Thanks dagwoodsystems. I'm still waiting to receive the exact wording of the glare error message being provided from his PBX. Once he provides this to me, we can hopefully cross-reference the message to identify the exact problem. I'm afraid to start guessing at this point, because I'm not very familiar with Definitys. I think the other tech whom was supposed to contact me has decided to hold off until the primary tech I normally work with returns next week.
