I used Verotel back in 1999 for about 12 months for my paysite. I then switched to ccbill. Verotel is every bit as good as ccbill (if not better). - except ccbill is more spam friendly
I am still an affiliate of sites that use Verotel as their main processor, and they are 100% OK.
You can see some of the sites using Verotel here:
