Sorry about comming in on this so late but I was gone for the week-end. We do hotels all over the county and Hal is right check the local code, that is what you have to go by. It changes from time to time and we have to go and make changes to the elevator phones. We also have to get with the elevator company because many of the elevator phones are programmed to dial out when picked-up. Most locations in North Carolina require C.O. dial tone and cannot go through the PBX. What city and state are we talking about, we may have a hotel there and know what is allowed.
