Like many Virgin customers I am unable to accept a simple connection of my phone to a router.
I see constant compromises made by consumers, but little sign of customer consideration by Virgin. There must be other options?
Has your phone connection been switched yet or is it pending?
If it is pending, get VM to link your existing internal extension sockets to the hub's phone connection as part of the switchover process. They should offer this FOC as part of the switchover but you need to request it.
Alternatively, most cordless DECT phones allow the satellite phones to control answering machine functions and show missed calls etc. so your base station should be able to plug into the hub and still be controlled from elsewhere (maybe with the addition of a further handset if required).
Unfortunately, all providers are going this same route and with the same date deadline in mind so the change is coming to everyone whether we like it or not.
