Re: "previous tenant had taken the wiring with them"
Had to arrange the installation of a phone line at a building we were using as a regional office. Building was listed so no drilling through walls, PBX in the comms room, should be a simple case of connecting at the exchange right?
Nope, a previous tenant had cut the cables going into the PBX about an inch below the box and then somehow pulled all the cables through. Due to the nature of the building there was no way of knowing where the other end of the pipework was and it took a further 3 calls to BT and arranging for the managing agent of the building to be present to finally get the line installed. To the wrong office in the building.
