Can you get multiple phone socket working with BT ...

Question

Hi,
So I recently had a BT engineer visit, he connected the phone line on the main socket then left. A week later they turned my BT infinity on.
It works great but the main socket is in a different room to my office. I have a phone socket in my office right next ot my pc. But when i plug my router into this socket it fails to produce an internet connection. 
Is there a way to get multiple phone sockets working? I would like to move my hub so it is in my office but the socket isnt giving off internet.
Any help is much appreciated.
Thanks.

You need to identify the cables connected to the removable faceplate beside the red arrow - these are the extension cables to other sockets in the house. 
Connected from here you will get voice only - not data. 
If there is more than 1 cable you need to identify the one to your office, remove it and fit the cables to the yellow arrow connections. 
You only need to connect the cables connected to 2 & 5 (there may be more connected to the faceplate)
guide on this link  although it does not tell you the 2/5 connection order - I don't think polarity matters - but someone with more knowledge can advise. 
A potential problem you may have is if there are other extension sockets connected to your office socket you use (and not the faceplate) as these then are not suitable  for phone - only data. 
With DECT phones and the need for just one basestaion not really a probem nowadays but you need to know where each socket in your house is connected from, and what you want to use it for. 
If you have any BB problems, BT will also insits you plug the router/modem back into the master socket for all testing. 
EDited to add - a krone insertion tool is best for inserting the cables to the socket and has a nice pick to disconnect also. They are easy to use - search you tube for a video.
