BT hasn't had any Indian or Philippine call centres since 2019, they're 100% based in mainland UK & Ireland.
As for call-back & redial I was merely pointing out that if telephone technology didn't move on we'd all be using one of these.
It's very difficult to give specific advice without knowing your exact telephone installation & how it's used, & personally I've found it difficult to work out, but we all try our best to help.
The main thing is that there will be someone who can sort everything out for you even if does cost you a few quid.
I follow Harry Callaghan's advice which is "a man (or woman in your case) has got to known his limitations".
I'm good at technology but not so good at replacing toilet flushing mechanisms so I pay to get them replaced.
I'm a returner to this forum, having been with Plusnet for 10 years & I was on their forum during that time, but those forum members do their best to help, as do the members on this one & there's no such thing as asking a silly or annoying question.
All questions are equally valid, I'm an interested dabbler in telephone technology while other forum members are experts.
Jane,
Would you not be better going with BroadBand only and then looking at VOIP lines for the other users in the house?
You don't have to go with BT's Digital Voice, there are other options avialable.
Just a thought.
