Non working landline since getting FTTP

[Leylo]

My FTTP went live on Thursday. I also got the phone service and transferred my home phone no. The instructions in the router say that an adaptor will be provided during set up but the Openreach engineer said it was nothing to do with him and I’d need to contact Vodafone. After several attempts to get through to the ‘xperts’ but being on endlesss hold both via phone and chat , I eventually got through to the standard customer services team. They told me that I was responsible for sorting my own adaptor and it wasn’t anything to do with them, despite what it says in the set up instructions about one being provided. They eventually agreed that they’d credit me with one if I bought it. It arrived today (the one on Amazon that’s been recommended here various times RJ11 to BT) I plugged it in to the router and nothing. Dead phone and an error message on my BT 8600 handsets about no line connection. I then went through the pain of contacting customer services again, and one hour 15 mins later still no working phone. He just told me that he’d reported it as a fault. 
Reading through some posts on here, it seems that I’m not alone! My question is, what do I need to do to get this sorted? 
Could it be a compatability issue with the BT 8600 handsets? Is the adaptor the right one?

I am having same issue, no dialling tone but rings on my mobile not on handset. Vodafone said get new phone. I tried this but still doesn’t work. What is the adapter that everyone is talking about

The recommended adapter is one like this: rhinocables RJ11 to BT Adapter Plug, Single UK Telephone Jack to RJ11 Socket with Tail Lead Converte...

But I don't think that is your problem. Is the PHONE led lit on the router?

And what do you mean by "rings on my mobile not on handset", they should be 2 completely different numbers

Meant if I call landline from my mobile I can hear it ringing on mobile but does not ring the landline phone

And, you do have the phone connected to the router?

[Shelagh055]

If so, did you use the "internet" cable supplied with the router?

[Shelagh055]

All sorted now internet cable was faulty. Son gave me a new one and works fine now. Thanks for all the advice

I had a similar problem using a BT Graphite phone set it never connected I used the cable supplied with the Router. After some weeks of no result a Vodafone second line agent said could I try a different phone. As luck would have it I still had an old Sirrus phone set plugged it in & it worked! I don't know why the Graphite wouldn't work but I bought a refurbished BT XD56 call blocking phone connected it & it worked! I still don't understand why the Graphite unit doesn't work as it was fine on the previous copper line. After all that waffle try a different phone if you can
