Long time since I replied to a mailing this thread, lets hope I do this

                 /---> Phones
                /---> CCTV
BT -> Router --/--------\
                         >-- Router --> Internal Network
Virgin -> Router -------/

Your phones and CCTV could be on the other side, and it is probably
simplest to have them on one network or the other. I don't have much
experience with VOIP though. A switch will not do it, you'll need another
router and network behind the two BT / Virgin routers. Make sure the BT /
Virgin routers are on different subnets. There is probably some fancy
hardware out there that can roll all this into a single device.
