I used to find that the ENUM lookup of voxalot causes a random carrier to be chosen, some don't connect and some have poor sound quality. This is not a fault of voxalot.
It is possible to force a particular provider that works for you by configuring it as a VSP with any username and password and then having a dial plan route the calls via that VSP.
I do this for uk toll free as I find that freenum.sip.telecomplete.net works best for me. For US toll free though, I agree with Kurun that using sipbroker is usually quite reliable. I have a dialplan to put the * in for me but you could just do it manually.
As far as I am aware you cannot dial uk 0800, 0808, 0500 via sipbroker. It does not accept *0800 as a valid code. This is why I use the VSP method above.
