I have been using PIAF (nerdvittles) for my home PBX and I'd like to add home automation and MCE features to the system so I'm trying out LinuxMCE. I haven't figured out how to do the LinuxMCE equivalent of call groups with external phone numbers. In phone lines->settings I'm able to check the boxes for which extensions I want to ring, but I haven't been able to get a cell phone to be included there. I could set it all up in Advanced->Configuration->Phones setup, but if I set up a Ring Group in PIAF, I lose a lot of functionality like security system calls because it won't use the custom app.
Eventually the setup I want: incoming calls on line 1 rings all extensions in the house plus a cell phone where the cell phone is prompted to dial 1 to take the call. Incoming calls on line 2 ring only the office extensions and the cell phone, but the cell phone can take the call without dialing 1. This is how I have it set up in PIAF. Is any/all of this possible in LinuxMCE?
