I need a router so I can use VOIP via Sipgate with the PC switched
off.

I'd been looking at the Netgear TA612V which seems to be available via
Sipgate but I get the impression it's no longer in production, I'm
sure I could get one, but I am wondering if there is anything newer
that might be better and cheaper.

I have a Virgin cable broadband connection and one desktop computer
and so need a router purely so I can use Sipgate VOIP when the
computer is switched off - I want to connect my home phones to the
router.

I don't have any sophisticated requirements - just need some pointers
to a router suitable for this relatively simple purpose. It would need
to be a well known brand with decent support.

Any suggestions please.
