Sorry, but they do. I've been checking the call prices to make sure they're not too high.
The only negative I can see with Xilo so far is that there is a cease fee and there would be the cost of reconnecting to BT wholesale, should I wish to.
I don't think you fully understood what I was getting at, or I didn't explain what I mean't clear enough; I was on about included calls, as in a voice bundle. I wouldn't class the ability to make a call and be charged per minute as a "voice service" in my mind, but then again I can see why you said they do as technically you can make a call but get charged per minute

I wouldn't worry about the reconnection fee as if you went with TalkTalk you would face the same fee although theirs is 18 months until it's charged at a reduced rate!
Apologies if I came across abrupt, it wasn't intended - tone is hard to convey over the internet

If you go with Xilo let me know how you get on, I'd be interested to hear what their CPW service is like.
