Hi there. I hope somebody out there can help me.

My company moved into a new office a couple months ago. Here I found a small closet under the stairs, and there, an old but not that battered Panasonic PBX. I managed to bring it to life again, and after a couple calls to the landlord, we found that the PBX was abandoned. So I say, "let's  use it!" and proceeded to wire the office. I managed to wire 20 extensions, and I even found a second-hand KX-T7730 programming phone in a flea market (2 bucks!).

I found the manual on the 'net and I've programmed all I can understand what does it do. So my own extension is 321 instead of 113, I have connected a radio to the background music, and if I go out I can route my extension to my cell phone, just to name a few. It has been working flawlessly for a month, as far as I know.

However, I have problems. I'm pretty sure I've missed something when I installed the system, because when any of my outlines ring, all the extensions rings too. I know (because in an old job of mine we had a PBX just like this one) that there is a way to force all the incoming calls to route to the operator extension, and then the operator may hang up or forward the call to another extension. I assume it is something related to the extension group or the trunk group setup, but all I can do now messign with those settings is route all calls to the operator and then nobody can answer them nor make calls. I'm not sure why.

Any ideas?
