So, after almost an hour on the phone yesterday. I have tried all suggestions & I still have no caller display on my landline phone plus, because this is linked to the caller display, I cannot tell if anyone has phoned when I am out. Everything else is working fine & my phone contacts are all still there.
I've been told I need to enable my caller display from my end, I have never had to do. When caller display was added to Virgin package for free years ago, I contacted Virgin, they added it to my package & it's be fine ever since until last week. I've done nothing & my phone is working.
I believe I need an engineer to sort this out in the Virgin street junction box.
