I have an odd issue recently - I call a number and it's engaged so I push 5 to use ring back, get the "your ring back request is accepted please hang up" response and then my line is dead (no dial tone) for a few hours. It's always worked fine up until a few weeks ago. I did try calling but got nowhere.
Thank you for your post Ab101 and sorry to hear you're having issues with your landline.
Can we please confirm if you're still experiencing any issues? If so, please elaborate on if this is intermittent or whether you're able to contact the landline or if this is both failing to receive and make calls?
It's happened the last 3 times I tried to use ringback (over a period of weeks), I don't really use the phone that much and then it's rarer whoever I'm calling is engaged so it isn't that easy to replicate on demand!
It was still an issue last Friday. I haven't tried it since then. After requesting ring back and hanging up the line is dead for around 3 hours - no dial tone, no in or out going calls.
