I use 2 buttons on my phone for setting my status to Out of Office and Available. Because, when we leave the building, the telephone needs to be forwarded to my cell phone. So, I have *30 and *31 (or *32) as speed-dial on my Grandstream phone. With my old ISDN phones, a red light was turned on when forwarding was on. Easy for my coworkers. I want this too on my Granfdstream phones. There's something like a BLF, but it only works when the phone is off-hook. I want the light to be red when the status is set to Out of Office, and then turn green when the status is back to Available, so anyone can see if forwarding is on (red BLF for Out of Office) or forwarding is off (green BLF for Available). Is this possible?
