I can't get any response dialing any number the intermittent tone just stays the same - I was hoping to fix it myself so I could cancel the engineer - doesn't seem entirely necessary to get an engineer but that was the only option when I looked online
Okay it sounds like more of a engaged tone than the intermittent dial tone you get when you have a new voicemail, only because you're not able to call out at all. Is that the only handset you have? If it's part of a set I would recommend unplugging everything from the sockets and just having one phone plugged in and testing again. Otherwise it would be a issue with the line and the technician would be required to fix it.
Let me know how you get on anyway, if you're able to get it working I can cancel the technician for you.
OK well apparently whatever phone the technician used worked fine so he says there is no problem - but I tested two completely different phones and neither one gets a dial tone. Both phones can't be wrong
