It is possible that this could be done, keeping the hub in its current location without necessarily running wires through the house.
What we need to do is somehow, plug a cable between the hub and the phone, keeping both in the same location. Well, your phone is connected to a wall socket, and from there a phone wire runs out to the Omnibox on your outside wall. At the same time, a larger coax cable runs from this box to the hub to provide internet connectivity. So imagine that the tech, runs a length of phone wire from the hub, uses the same hole in the wall (if possible) to push it outside and then follow the existing route of the coax down to the Omnibox. Disconnect the phone feed from the outside and spice the two cables together?
Effectively then you do have a single connection from the existing phone, via it’s wall socket to the hub, admittedly by a roundabout route, but this will work.
The problem will be whether whoever turns up is prepared to do this or be aware that this is a viable solution. At most they may have to enlarge the existing hole on the wall to run a phone wire through it and then re-seal it, but that has to be easier than drilling all new holes to move the hub, or run phone wire internally.
