Connected cordless phone to hub in living room but cannot hear it ringing in rest of house (3 bed semi). It was in ground floor hall at bottom of stairs & had a corded phone in first floor bedroom & could hear phones ringing from anywhere in the house. When connected to hub the corded phone works but will not ring. So only the cordless phone can be used & it is in living room. Rang Virgin Media on 150 & was advised that I will need to buy another 1 or 2 cordless phones to match my existing one. However my cordless phone is an old BT Freestyle 710 that is no longer available & I doubt that additional handsets will be available. Therefore I face having to buy a new set of 3 cordless phones that are hearing aid compatible for about £100. Or is there another way so that I can hear the phone ringing anywhere in the house. Any help & advice will be most appreciated.
This is one of those topics where the customer has their phone converted by VM and is left in a situation where their previously-functioning phone setup has now been rendered useless by VM's changeover and they have to go to great expense to fix it. Certainly a strange version of an 'upgrade'.
VM previously published info which advised they would connect up phone extensions free of charge during phone switchovers but that info has now been taken down and it just says to contact VM.
I would be pretty surprised, as you are a hearing aid user, if VM decide they are just going to leave you like this following the switchover with no further help.
If your corded phone is not ringing, it is likely this is because it is an older phone (probably early 2000's or before) and the hub arrangement is missing a component (which is present in the old wall sockets) which allows these older phones to ring. If VM linked your hub's phone socket to your previous phone sockets including the master socket you may find the corded phone worked again and rang. I am guessing that VM are now going to be trying to charge customers £25 for these wiring modifications in the future which would be a poor show.
Your cordless phone Freestyle 710 seems to date from about 2008 to 2010 so is not that new but not completely ancient either. You have a couple of options there perhaps.
A quick glance on eBay shows this model is readily available for low 10's of pounds
There is a guide here
which shows it can be connected to upto 5 handsets. You could maybe get some second hand handsets from eBay and add those to the system (usual caveats and warnings apply to buying anything second hand from eBay). You might have to match the exact age of the model carefully though to the same time when you bought yours (the model name may be the same but has perhaps gone through different versions and improvements over time)
The BT help page here (with a manual dated 2011)
also mentions it is GAP-compatible which means the system can work with other GAP-compatible phones but only in a very simple way (making/receiving calls but not any of the advanced phone features). You may be able to get a new GAP-compatible phone to add to the system. This might depend on the age of the phone as some versions of the Freestyle 710 say it is GAP-compatible and some older versions do not seem to mention it. There are a couple of free phone numbers and an email link for a helpdesk service for the model where you could get some detailed advice on if this would be possible or not at the link above.
Finally, you might want to just get new cordless phones throughout and have the reassurance they are all new. A triple pack of cordless phones would probably cost about £100. If you get new though, buy from somewhere with a good returns policy in case you run into an further unexpected issue with a particular phone model on the VM phone connection and need to return them.
