A few months ago I went with Voipfone, partly based on my son's suggestion (though he's with Sipgate now), but mostly because they would supply a pre-configured ATA box. I had no previous experience of VoIP, and when I looked at all the SIP parameters I got cold feet about setting them all up on my own (my son doesn't live locally). With hindsight I realise that almost all of them are defaults, and I'd be a bit more gung ho now.
I've had a couple of issues, but Voipfone support has been excellent. If you don't have any of the optional extras, there's no monthly charge.
