corporate Communications by far was the most knowledgeable, personable and overall gave us the best bid. The sales guy definitely knew what he was talking about compared to the other companies. The system was installed as planned with absolutely no problems. This is the best system we have had since we've been in business and could not be happier. Thank you!
