When we got home from the market yesterday the Telefoñica phone was dead - the screen was blank and there was no dial tone. The Internet connection was still there so obviously the line was working.
I tried the phone in different sockets around the house to no avail. I therefore assumed that the set was faulty. I went online and reported the fault to Telefoñica.
Within an hour or so the telephone came back on. I've had no message back from Telefoñica, so I'm still not sure what the problem was. I can only assume it was something at the exchange. Hopefully an engineer won't call out on Monday to replace the set.
