Thank you for reaching out to us in our community and welcome, I am sorry to hear your phone isn't working since you received a new router, was everything Ok before this, has the phone always been plugged into the wall and not the router?
I have tried to have a look our end however haven't been able to find your account with the details we have for you.
I would be happy to look further into this to make sure the account hasn't been changed to being connected to the router instead of the wall socket.
I will send you a chat request, please click on the purple envelope to accept.
thanks for your reply - yes the phone has always been plugged into the wall and not the router. Since we installed the new router today the phone has ceased to work. The router is working for broadband.
Thanks for coming back to me with your details, I have had a look our end and run further checks, although I can't see anything standing out I have arranged a technician, the account holder can see this on their online account and change the date if not suitable.
