If you have an attic in the house, it's perfect to route the telephone cable that way. That's what we've done, and we will also route the TV cable through the attic. (Today it also goes through a window frame). Keep in mind if you have plaster over the brick, to vacuum while you drill. If you have light plaster and, for example, red brick underneath, the drilling dust might unfortunately stain the plaster.
Good luck
