Hi Guys, I have 12 cat5e ports on my office which are all wired into a patch panel. I want to use one port to run a normal bt phone so I purchased a cable off eBay which has a standard UK phone connection on one side and RJ45 on the other i simply put one side into my ADSL filter and other side into the patch panel. On the other end in the office I purchased a PABX master adapter which I plugged into the RJ45 and put my phone in but there's no dial tone! Any suggestions please? Thanks
