I recently moved and switched to Virgin Media. My Gigaset C475 voip phones seemed to work for about the first two weeks - although with fading sound, and then awful crackle - but for the last month simply say "Server not accessible" on the screen and admin panel. Calls to my voip numbers are cut off without ringing so the numbers are unusable. Nothing I do to the Gigaset settings makes a difference.
I've tried changing some of the - very limited - settings on the VM Hub 3 interface but with no result.
The engineer came today and checked everything which seems to be working well apart from somehow blocking my phones, but he was unable to help with "my equipment" so the problem is unresolved. The phones have worked on BT, Talk-Talk and Sky hubs over the past 5 years, and although now perhaps a bit old, functioned initially with Virgin. I don't think anything can have gone wrong with the phones or base unit, so assume the problem may be related to a Virgin update of some kind.
It would be helpful to know:
- if anyone else has had this sort of problem with VM?
- anything I could try to resolve it?
- of any other phones or items such as the Fritzbox that will definitely work with Virgin?
