In reply to Phil1919:
Virgin may have a filtering system similar to 'Sky Talk Shield', look it up.
If you want to take more control, are reasonably technically competent and want to catch the bast#rds out, you can do this :
Port the number to a VOIP provider (like aaisp.net)
You can then get all calls to the original number directed to anywhere you like :
- Straight back to a landline
- To a mobile
- To a VOIP handset in her house
You can change this whenever you want very easily by logging in. Helpful if she may have to spend a bit of time in hospital, moves in to a home or even comes to stay with you for a bit.
You can also get it to record all the calls straight into mp3s, which can be emailed to you or just a gmail account as a store.
The log of calls is also very precise and complete. You can access it at any time and see the call duration and CLI's etc.
