Calls to Canada are not connecting from the Home 'phone, Portsmouth area.As a linked problem, the same numbers are not connecting on Three.
My home phone simply says number not recognised.Three phone says server error. Second Three phone has same problem.
Anyone know of a trunk routing problem? Nothing shows up when Googled!
I will answer this problem myself.
After a bit of research it turned out to be a broken fibre optic link in Canada somewhere.
Everything is now back to normal.
