I'm a server guy and have been for quite a while. I have played around with a large PBX in the past, but this is new to me. Just started at a small hospital as the only IT guy and we have a CallPilot Mini 150. Our phone service is through AT&T, and I am able to get into the CallPilot Mini and make changes. However, I am not able to see where I can set up a new line or move extensions from one office to another. The large PBX I played with before had a separate system to administer the lines. All we have here is the 150 hanging on the wall and I can access it by navigating to its IP address. Completely new to this side of things and I know some of you are probably thinking I'm a complete idiot. We used a program at my last job to get into the system to make line changes (Not mailbox changes), but I can't remember what the name of it was or if that's even an option here. Can someone point me in the right direction? I'm completely lost. I'm fairly certain they have just called AT&T in the past to make changes, but I'd like to manage it myself if at all possible.
