Maby you should try sms-billing instead of dialers.
More surfer friendly and it works very good in Europe.
The future is in sms-billing not in dialers because more legislatures throughout Europe are restricting dialers and premium rate number operators...
Smsmovies is what i am using as sms sponsor....it is a streaming adult video service that lets your surfers pay per view using premium SMS technology, which offers an alternative to the usual credit card and dialer services in Europe.
Surfer will automatically be redirected to the appropriate translated webpage based on an IP-check on surfer. If SMS is not supported, a credit card alternative is automatically presented for your surfer.
If you are starting your own program you can get sms billing numbers for example from

If you want to use dialers i think goodthinxx.com is best way to go at the moment
