I've run a search on the site here and got a couple of hits from customers with a similar situation as me but without much information.
I have BT Broadband and BT Landline services although the BT Landline is barely used these days
My broadband service drops out (i.e. the smart hub reboots) when I receive an incoming call over BT Landline.
A couple of things that I've tried
i) Unplugging my landline phone (its old and doesn't work very well)
ii) Taking the faceplate off the master socket and plugging an old ADSL filter that I had straight into the wall socket
Neither change helped, i.e. the service/router still drops and recycles afteran incoming call
Solved! Go to Solution.
sounds like you have a high resistance fault and need to report phone fault to CS 03301234150
